Cheap aftermarket batteries have hit ebay!

Looks like the cheapo aftermarket battery manufacturers have got the Note battery reverse engineered and up for sale on ebay.
http://www.ebay.com/sch/i.html?_fro...galaxy+note+battery&_sacat=See-All-Categories
They're advertised as 2600 mAh (100 more than factory) and average about $5 apiece, with many listings including an external/wall charger for them.
I've purchased these for several phones in the past and it's hard to beat the value. They're waaay cheaper than authentic batteries, and my experience has been that they have nearly the same capacity as factory, though they don't last for as many charges. Still good for several months though. However, the last one I got for my GSII wouldn't charge when in the phone. If I plugged the charger into the GSII while one of those cheapo batteries was in it, it made a weird sound and the phone rebooted; it wouldn't charge.
I'm going to go ahead and purchase one of these listings and I'll update this thread with my experiences. If anyone else gets one before me, please post here which one you got and whether or not it'll charge while in the phone.

I ordered some - they use super slow shipping, but oh well.

I ordered too. A month til they arrive. Anyone know of any US shippers of batteries for the note?

US Shipper but batteries only no charger

nice... i wonder if they'd work properly with this http://www.ebay.com/itm/USB-Sync-Cr...043529?pt=PDA_Accessories&hash=item3cbecb78c9

So any update on this yet? Does the batter work well?

Actually, I just tested one today. I bought some of the batteries with a charger from one of the Chinese sellers and those are still on the way, but I bought another one from a US seller so I wouldn't have to wait. That one arrived yesterday, I charged it last night by holding it into an external charger with a rubber band, and put it in the phone today.
It's difficult to tell how it performed since my usage today wasn't that typical, but I'd say it probably had a capacity of 70%-80% of the stock battery. It lasted ~16 hrs with fairly heavy usage in the morning, followed by light usage in the afternoon, then a few hours in my friend's metal-walled shop, which usually rapidly eats batteries due to searching for signal.
I felt like I could notice the battery draining faster than the stock one normally does, but I'm hoping the capacity will go up with some charge/discharge cycles. This was the first charge and discharge. Regardless, I could definitely live with %75 capacity considering the price.
This battery is one of the black ones with white label. Not very scientific, but I only noticed 2 styles in all of the cheapo sellers' pics, and the other one is white. Those are the ones I have on the way.

If it's really giving you 70-80 in the first charge it may get as good as 80-85% of the stock one after five or six charging cycles ,and that ,for the ridiculous price you paid i say its a damn good deal.
Please review the white ones once you have them and thanks for the info.

No doubt they will, after all, the measures are standart so if the battery is made to fit inside the note it will fit in the slot of the charger.

Best value all in all, is the 3 batteries+wall charger pack, which I bought for the equivalent of little less than 10eur, before even buying the phone to save on the shipping time, but they are stll on their way.
Same kind of pack was glorious on my HD2, and the OEM's after a couple years last about half of the original battery (on android which has the suckiest battery management, got up to 4days with either original and OEM on Wm6.5), but oh well.

I bought this

Too bad
Take 12 hours to be charged, very long time
And ending in 8 hours

Just got some of these chinese batteries, the quality is horrendous, to the point I'm scared to use them.
You can actually tell that they have used a slightly small battery and put spacers in to bulk it out to fit the note!

I've had some time with both white and black batteries now. They're definitely not as good as the OEM. The white seem like it might be a little worse than the black, but that might be just my imagination.
My first guess was that the capacity of the black one was maybe 70%-80% that of the OEM, but that was a rough guess. Someone in another thread speculated that they're taking other batteries and just repackaging them to fit into the Note. I made a spacer for using my GSII battery in my Note (thread here on it), and the performance of these aftermarket batteries is kind of similar to when I was using the GSII battery but maybe a little better. The GSII battery is 1650 mAh, which is 66% of the Note's OEM battery.
In the past when I got cheap knock-off batteries for other phones, they usually performed a little less than OEM but not that much. They didn't last for as many cycles, though. I may build a capacity testing circuit soon and get some actual numbers...
Still, for $5 it's worth keeping one in your back pocket when going out for awhile, or taking 2 or 3 charged ones with you on a weekend trip so you don't have to carry your charger and search for outlets.

