2x Battery + charger 2000mah($13.00)

Gonna try them out...not sure what i'm gonna get but for 13 bucks worth a try
http://cgi.ebay.com/2x-2000mAh-Batt...330459330057?pt=PDA_Accessories#ht_4942wt_911

Highly doubtful 2000ma batteries, probably 1500ma batteries that are really 1300ma. Tutoit on ebay I have 2x1500ma batteries for a 9.98$ shipped with a charger, I would get that instead.

yeah, either get the 2 1500s and the charger for 11 50

I was just looking at this... seems like a great idea... the extra charger allows you to keep a second battery charged without using the EVO to do it. Even if it's really a lower rated battery... still a good deal.
Did you try it?

I have a set of the 1500 mah batteries with the charger as was posted above, and I have no problem with them. I use my OEM battery most of the time, but sometimes it is handy to have some fully-charged back-ups. Honestly, I don't see much of a difference between what my OEM battery lasts and the knock-offs. For the price, you can't beat it.

so how are the batteries?

normally i would stay way from cheap Chinese crap on eBay, but with what i read here on the xda boards in regaurds t othe ok qualitybeing good enough that they might work out, so i ordered 2x1850 plus charger from ebay. i dont have time to do any real testing but i can say that:
1 not having to charge the battery from the phone is nice
2 i always have one on the charger, one in my pocket and one in the phone.
3 charging in the base seems to get me a better charge
4 i cant tell a difference between oem and knock offs, although you would think that the 1800's would last longer than the 1500oem but we know how that knock off crap goes. in my book if they are the same as oem, regardless as to what they claim and dont require a bigger back plate, then i guess that's good enough.

The 2 from tutoit or what ever the sellers name is work great last as long or longer then my stock battery. The charger also gives a better charge to the batteries then I get through my phone I'm talking extra hours when I charge with it.

I got this and it's a good deal for the price.
The batteries aren't as good as oem. Probably last 75-80% as long.
The charger works well though and it's nice to have a couple extra batts laying around. I've only cycled them 4 or 5 times so I suppose the life could improve...time will tell.

I Have a number of Minor issues with mine. Must of gotten a bad set.
1) USB port on the charger does not output enough juice to charge the phone (Accually Locks it up until I unplug it)
2) Charger seems hit or miss on recharging the Stock Battery. I've left it plugged in all night and come back to ~20% charge when I pop it in a number of times
3) Random Screen cut off when charging the Replacements IN the phone.
So I only charge the Ghetto batteries in the charger provided.
That being said, I STILL think it's a great deal and more than happy with my purchase. I have 2 spare batteries for my phone (Or the wifes CDMA Hero) and a way to charge one w/o having to leave my phone behind (I don't have to babysit my phone for a charge, If someone walks out of the poker room or party with my charger and battery it's no big deal) The 2 China batts. are just emergency tanks, The Red one gets put back in as soon as I get home.

Best Purchase at twice the price.
Don't wait press the BUY NOW!!!!
Loved the first set so much that I purchased a second set 2 weeks later. I keep 1 set at work and 1 set at home. I always carrying a fully charged battery in plastic bag in my pocket. I love the EVO but hate the battery life. The first month I owned the EVO was hell for me having to carry a power charger and cable everywhere. I hated having to plug my phone in every time I found a power outlet worried if I didn't I may find myself without a phone when I needed it or having to fight everyone at the airports for power outlets. Now when I'm low on juice, I just switch batteries.... BUY NOW you'll never regret it....

I purchased 2 3500 batteries with new backs on e-bay for $22 and change. They work great I can go for over a day with fairly heavy usage.
Only minor problem was that with the phone thicker my silicone case doesn't fit as good. Extra weight no problem.

Yeah one thing I have learned from buying these types of batteries and charger is that they don't like to charge the OEM batteries but charge the cheapo ones just fine. I've noticed it on alot of things not just phone batteries.

buy it for the charger
i bought a 2000mAh that turned out to be a 900mAh so i would only buy it for the charger.

I wouldn't recommend the 2 x 1500 batteries plus charters the 1500's seem like a 1300 or a little less I would say try get the 1800 one from eBay they have a lot of auctions for them so all you gotta do is be patient and try to get for cheap that's what I'm tryin to do

Just ordered one of the 1800mah.. will see how this works out!

$15 for 3 batteries + charger. Too good to be true?

I ordered this... http://www.ebay.com/itm/170731777597?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 Its a 3 battery + solo battery charger combo, cost $15 no tax.. no shipping. Took about 2 weeks to get and every battery works flawlessly.
They all come with 66%charge. The charger even charges my stock battery. All batteries have a cut off switch built in like the original that doesn't allow overcharging. The charger has a led that is red when charging and blue when charged. I have not noticed any difference in battery life when I switch to another battery. At night I can charge one in my phone and one in my new charger. I take two with me and just leave em In my car or my e5 easy case. Never run out of battery, don't have to be plugged in constantly, I use my phone heavily and some days I need 3 full charges. Even if i use 3 batteries in one day, by the time i finish the 3rd the first is charged. I only ever have to charge 2 at night when I'm asleep. The next day I wake up with 4 fully charged (3 spare + 1 original) but iv never used all 4 in one day.
I have tried everything I can to get the batteries to fail, overclocking @ 1700 using them from 100%-0% without stop and even overclocking while plugged in. I cannot get the battery to fail.
Ill keep you updated if anything changes (I know even with the review some are skeptical) but for 2 weeks of heavy use, I use my note allll day Im a stay at home father/student, none of the batteries have failed.
I hope this was helpfull.

