I'm currently looking for suggestions and feedback on and external battery power extender specifically for my Nexus 4, and maybe for an iPad occasionally.
I've been skimming online all day, looking at different brands and models. One battery that seems to fit my needs is from a company named New Trent:
http://www.amazon.com/New-Trent-NT7...qid=1367450278&sr=8-1&keywords=newtrent+nt70t
Anyone have any previous experience with this company and their products?
I'm mainly planning to use this to keep my phone charged when I'm not near any wall plugs or when I'm on vacation.
How much extra charge should I expect from this battery pack?
Any insights on this would be much appreciated.
I don't know about their batteries but they do make some killer micro fiber styluses.
You'd probably get 2 good charges out of that back up pack, assuming their #s are solid.
I haven't tried that specific brand, but I have used a few others. I currently use the Motorola P893 (89536N) which is only an 1860mAh battery pack and I get about an 80-85% charge on my Galaxy S II 1850mAh battery. So if it's anything like this one, expect about 80% of the rated capacity to be actually usable. Thus 7000mAh would translate into about 5600mAh of useable juice. The Nexus 4 has a 2100mAh battery, so I would guess you would get a solid 2 charges and still have some juice left over.
Hope that helps.
Monoprice.com has a nice external pack for a great price. I have one and like it.
I can't post links yet, but its under $29 for a 5000Mah pack.

Interesting, going check this site out
New Trent
I am a beta tester for New Trent and they have wonderful products. I currently have the PowerPak + NT135T. It has 13500 mAh which is huge considering most phones have close to 2000 mAh. I can charge my Nexus 7 (2013) and HTC One at the same time without a hiccup. It's only $54 and can recharge a Nexus 4 5 times.
If you go on amazon and search for external batteries, the #1 brand with thousands of 5-star comments is Anker. I have reviewed every brand of external batteries, and wrote a ton of detailed reviews in the sticky of this Accessory section of XDA (and in my sig link). I have looked at Anker, New Trent, RAVPower, Yoobao, etc... A lot of good trusted brands, but customer support, warranty (18-months), variety, and recent 2nd gen introduction to stay ahead of other cookie-cutter CH generic brands really sets them apart.
Hi all!
These days I'm planing to purchase a portable battery charger for my Galaxy S3 I9300. I need to know three things about the portable chargers.
1. What are the features that I should search? Eg: mAh.
2. What is the Galaxy S3 Output Current and Voltage?
3. I search on local market and I found one Energizer power pack. It's 4,000mAh one. It price approximately US $ 80. What are the other good portable battery chargers?
Thanks!
Here's a better/cheaper choice
iBattz BattStation Tough Dual Pro 7200/8400/12000 mAh
8400 mAh = $49.95 & FREE Shipping. (Amazon)
There are so many mobile chargers on the market.
The important things you should take a view on are:
- capacity (compare with the 2,1Ah battery on the S3; but take care, mostly the capacity is calculated in theory, these are not actual values!)
- size
- weight (this point is mostly connected to the capacity, so be aware of that)
- number of devices, which an be charged at the same time)
- time to charge the charger
I think you can use the ratings on amazon to find out a charger, which fits zur demand
The energizer packs are solid, but as mentioned definitely overpriced. I feel like I'm preparing for the apocalypse with the number of these I've purchased over the past few years but they've all come in handy. In the end the company I feel is most reliable is New Trent, who's battery packs also happen to be some of the most affordable.
If that capacity works for you, I'd probably go with the New Trent IMP52D, its 5200mah (which I've found to be pretty accurate with my S2 Skyrocket and S3) and is extremely small considering. Its also only $29.95 shipped. Right now for anything other than trips longer than a weekend I mainly use the Easypack NT70T (y000mAh) because I like the convenience of the built in USB cord for charging, and built in micro-USB for my S3.
They have a few new models I haven't used that look to pack a lot of power into some pretty impressively small packages but most of those are 10,000+mAh and probably not what you're looking for. I own batteries from about six different companies, and New Trent's have definitely been my favorite, take a look on Amazon.
I have this and have no complaints.... 10,000mah for $40 http://www.amazon.com/gp/aw/d/B009USAJCC/ref=mp_s_a_1_1?qid=1372499185&sr=8-1&pi=SL75
Sent from my GS3
One of the highest capacity battery packs I know of and have tried out is the Limeade. A bit large in size for my liking, but for 18,000 mAh I'm not going to complain. Definitely has juiced up my Nexus 10, 7, and my S3 with no issues.
You can get it off Amazon for about 100 USD.