Mine arrived yesterday (black ones) and after their third charge they are giving me around 60 % of the juice of the original one.
Regarding the ridiculous times to charge it, it is because the ultra cheap chargers they send are 250-300 miliamp output (probably less in reality)
I use a universal battery charger that gives me 1 amp output so the battery is fully charged in about two and a half hours (a little less because the battery is probably 2100 or 2200 miliamps instead of 2500)

In another post someone suggested weighing their ebay batteries to determine if they were OEMs or not, I weighed mine. Results:
OEM: 49.35 grams
white cheapo: 45.1 g (91% of OEM)
black cheapo: 39.2 g (79% of OEM)
Clearly they're not going to perform as well as the OEM with less stuff in there, though I wouldn't necessarily equate the % weight difference to % capacity difference. But Samsung wouldn't be adding extra weight to the phone for no reason.

Huh, looks like the white being worse than the black may not be just your imagination after all.

Where can I buy universal battery charger that gives 1 amp ?

I just got 28 hrs moderate use out of one of the white ones.
I've installed Battery Monitor Widget Pro and I'm going to cycle through the OEM battery and one of the white ones for several cycles, letting some statistics build up, then in a week or so I'll post the results.

I bought mine a year ago in amazon. Brand and model, Ansmann digicharger vario pro. (Be careful, there is another version that is not the pro that only gives 500 miliamp output)
The good thing is that is one accessory you can still use when you change your phone in the future

Looking forward to that mate.

thanks Tiamath99
Is this the correct model
http://www.amazon.com/Ansmann-50251...1?s=electronics&ie=UTF8&qid=1323602651&sr=1-1

That's it, but you may find it cheaper somewhere.

Has anyone tested any of the replacement batteries?

Just looking for some feedback on some of the amazon/ebay batteries
Sent from my PG86100 using xda app-developers app

I received my Hyperions and universal charger yesterday. I'm not sure the prongs were adjusted to the right position on the charger. I charged one in the charger and one in the phone. After six+ hrs, the one in the charger had not completed. When I put it in the phone, it was at 56%, so I don't think it was right. I'll be checking for the correct polarity (positions). I ended up charging the 2nd one in the phone overnight. Took it off the charger at 7:00 this morning.
Because I only had the one battery, I have yet to fully deplete the oem battery.
I will post with my impressions after the Hyperion fully discharges and I can do the same to the oem one for comparision.

Got 27 hours out of it. Moderate/minimal usage. Had an appt. so couldn't wait for it to shut down. Meter said 12% when I changed it. But I'm very happy with 27 hrs..
Polarity was a bit clearer on the oem battery. I moved the sliding contact on the Hyperion charger to the first and third contacts and that seems to be charging correctly.

There is a video review of those batteries on YouTube. I think it's under the Zedomax channel or the High On Android one. Good review. I'm going to be ordering the charger and 2 battery pack. Only 20 bucks...

These charges aren't compatible with galaxy s III batteries. I've charged batteries overnight and come back and it's still only 91%, and the full charge indicator is blue.

Has anyone ever has good luck with generic batteries? I've tried various ones from eBay or Amazon with my last three phones and thought they sucked compared to the oem. I swore to just buy real batteries this time.

Just to clarify, the NFC chip is in the battery, so 3rd party batteries will be missing this

Yep no chip. It's good as a spare battery still.
And I can back up the thing about the charger. It never did give the oem battery full charge. It's a POS in my opinion anyway.
The OEM battery gave me just slightly better time until it got down to 14%. So i think these Hyperions are pretty good notwithstanding the lack of the chip.

I happen to really like my Hyperion batteries so far. They seem to last just as long as my OEM battery.
When I use the Universal Charger the highest I have gotten the batteries charged up to has been 96%.
It takes a very long time to charge them. You know that you have the prongs in the right place if the light lights up blue when you connect the battery to the charger while it is OUT of the wall sockets. When you plug it in to the wall it will turn a pinkish red.
I hope that helps

I bought two Anker batteries. I had great luck with the Anker batteries on my Captivate, better than stock and way better than the generic batteries.

my hyperion batts work great but the charger is crap im going to take it apart and mod it at work so the pins wont move see if that helps..but the usb port on the side works good for charging the phone..no NFC but very good battery so far plus i need to cycle it and break it in..the OEM one has more use like said before.. but this battery is good for back ups .. im looking to get a OEM samsung charger with the battery/spare/dock..i think im good with 2 batts.. 2 OEM batts should work out for my use but now ill have 4 batts
i love this replacing battery..unlike iphone haha no more buying iphones for me

There was a time when the only spare batteries I bought were Anker. They make high quality aftermarket batts that's for sure. Did you receive these yet? Do you like them?

Yeah I just posted the same on my thread......gonna get the dock charger w/ oem battery. I think I'll be giving the nfc tags a try so will want an oem battery for a spare.

I have the same issues with the Universal charger that came with Anker. 95% is the max I can get out from it.

China batteries
NOTE: I have not tried this for my gs3 but i had the same brand for my droid x and I must say they are not as high quality as the OEM (of course) but the price for 3 back-up batteries are priceless also if you are having troubles with the chargers, this one fits perfectly and charges them full.
Also does anyone know if using non-OEM batteries will in turn degrade the life span of the original battery?

I picked up sime batteries that are marked NFC, but I'd like to verify that they are indeed NFC capable.
Outside of going to an NFC enabled credit card terminal, or testing it directly with another NFC enabled phone, is there a way to verify that it is indeed an NFC capable battery, like an app? Thanks.

Warning! watch out for the Fake batteries on ebay
I bought a couple batteries to test, but I was extremely disappointed. No NFC chip, just a good sticker on a real crappy battery.
Don't buy from:
shinging2011
2 x 2100mah OEM Battery + Dock Charger For Samsung Galaxy S3 18.99
I barely get about 8 hours with either of these and now on of the pins broke on the charger.

Meh, prob'ly don't get these
I got these "2500mAh" via Ebay.
I properly "conditioned" them both, as well as I could. One lasts just a little longer than stock. It's a decent replacement battery, and it was cheaper than the Hyperion. The other doesn't charge all the way, ever after 15 hours total on three different chargers, so it's a dud. I haven't followed up on it yet. (I was going to do a proper test, but I just haven't had a day/evening off to do that either.)
My guess is that streaming video at full brightness with all radios on, the good one would last another 10 minutes. I rather think the risk of getting a bad one isn't worth buying them.
After I recover from my phone accessory binge, I'm planning on buying a proper OEM with the NFC chip. I'm getting addicted to it, even without being able to shell out cash with it, and I'm tired of how fast the cheap batteries (four months to a year or so) end up not taking a charge - I've gone the cheap-battery route since the HTC Wizard (released with WinMo 3.0), and although I can't complain too much, I've ended up spending just as much on replacing the cheap stuff as I would have buying the real deal, but with more hassle and more garbage. (Sorry Mom Earth, I'll do better next time.)

Put it in an NFC-capable phone (that works with the OEM) and see if it beeps when you hold it up to a $1 tag.
I'm finding the tags indespensible around the house. This technology is going to be amazing for groceries. I'm jonsing for a wifi-connected refrigerator with a reader in it.

I don't really care about the NFC capability, but I too am tired of buying cheap batteries that just don't work well. I'm really wondering if the extra money is really worth it for the legit OEM batteries. I've only had my S3 now a few days and haven't really had a good chance yet to evaluate battery life on the stock battery.

Review of Anker Astro Slim3 6000 mAh external battery and stand w/lots of pics!!!