There are many on the market from cheap crap to good quality product, these days you will need the largest mAh you can afford, also consider the brands and what cells it uses (samsung, sanyo, panasonic and hitachi etc.), as many cheap stuff don't meet up their expectations. As for input at least 1A and output at least 2.1A.

I bought this one:KINKOO ,it works well ,i have charged my phone 5 times already and it still has juice in it.the Infinite One has a massive 8,000 mAh capacity and intelligent output control system(no matter which phone use), it can Compatible with all Apple and Android smartphones, Tablets, GoPro Cameras, MP3 Players, Mobile Gaming Devices, Bluetooth Devices, and other USB charged devices.i think that is good,if you like it ,you could check this brand in google.
Best Portable Battery Charger
Hey!
The foremost feature that you should look for is its compatibility with all the devices. Considering the battery capacity is also an important aspect.
The Galaxy S3 output voltage is 5.0V while its output current is 700mAh.
If you are in search of a 4,000mAh portable charger then the one you found is quite costly . Check this one with the same capacity but quiet a low cost i.e Flux Portable Charger.
This is a review of Anker Astro 3 (new 2nd gen) 12000 mAh external battery: http://www.ianker.com/product/79AN7904-BA
*** The Review of the Updated version was posted here: http://forum.xda-developers.com/showpost.php?p=51836263&postcount=62
***
Yes, another external battery. No, this one is like nothing I have ever tested from Anker or anybody else. It's not a surprise Anker became one of my favorite companies to review new products from because they are constantly introducing something new and/or improved. That is the only way to stay on top of the game and to earn the top rating of your customers.
First of all, even with it's 12000 mAh capacity, this new 2nd gen Astro shrank up in size down to 110 mm x 83 mm x 26 mm which fits very comfortably and feels very nice with its soft touch rubbery finish in your hand. At close to 10 oz in weight you will feel it for sure in your pocket, although it's slick design is very portable and with included mesh pouch is easy to carry around in your bag/purse/backpack or even pants pocket, as long as you are not wearing skinny jeans In contrast to most of the today's external batteries with dual output, Astro 3 comes with 3 independent full size usb outputs that deliver a whooping 4A of combined current. I checked it by charging Note 2, S4, and Nexus 7 simultaneously and was able to confirm that right on a dot. N2 was charging at about 2A, S4 at about 1A, and N7 at about 1A as well. I was actually timing and monitoring the percentage of battery change, not just relying on Current Charge app. These 3 usb charging outputs are actually partitioned into one Smart output (intended for Apple devices and other android devices) and two Universal outputs which are specifically designed to charge Android devices at maximum speed. There is some custom circuit which determines max speed and optimizes output correspondingly. I also noticed the safety nature of this circuit prevented me from charging both N2 and S4 at 2A each from Universal outputs where N2 was charging at 2A and S4 at 1A, leaving 1A for Smart output, thus confirming it's not a bulk current sharing between all 3 ports. The input port, micro-usb, for charging Astor 3 is actually a fast 1.5A input which is great since it charges this external battery at 1.5x times faster rate.
While you charging the battery itself or using to charge other devices, another huge improvement in the design is a circular 10-segment indicator with granularity of 10%. You no longer have to rely on a typical 4-segment led. This one will give you a more precise reading, although it might take you a little while to get used to figuring out on a spot the exact percentage by counting segments before light times out. Once the light turns off, it's a clean surface design with no leds or buttons. So how do you turn it on or verify led count? Yet another cool innovation, just do a shake of the battery and indicator circle turns on to reveal number of active segments. I really like that motion activated switch, makes it very unique. But trust me, it's not the most unique part of this new Astro 3 design. As I mentioned in a number of my previous reviews, the labeled capacity of the battery is not what you actually get. It's the capacity of the cells inside of external battery when it has to be converted to 5V usb interface at the output and then back from 5V to 3.7V inside of the phone. During this conversion ALL external batteries loose anywhere between 30%-35% of its capacity. Well, this new 2nd gen Astro 3 is optimized to a much higher efficiency. I have tested it and can confirm it provides the actual charging capacity of 10,044 mAh, which means a loss of only 16%!!! Basically, the internal battery circuit has been optimized to provide a more efficient output. I have tested a lot of external batteries, and this is the first one I have seen at such high efficiency.
Overall, I was very impressed with a design and features of this battery, especially with how efficient it's output. Currently offered for $49.99 on Amazon its a great value where it provides the actual capacity output equal to other more expensive batteries labeled at around 14000 mAh. With a high output efficiency, 4A of total combined charging current, triple output, and motion activated 10-segment led indicator - I highly recommend it!