This is a review of Anker Astro Slim3 6000 mAh external battery: http://www.ianker.com/product/79AN7909-BA and Anker Multi-angle stand: http://www.ianker.com/product/77ANSTAND-SA
It has been awhile since I posted a review in Nexus 7 section of the forum since Note 2 is my homebase. But considering extremely thin design of this external battery slice and a tablet stand - this makes it a perfect companion for N7. Of course, battery is universal and stand can be used with a tablet or a smartphone.
I have been a huge fan of Anker external batteries, reviewed a lot of their products, and always impressed with a quality and 18-months warranty. Another great thing about these - constant refresh with updated design and increased capacity. Battery cells are slimming down, efficiency of capacity improving, and I'm glad Anker keeps up with all these changes.. Slim line is very unique since it offers one of the thinnest available external batteries with a built in usb cable/connector and a very decent capacity! In comparison to Slim2, this one increased a little bit in length and weight, but still at 134 mm x 70 mm x 12 mm and 155g of weight - it's super slim and portable to carry it with you in a pocket. The battery case itself is very sturdy, feels no flex, and with a matte finish and rubber material around the edge perimeter - makes it very comfortable to hold. Charging input of the battery is micro-usb port which also serves as a storage for one of the outputs with an attached cable and micro-usb connector. In addition, there is full usb port output. The input is rated at 0.8A which means it will take about 6-7 hours to fully charge this battery from empty, while both of the output ports are rated at 1A each which means you will get a full charging speed from those. And while you are charging the battery, or using it to charge your device, you have 4 leds indicating battery capacity in increments of 25%. I also would like to mention that although built-in cable with micro-usb connector is great and means one less cable to worry about, the connector itself is kind of thick and might not work with every case. That's where the 2nd full size usb charging port comes in very handy!
The performance of this battery was really impressive too. As you know the total capacity of the battery is not the actual capacity because of loses through conversion from internal cells through 5V usb interface. External batteries usually loose 30% of its rating by the time it gets to the tablet/smartphone internal battery. In case of Astro Slim3, I ran multiple charger/discharge cycles and on average found that you can actually get up to 4800 mAh of the charging capacity. That is 80% efficiency which is very impressive. I looked up reviews of other Slim3 users and saw people reporting similar results which is consistent with my testing. But often you have to set your device on a surface to plug in battery for recharge. Carrying both together is not very convenient. With Slim 3 you can actually do that with ease. I'm using book-cover case where I can wedge the battery and continue using my tablet while it's charging up. You can see it clearly from the pictures below. That setup is very convenient, especially if you are playing power draining games or watching a movie, or in general when you don't have time to wait for battery of your tablet/smartphone to charge up. In my opinion, this battery is a must have considering its portability and high capacity.
The pictures are below.

In addition, I'm also reviewing Anker multi-angle adjustable stand. It has a very nice weight (172g), support surface of about 4" x 3", adjustable angle (push the side button for adjustment), and a very elegant sturdy design with lots of rubber padding. It can accommodate both landscape and portrait orientation. I do have to mention that for some smart devices with a thicker case, the opening in the stand might not be wide enough which could be fixed easily by removing inner rubber padding to expand the space. So for example, naked Nexus 7 fits without any problem. With a thicker case you can remove inner rubber lining of the stand to make more room. Great product as well!
Here are the pics.

Nice reviews! I've been a fan of Anker products since I came across them about a year ago. I own numerous car/home chargers made by them.
I've been wanting a battery pack/charger for some time but there are so many sizes/types/brands available it makes my head hurt.
Thanks for helping me narrow down the choices a bit!

Grab a beer, and head over to my complete review section in the link of the signature Actually, that will not help you much with narrowing stuff down since I have dozens of external batteries in there, but at least reviews will give you more details

Great reviews! I'm considering buying the Anker Slim3, since I just broke my Slim 2 (don't carry it in your back pocket while on a 2-hour drive). Would you be able to get a picture of it next to a smartphone? I've got the HTC One and I'd like to be able to see how it compares in size. The Slim 2 was great, and the only time I ran it dry was when I lent it out to three other people who had dead phones. Of course, theirs were a lot smaller in size.
Actually, you mentioned the Slim 2 in your review, maybe a picture with one on top of the other? I'm just terrible at visualizing the size of things from measurements.

Nice reviews, by the way i like your desk.

The Astro Slim3 6000 mAh finally came back in stock so I ordered one to try out.
One thing I'm liking about this battery over others is the finish. A majority of the battery packs available currently (including many by Anker themselves) have a glossy finish which is extremely scratch prone. I prefer a matte finish for both aesthetics and grip.

Thanks for quick review, I've just ordered 4 of them (Astro Slim3 6000) for a whole family

My Slim3 6000 mAh arrived today. I like how it arrived with ~ 75% charge already. Î like the finish and it feels solid/well made. Thanks again for the review!