Someone just pointed out to me Anker has back 2 school sale, with Astro 3 now for $45.99. Here is a link: http://www.ianker.com/adpage.php?act=us
I also been asked if Smart port will charge iPad 4 at full 2.4A speed. I'm checking into this and will post an update as soon as I find out.
I got an anker too, but the e4. Seems like i can only reach 1.8A when i'm using the cable provided by Anker and not the Sammy OEM cable..

If you referring to 1.8A per Galaxy Charging Current app, that's an approximation anyway. Unless if you are rooted and using something else where in an identical setup where you exchange cables and see 1.8A in one case and 2.0A in another case?
Looks great. I would buy it in a second, if it was not so thick. I would not mind a longer wider power bank. A power bank that was 5.7 *4.5*.6 inches would have roughly the same volume as the 2nd generation Astro 3. In other words, the same thickness as the Astro 3E.
PS The volume of the Astro 3E is 9.41 versus the Astro 2nd generation at 14.52. The power bank increased in size more than in power. The Astro 2nd generation is 54 percent larger.
What cable are you using for the note 2? Now i'm not getting the 1800mah charge with the anker e4. Ugh.

But it also increase in capacity and efficiency, so you can also look at it as volume per capacity E3 probably had a capacity of around <7k mAh (after 30% de-rating efficiency). With Astro3 you start with 12000 mAh versus 10000 mAh and have at least 80% average efficiency, plus get 3 outputs with one being smart output used for any iCrap including 2.4A iPad 4 (which btw is confirmed). Also, 10% indicator is way cooler. Just imho, a bit of thickness increase is OK because length is a deal breaker for pocket-ability. And yeah, I'm talking about batteries
If you want absolutely the slimmest possible battery, checkout review of Astro Slim3 6000 mAh I just posted here: http://forum.xda-developers.com/showthread.php?t=2388894 - 12mm in thickness, that is insane!!! and you get 80% efficiency as well with a built in micro-usb cable.
Can't buy this thing on Amazon as it seems Anker for whatever reason has had all their products yanked. Anker sells it on Ebay in their Ebay Anker Store as well .....but they want $199.96 for it! They say it's that high because stock is low. Seems strange to me. I would love to know what is up between Anker and Amazon.

I asked them the same question. Apparently something got messed up with US listing of all of their products and they are working with Amazon to fix it. I had someone from Canada asking me questions about Anker, and I see all of their products are listed fine on Amazon in Canada, UK, Germany, and everywhere else internationally. Something got messed up with US listing and I confirmed with Anker they are working as soon as they can with Amazon to fix it.

Just seems strange to me...Amazon is always very good about fixing technical issues and this has been going on for days. In any event none of that justifies charging 200 bucks for the Astro 3 on their Ebay store....low stock or not.
I've never had anything but good experiences with Anker, FWIW.

I agree! But I actually seen someone else do that before. I forgot which product it was, but we had a reply here on XDA to one of the posts jocking they misplaced a decimal point. Then, someone else posted later they just jacked up the price to keep the listing "alive" while they were out of stock and obviously nobody would buy it for the price 100x higher than original. I guess just another trick...

I gotta say, I'm getting a little worried about this Amazon "problem" . . . we're heading into one week with no Anker products on Amazon and I just don't see a messed-up listing taking this long to remedy. I finally got through to customer service today because I need a bluetooth speaker and I wanted to pick up their BT 4.0 speaker before I head on vacation. They have no idea how long this is going to last and the CSR I spoke to said, in so many words, that I might want to purchase my speaker elsewhere. Understand, I informed her I was under a time constraint so that obviously affected her response, but Anker is getting excoriated on their FB page. I hope everything is rectified soon, because my experience with this company has been spectacular.
Thanks for the review. I'm torn between trying to wait for this one to become available again or to bite the bullet and order the old 3 for $5 more.

First of all, I just saw that all the Anker products are back online on Amazon!
But, I also see that Astro 3 (2nd gen) is on back order due to demand. In my opinion, wait until its available. Why buy old technology when you can get unit with a higher capacity, more USB outputs, better efficiency, and new indicator?
... UPDATE... It is sold out on US Amazon, but should be back in stock in 1 week.
In general, and this doesn't refer just to Anker but any other product/vendor I have reviewed. If anybody has a question for a vendor and can't get an answer right away - let me know because I receive review samples directly from their marketing department and can get in touch quicker to get you an answer.
Hi, i'm getting a really slow charge with the Anker battery. Are you rooted and flashed with Perseus? I can't seem to get a 1.8A charge on any power bank. Stock here btw.

Which battery and what usb cable are you using? I'm all stock, not rooted. Either Anker or any other brand I have tested, if they rate output to 2 - I always see 1.8A charging and can confirm it by timing and watching % charge. But I do use either oem usb cable or usb cable from my ue Boom or monoprice cables. No matter how great your battery, the cable will be your bottleneck if its not true 2A cable. Plus I have tested and can confirm that with a number of external batteries if you are charging from "apple" designated port or port rated at 1A - they put some current limiting to keep it capped.

Tried with the cable that came with the phone, stock, sometimes the charge drops to below 1000ma on the 2A port. Tried with a HTC cable. Same issue. Also tried with the cable that came with the anker, same thing. Am using an Anker E4 so i believe their build quality is more or less the same right?
Which monoprice cable are you using? Can you give me a link on amazon? Guaranteed true 2amp cable?

Hi,
I'm seeking for an external battery than can charge my phone two times from 0% to 100%.
I have seen the anker astro slim3 6000mAh, I like it because it is quite powerful and slim, very portable.
http://www.ianker.com/product/79AN7909-BA
In any case I need a quality battery that don't loose charge if not used for a period of time.
In the anker site I read reviews where customers complains about the fact that the battery loose charge if not used just after few days.
I want a battery that stays fully charged for 15 days also if not used, do you know a battery like this?

As I replied to you in N2 thread, hardly any vendor manufacturers their own battery and rather buy and sell it re-branded. And you will also find some bad "apples" in every batch. Anker has thousands of reviews on Amazon, average rating of 4.5-4.75, and is #1 selling external battery brand on amazon with 18-month warranty. I have every single battery they're selling and reviewed them all. Slim2/3 will hold the charge for awhile, and also their latest 2nd gen Astro series is by far superior to all of their previous models. If you want something portable, 2nd gen Astro will be great with 6000 mAh, or you can go to a bigger double output Astro 2 with 9000 mAh, or triple output Astro 3 with 12000 mAh. Slim 3 is their latest slimmest one which I just checked on Amazon is out of stock due to popularity. I still use Slim 2 and 3 and always encourage my wife to carry it with her in the purse to use when her phone goes down.

Have you ever tried to charge your astro and leave it for 10 days? What are the charge after 10 days?

I will wait. I think that very few people will use the battery pack every day, but as me, they would carry the battery pack just in case is needed.
If it discharge after three days it will be unuseful for most people.