I'm looking for a pull tab case for said battery, anyone know which one will fit?
The battery is the size of LG 4X (4.7"), but thicker. If anyone uses one already, please suggest one, otherwise I'll go to a store and try all of them out.
So anker size is : 5.3 x 2.7 x 0.47
The closest I've found so far is Lumia 920 at 5.13 x 2.79 x 0.42. Do you think it would fit?
edit:
none fit. I went to a store and tried every single one of them and except for the one made for Note, all were too small. The Note one, however, was too big.

Thats really wierd, it has 6A capacity, input rate is 1A so if you charge it with charger >1A, it should take no longer then 6 hours (add one for good measure), trough USB port (0,5A), it should theoretically take 12 hours to charge.

Yeah when I say night I meant sort of 6-8 hours. That's still around 20 hours for the whole thing, but who cares when I can charge two phones at once, twice!

And when I say 6hrs I mean fully charge, not just 25%. It's weird that it takes so long...
I haven't had to recharge mine just yet (I'm mostly home until october), so I don't know exactly. But yes, it should hold enough capacity to charge 4 phones
edit:
So I fully charged the Lumia 720 (2000mAh battery), half of Arc S and half Nexus 7 and Anker was drained. It did however fully recharge in less then 12 hours (I plugged it in around 19.00 and left it until next morning when it was full) so not even close to 20 hours. I was charging it with >1A charger, maybe you were charging it on the computer USB port (500mA) in which case yes, it takes forever.

So what do you think of these results I documented with my Slim 3 ?????
After unboxing my brand new Anker Slim 3, I fully charged it, fully discharged it, and fully charged it again.
I wanted to test the new Slim 3 to see it's charge times, and capacity, so I chose a weekend day so I would have very little usage of my phone.
I proceeded to cycle through fully draining, then recharging, my Motorola Photon Q LTE's internal 1785mah battery until the Anker Slim 3 was fully depleted.
- 11:30 AM Saturday: Anker Slim 3 fully charged and Motorola Photon Q LTE @ 9% @ 11:30am
- 1:39 PM Saturday Photon Q LTE charged to 100%. Anker Slim3 has 3 shining dots left (2:09 hours of charging)
- 12:00 AM Sunday Motorola Photon Q LTE at 4%. Slim 3 is strangely at 2 shining dots. (although, it had 3 dots when I unplugged it last from the Photon Q) (Motorola Photon Q LTE discharges 96% in 10:21 hours)
- 2:15 AM Sunday: Motorola Photon Q LTE at 100%. Slim 3 at 1 shining dot. (2:15 hours of charging)
(Motorola Photon Q LTE discharges 25% down to 75% battery life while sitting on a dresser for 8 hours)
- 7:30 PM Sunday Motorola Photon Q LTE at 1% and connected to Anker Slim 3 with 1 shining dot.
(Motorola Photon Q LTE discharges in 17:15 hours )
- 8:05 PM Sunday Slim 3 stops charging and 1 last light goes dim. Motorola Photon Q LTE left with 40% charge
I love the Anker Slim size and form factor.
I just bought the Slim 3 to replace my Slim 2 that suddenly stopped working without reason.
Other than the fact that my Slim 2 died without reason, I would recommend the Anker Slim line.

Nice Review indded.
Any chance to see a size comparison between the slim2 and slim3?
Can't determine which one would fit better in my accessory bag
Thanks!

REVIEW: HTC One battery case - Mugen Power 3,000 mAh black battery case - CC-HTCONESL

I originally posted this on another forum, but i thought i would post it here too. I have had great success with this companies products for all of my HTC Phones. I have used their products in both my Tmobile G2 and HTC Evo 3d and now since they don't offer an internal battery for the HTC One i had to try the case.
This is my review of the Mugen Power 3,000 mAh battery case. The model number is CC-HTCONESL. This case is the smaller one in their lineup at 3,000 mAh they also have 5,000 mAh case and each version comes in either white or black.
I have been using this case myself since Nov 5th now and i have been extensively putting it through performance tests making sure it has repeatable and reliable performance. So far it has been great, but more on the performance details later.
Here are some pictures of the case itself. You can see the writing on the inside of the case which shows the input and output amperage of the case. It will take longer to charge on a power source of less than 1 amp of output, but works fine if that is all you have.

Here you can see the packaging card and the back of the case with the 4 blue led indicators as well as the button to check the state of charge. The case has perfect cut outs for the camera and flash, as well as one for the upper microphone. Call quality appears normal with the case in use.
Here is the other side of the packaging card with the information on it.
The case simply charges with the same charger you use to charge your HTC smartphone with a micro usb port. You can even leave the case plugged into your phone and charge the case and phone with 1 charger. The case will first charge your phone fully, then charge the case. If you have two chargers, you can simultaneously charge the case and phone if your are short on time.
The case features features 4 blue LED lights for checking the state of charge of the build in Li-Polymer battery pack. It has a red led light near the micro usb port indicating the case is charging and the light will turn green when the case is full.
The case is very simple, you lay your phone into the case and gently press it into place. The phone is charged through a hidden micro usb port that lines up with the phone. The wire and micro usb tip will tuck back into the shell of the case with only the end sticking out for easy retrieval. The wire extends approximately 1 inch from the case. Bonus, you could use this case to charge any micro usb device in an emergency!
You can see a picture of the side of the case with the phone installed. The HTC One is very slim on its own so most all of the extra thickness comes from the case itself, which is not too bad. It still slides into my pocket easier and now is easier to hold because it has more weight to it. I found myself always feeling like i was going to drop the phone without a case due to the light weight and skinny form factor.
I don't have any calipers handy for a precise measurement, but i noticed the case was just a little slimmer than a US nickel. A nickel is 0.835 inches in diameter so i would estimate the total thickness of the case with the phone install at about 0.8 inches.
Here is the sim card side of the phone with the nickel.
Here is a shot of the side of the phone with the case installed. After i looked at the picture i just took, i noticed the phone was not pushed all the way into the case but it still holds firmly even if not pressed fully. I have attempted to hold the case and shake it as hard as i could and the phone will not dislodge, but dropping the phone could certainly cause that.
Continued on next post, due to 10 image limit.
Here is the sim card side of the same setup. Sim card is fully accessible with case installed.
Top of the phone with case. Headphone jack is fully accessible with case installed.
Bottom charging port is fully accessible and bottom microphone is fully open too.
PERFORMANCE!!
Okay now my favorite part the performance side of the case. This was by far the biggest reason i got the case. You can say what you want about the looks of the case, or how it leaves the front of the phone unprotected, but performance is what its all about.
I tested the case many different ways but to eliminate some variables the way i typically charged the case was to put the phone into air plane mode after reaching near 0% and let it do its thing. I have the Battery Bot Pro app installed on my phone which is very handy.
The first shot you will see is a screenshot from my device after charging with the case for just under an hour (57 minutes) The case is able to charge the device up to 40% in this short time. You can see the phone thinks its getting an "AC" charge even though this is a DC source, this is a good indication that the device is delivering the indicted 1 amp of charge rate.
I left the phone alone awhile longer and came back to it at 68% after 1 hour and 42 minutes of charging.
The last shot is of the case fully depleted from a full charge. It was able to charge my device from 2% all the way up to 87% in only 2.4 hours! The voltage on the battery ended over 4.20v, while a full charge on this device is closer to 4.35v.
I am very happy with the performance of the case. I have been using it daily since Nov 5th and It was able to repeatedly charge my phone from near 0% all the way up to 85-88% over and over again. Even though this is a 3,000 mAh capacity battery in the case you are going to lose a lot through the electrical efficiency since its charging the same type of battery and has to step up to 5 volts. This type of efficiency is typical of battery cases and nothing abnormal here.
A more typical usage of the case would probably be to plug it before it was close to dead and unplug the port when the battery is depleted or when you have gotten enough charge to make it through the day so you can leave your port protected inside the case .
PROS: Power on the go, protection to the back and side of the phone, Uses the same charger as your phone, battery indication for state of charge, fast charge rate, leaves all the ports and opening on the phone available, makes phone easier to hold, ability to charge other micro usb devices in emergency
CONS: Leaves the front face of the phone open to damage if dropped, micro usb port is vulnerable when plugged into the phone and on the go, possibility of damage if rough
Summary: A case for true power users, who love the HTC One but can't make it through the day without needing a little extra juice! Casual users would be more suited to using a full protection case that offers front bezel protection.
The case is available directly from Mugen for 89.50 with free worldwide shipping and tracking included in that price.