Since I had both Slim 2 and 3 fully charged since yesterday, it will be a good test to let you know how long it will take for any leakage voltage.
Btw, I do realize you are on a mission (after reading one comment out of thousands for all the batteries they sell?!?, not to mention tenths of thousands of other positive comments never left by others because people usually like to complain on-line rather then praise), but just speaking from a personal experience of reviewing over a hundred of accessories just in the last half a year or so - I research every product and company before I approach them asking for samples to review. So for a company to be #1 seller on amazon with thousands of 4.75 star reviews while offering 18-months warranty - simply means they have the best product which people like, and overall its a good working product with a decent quality control. If there is a problem with a design of a product - every single piece will fail. If there is a problem with a bad production batch - everything will be replaced under warranty. If there is a massive failure of products - company will go out of business replacing a lot of faulty products under warranty. Its a common sense. When it comes to electronic products, any company that claims 100% yield is lying, especially if you contract other companies to manufacturer for you or you license other products and sell under re-branded name.
Btw, a simple question. Considering 18-months warranty and hassle free return from amazon (depending on a country where you live), why wouldn't you just buy this $30 battery to try it out yourself and if it doesn't work write your negative comment about it? Should be simple enough.
My advice for you
In your case, I would suggest you to get a larger capacity charger that can charge 3 times your phone. Any charger is gonna lose the power even if you put it aside for a while. I have bought the Anker slim as you did before and I am happy with it. But since I'm getting more electronic devices, I require one with much more juice. My friend once showed me his RavPower 10400mAh and I checked that it has a reasonably price for me. Compared with Anker, I would be even more willing to have another charger from RavPower as they've a cheaper price but even larger capacity.

I abandoned the idea of buying an anker slim, the output of the slim version is 1A and I want 2A at least.
It will take forever to charge a phone with a 1A output.
For this reason I can choose between this:
Anker 2nd gen Astro 2 9000mAh 2A output
Anker Astro 3E 10000mAh 3.1A output
RAVPower 10400mAh 2A output.
can't understand why Anker sells the 2nd gen as something new while the 3E has more features and is cheaper.

Slim 3 charges my Note 2 at 2A charging speed. Doesn't matter what they put on the label lol!!!
All of their batteries will output 2A if your phone can charge at that speed. Regarding capacity versus value, might as well go with Anker E5: http://www.amazon.com/gp/product/B00D5VAYRU/ - 15000 mAh for $49.99 and includes led flashlight (I reviewed that one as well).
The difference between original Anker products and 2nd gen is that new ones have 80% efficiency while old ones is closer to 70%-75%. Every other external battery out there is close to 70% efficiency. When they tell you capacity on the label, its a capacity of internal 4.7V battery inside. That has to be converted to 5V through usb output and during that conversion typically all ext batteries loose 30% of capacity. 2nd gen Anker has a more efficient circuit which looses only 20%. Plus, 2nd get has 10-led power indicator to give you a more accurate reading of charging or remaining power. Their original stuff and slim, as well as every other vendor out there, uses 4-led indicator which gives you accuracy in 25% increments while 2nd gen gives you 10% increments.
Also, for your information, "NikJe" works for RAVPower. I tested a number of their products and they are all good as well. Nothing against them
BTW, just checked both Slim 2 and Slim 3 since it has been 2 days from charging them up to full, they are still at 100% with all 4 leds fully lit up.

there are many people who says that slim3 charges ipad really slows, this clearly means that the label is correct, it can't charge at 2A, not all devices at least.

iPad uses 2.4A, not 2A. Of course it will not charge iPad at full speed. Anker Astro 1/2/3 2nd gen "smart" output can charge it at 2.4A, the latest iPad at full charging speed.
Gee, you don't give up, uh? Just took these pictures for you.