Well its not as big as the larger 5,000 mAh version they make but remember your phone is no good to you dead, so having power when you need it beats comfort with a brick. The mophie juice pack looks pretty sweet, even though its rated less, i only use about half of my Mugen case to make it through my long 12 hour work day. I might get a Mophie too!

nice review..very detail.. hope u would also give some review if/when u have mophie..

I also ordered this model in white color only. Parcel will arrive next week. To be honest, I'm disappointed! When ordered, the Mugen Power has not posted photos of the place of connection. Connect your phone so awful plug I do not like!

It's a little different i understand, but it's useful that it can be used on other devices if you needed to even though the wire is short. Hopefully you enjoy the extra run time away from the wall though.
lately with mine i have been waiting til my phone gets to about 50% and hooking up the wire and leaving it in my pocket while at work so it can get a decent charge for a hour or two and then i have enough to make it through the day.

That's basically how I use my Mophie. I wait for my One to drop to 20%, connect the Mophie, it'll boost it back up to about 85%, disconnect the Mophie, have battery life until midnight.

The One comes with a 2,300 mAh Li-Po battery which is already pretty stout compared to other phones even the stock galaxy s4 battery is only 2,600 Lithium ion, so not too far off. It's mostly the high power consumption off all the high performance hardware that's killing battery life. People who use the phones for basic things like calling/texting report pretty good battery life in powersaver mode.
I do wish the battery would last longer, but this is going to be a problem for anyone using the phone for high consumption apps.

Great review. Handy product, i.e. if you're going camping this should last atleast a weekend with moderate use

With me working 12+ hours per day I don't know how I would manage without the extra juice. I use a lot of juice just on my breaks but also weak signals or nothing signals drain it too, and if refuse to use airplane mode after I've missed important messages in the past.

I highly recommend this battery back, I got one and so did my friend. We went disappointed at all.

I was in the market for a large capacity power bank and really liked the look of this one on Amazon. Shipping was very fast as it was fulfilled and shipped by Amazon. In this review i will go over the Features, First impressions and Final thoughts after using the power bank for some time.
Features:
Ultra-slim design with a hard plastic & aluminum alloy construction
High capacity 20,000mAh
Two USB charging ports (5v-1.0A/ 5v-2.1A)
Micro USB input for charging the power bank (5v-2A)
Blue LED digital charge indicator
Built in over-charge, and short circuit protection
Dimensions: 6.8 x 4.8 x 0.5 inches
Compatible with any USB charged products such as iPod, iPhone, iPad, Android tablets and phones, ETC.
First impressions:
After receiving the power bank the first thing i noticed and was pleased with was the packaging. When you buy a product you expect there to be in professional and quality packaging and they definitely did that with this power bank. After unpacking the power bank and holding it i was very pleased with the aluminum alloy construction. When researching power banks the materials used was one of the main factors for me choosing this one over some of the others on the market and im glad i did, In the hand the build quality and construction feels premium just like my HTC one and iPhone. While it is a slim unit i would not say its the lightest power bank it is after all 20,000mAh capacity which is a larger power bank . If you are interested in smaller lighter package you will also be shrinking the battery capacity so that was something i wasn't willing to compromise on. First thing i noticed during use was the digital LED capacity readout. This is a premium feature that also was a top factor for me choosing this power bank. With a quick slide of your finger across the read out screen you can see exactly the charge you have left, No more relying on the few led lights the other banks have to judge how much juice you have left. Overall my first impressions of the power bank was very positive. Between the premium build quality and features included i was very happy with my choice. Amazon LINK
Final Thoughts:
After using the Power Bank for some time my initial opinion did not change, In fact im not sure how i lasted before without one. The quality of the unit is outstanding, Being constructed from aluminum gives it some serious durability, and looks brand new after heavy use wile camping, traveling, beach trips, and school/ work. The battery capacity is outstanding, as a power user Ive always found myself killing my phone battery far to early in the day and now i always have a charger even wile away from on outlet. Ive also found it very useful for camping trips and power outages due to the large capacity you can charge many items on one single power bank charge which is very handy in those situations. Overall am very pleased with my purchase. Between the stylish build, quality of materials used and the overall charging performance i would recommend this to anyone in the market for a power bank. Amazon LINK

I bought 3000mAh for my Nexus 5 and both times I used it - it had problems. Once I unplugged it, within few minutes my phone went off, no buttons worked, nothing, dead. I kept pressing, holding different combos until it rebooted somehow. Never had such problems before, but both times I tried to use power pack. I did read online that other people have had similar issues by phone getting confused and shutting itself down. So - no more external packs for me

I love this. 20000mAh is super high capacity power bank on the market.
the aluminium alloy looks very classy.
But how many times can it charge for Nexus,or other hot android phones like Samsung note 4,HTC M9,etc.?
I think charge times is a very important info. but it wasn't provided here.
and I think the power bank might be a little too big. Am I the only one who have such thoughts here

Yea I can see how that would be annoying. Haven't had that issue with this pack.

Yea it is a bit on the large size but you really can't help that with the large capacity, this brand also offers smaller capacity aluminum banks. As far as times goes its depends on the USB slot you use as there different amps but its very similar to the stock charger time wise. Also all phones have different battery sizes, the n5 has a 2300mah battery so you get around 8 - 8 1/2 charges on a full power bank.

Ordered two

I got one and test it for capacity, it is great value for $/Ah. it cost 38$-39$ at ebay and aliexpress
the size is good, if someone need smaller size/less capacity vinsic have other models.
from the cell i learned they use high grade LiPo cell from LG , and in small ones they use Samsung 18650 cells, not some fake chinese cells...
It have real ~13500mAh (20000mAh * converter PCB Efficeincy factor ~0.67) capacity available for recharge devices.
if you want to know how many times you can recharge your gadget (phone, tablet etc...) use aproximate calculation
13500mah / your device capacity * device charging efficency 0.8 = aproximate charging times.
for example i have 2600mAh battery in my Galaxy S4 so it will be
13500 / 2600 * 0.8 = 4 full recharges. It give me freedom to use cell phone without outlet for really LONG time.
I can recomend it...

Wooow 20000mah it s awesomeee,I was looking for an enourmous one to take with me when I do some camping...From the pictures looks very well built and i like the battery indicator,wich contributes to assure you about the quality.I had 2 chinese no brand powerbank,but they looked cheap in building quality and engeneering chose, like the bicolor red green led to tell the remaining life (I don t need a red led to know it s 0%,a yellow one with the red and green led lighted up to tell me the 15 or else % could be a better use of bicolour led ) or the stupid second one with an uv led that was meant to tell battery % ,but likes was written in manual to tell if you have a fake banknote or not (ahhahh how stupid is that???).
I want one, they produce even other power banks looking from they re site,the wood one is looking awesome, and other accessories ,all looking goods and not resembling to other brands. So they could be a serious brand . I look if I can get this one and they re car charger from amazon (2 usb 4.8A ) i need it for my nexus 5 and nexus 7, then I will tell you about the quality after some stress tests

How long does it take to charge?

I'm so getting one of these when I get paid again. I have a 10,000 mAh one, but it takes freaking forever to charge.

Is the battery capacity indicator activated by touch?

It holds 20 amp hours and uses a 2 amp charger so 10 hours.

Great! Is it hot during charge?
_____________________________________Read more write less and be smart

I got one after looking into it and I'm so happy I did .I've a pile of packs .most 1200. Needed a bigger one and I'm impressed with the quality and it's storage once it's been cycled a few times. I used a one amp charger as it's all I had but bought a two amp which it needs .buy one they are superb. It's like an Apple accessorie with the aluminum unibody design. Gives no neat charging or discharging. Get a kindle case to keep it like new

I keep mine in my computer bag while traveling so it serves the purpose the way I was hoping.

Now that I own a nexus 6 this looks like next purchase

I want this one but it seems so big, I guess I'll just have to get it and try it out.

Looks really well made for being a battery.

It should be 2A charger, so should be fast..