Using Galaxy Charging current app, here is charging from Slim 2 (Max current number is a rating it charges at, 1800 mA always shown for max 2A rating).
And here is using Slim 3 (I couldn't zoom in to display with the whole battery shown):
I don't know what else to tell you, and a bit puzzled with your persistence to paint Anker as inferior product. You can trust my unbiased opinion because I review a lot of batteries, gadgets, accessories, etc. I do that as part time hobby, and as you can see from my post and "thanks" stats people trust my opinion. I'm telling you how it is, and include pictures to back up my write ups. If you don't believe me, it's your choice to buy something else or to buy any of the products I review and come back with your own reply-review to let everybody know if you agree or disagree with my write up.

hey I don't persist in paint anker as inferior I say what they write on their site.
http://www.ianker.com/product/79AN7909-BA#ptop
on their site they wrote that anker small 3 has two 1A ports. if they are wrong in writing specs on the official site also is not my problem in painting anker as inferior.

I wonder if its for safety reason? I know they have over-current and over-voltage protection built in. With slim design you have less air circulation inside of the case to cool down electrical components. With other thicker cases it will run cooler. But either way, it's definitely capable of charging it at high speed.

Hi,
I'm seeking for an external battery than can charge my phone two times from 0% to 100%.
I have seen the anker astro slim3 6000mAh, I like it because it is quite powerful and slim, very portable.
http://www.ianker.com/product/79AN7909-BA
In any case I need a quality battery that don't loose charge if not used for a period of time.
In the anker site I read reviews where customers complains about the fact that the battery loose charge if not used just after few days.
I want a battery that stays fully charged for 15 days also if not used, do you know a battery like this?
Click to expand...
Click to collapse
Is there even such a battery that can produce these results?
It has been 10 days since I charged Slim 2 and Slim 3 to full charge. Just checked their status and each one has 3 leds lit up which means it still has charge of anywhere between 75% and 85%. This is pure standby time with an exception of one time brief use of each just to check charging current. I will post an update in a few weeks again, I'm sure both will still have some juice left
i have galaxy s2 oem charger and galaxy s4 oem charger the galaxy s4 charger is 4 time faster than the galaxy s2 charger i don't know why !!

What is a current rating on each? S4 charger will have 2A (2000 mA) versus S2 being probably at least 1A or slower, not to mention S2 is an older one and they get de-rated after awhile. If your phone can charger at 2A rate (like Note 2 or S4 or Note 3) it will charge at full speed using 2A charger, but if you use 1A charger it will charge at 1/2 speed. If you plug it to USB port of laptop which can only supply 500mA, it will charge at 1/4 speed.
Hi,
I've been browsing for a portable charger that's worth the price, and I think I might have found the one.
Packed with 10000 mAH, the EasyAcc charger coming in at $26.99 is an incredible deal.
Does anyone have any experience with this charger? How is it compared to the reputable Anker portable chargers? What's the efficiency level?
http://www.amazon.com/EasyAcc®-Bril...7501&sr=8-6&keywords=easyacc+portable+charger
Thanks for your help. :highfive:
It may be rated at 10000mah but who knows what the actual ratings are. I've taken apart an anker charger and the batteries they had actually added up to their advertised ratings.
Then there is also the question of how long it will work for, I know anker has a warranty that is close to 1 year that will cover stuff like reduced battery life etc..

Thank you for you input.
See, that's the thing. The price is incredible, but I'm not so sure if it'll last as long as Anker's chargers.

That price isn't that incredible. Here's a link to a RAVPower 8400mAh pack. They also make a 14000 for ten bucks more. I have owned there 8400 pack for about 4 months now and can vouch for it. Them and Anker is who I would stick with.

That one seems a bit too big to fit in the pocket comfortably. I personally have this one and it's pretty good (http://www.amazon.com/5600mAh-Porta...qid=1393834261&sr=8-13&keywords=anker+charger)
From experience, there is no shortcut to buying lithium batteries for a cheaper price and still getting the average ratings for it's price. You really get what you pay for with lithium batteries, unless you have a discount.
This thread should really be in accessories, not Q&A...

i have 8400 mah rawpower really good
I have one 5000mAh from EasyAcc (with fast charge and a micro usb cable built in).
It does have about the same capacity as advertised. Their service was pretty good too.