False. They charge just fine. But, faster on the wall. Actually they charge faster on the wall than my original with supplied usb charger. Whoever made your girlfriend's phone might have mentioned that in the information though. Pays to read thoroughly. As I've said before. No problems. I cant even tell what battery I have in my phone, I should mark them... because they all work the same.

That's brutal! You ought to make a thread and warn people so we don't make the same mistake bro. This is what it's all about. Hope these batteries work as good for you as they did for me.

I have this set.
The batteries definitely work and they don't 'fail' but they are without question far worse than the stock samsung battery. I'm okay with that, considering how cheap they are.
- Frank

these batteries are not secure enough to be bought - the worst thing that could happen is they might explode. They are not cheap for nothing!! I've read a couple of articles about counterfeit battery catching fire/exploding and in my opinion, it's preferable to add some more cash and buy a genuine battery, than those fake ones. Better be safe than sorry...Just my 2cents...

Don't know about you...
But I would never joke with battery
Sent from my Galaxy Note

I got the same batteries as OP and they work, but definitely don't have the same capacity as OEM. I'd guesstimate 60%-70% capacity. The cheapo white ones on Ebay are a little better than the blacks, but still definitely reduced capacity compared to OEM. Regardless, it's a great deal for the price.

i bought similar batteries for my SGS2 and they worked great
i already ordered a similar combo (3 Batteries + 1 charger) for my note
waiting for it to arrive

It was pretty fast shipping. for 10bux, Its pretty good deal however you look at it.

Got the 3batteries and charger deal as well. No problems. My only complaint is the universal charger that came with it. It takes FOREVER to charge the batteries. I charged them faster just switching them in the phone. I'm sure there are better wall chargers out there though.

Not a good sign for Apple's famed quality if the stock battery died in 1,5 years (assuming she got her IPhone on release). After more than two years the battery in my good old i8910 is still running about 2-3 days with moderate usage.

Thanks Op for the link. They are cheaper now.

Never had much luck with other manufacturer's replacements
I'm delighted that I can now buy a replacement Samsung battery - just ordered from Mobile Fun

QI Charger/Power Bank

I wanted to get QI charger w/ my Nexus and ended up getting one that included a 10,000 mAh powerbank for basically the same price.
I thought it was going to feel pretty cheap, but to my surprise it seems like its pretty good quality. For 40 bucks for both a QI and a power bank in one it's pretty kick arse! So be forewarned the "IN STOCK" status is BS it ships from China so don't expect within a week; I think I got mine in 3 weeks.
Also the instructions are horrendous, not sure who translated it but its actually comedy. I think says something like... "Use it if it bulges, smells or smokes." (instead of dont) and has FAQ's that have no questions. Literally every line in the instructions does not make sense.
So you can use this as a normal QI charger. As a powerbank you can use QI or plug it in through the USB ports (2) which makes more sense so you dont have 30% power loss as with QI. Powerbank is same shape as phone just about twice as thick and slightly larger width and length. Finished material is smooth so if you have a hard plastic case it may easily slide off or not become centered well enough to charge. I have a case no issues charging through the case. It does also get a full charge and it does not get my phone more than warm (same as wall charger).

*not much but you can save a little here:
forgot to mention you can Save 5% on Qi Wireless Charger Transmitter 10000mAh Mobile Power Bank(ASIN:B00FS1NTMW) when you purchase 1 or more Qi Standard Wireless Charging Receiver offered by Docooler. Enter code 3VYHPR39 at checkout.
Enter code 3VYHPR39

I'd be very interested in a test to see what the actual capacity of this is. Im always wary with a no name brand battery from China because they tend to always overstate their battery capacities. Wish there were some reviews, but I might give it a go anyway to test it out myself.

Looks interesting, but the lack of reviews make it sound dubious

Its weird how almost all of the qi power banks on amazon have no reviews. Seems like something everyone should have. Ridiculously useful. I am wondering why the one posted above is a good 25% cheaper than all the others of the same 10,000 mah capacity though.
Would absolutely love for the OP to test how many full charges of the Nexus 5 he could get from the device using USB and then Wireless charging, but that would probably take a while. Also OP, when you say that the case is smooth, is it smooth like the soft touch plastic on the back of the Nexus 5 or smooth like the shiny plastic on galaxy phones?

I'm waiting for RavPower Qi Wireless Charging Pad with a built-in 4800mAh battery coming back in stock. It seems like a great fit with my Nexus 5 as I checked a review from WPCentral.

Ordered one
Just ordered one. Will let you guys know when I get it, what it's like!

no problem but may be a few days I'm getting over a day cycle on my nexus so far. I bought it mostly for the QI charger the bank was a bonus/ I will keep a log but try and get full cycles out of it to make it easier.
As far as the smoothness it is more like the shiny plastic on the galaxy phones. My phone has a plastic case it doesn't slide to much but I could see if it got bumped it would move. I had bought a screen protector someone posted that i don't like it's kind of rubbery or tacky feel i was thinking about taking it off and putting it on the charger so it was a little more "grippy".
Give me a few days I'll put up some stats for you

Oh I know, but the ones sold under the badge of Samsung or LG are usually dead on their mah capacity ratings. Not so much for random Chinese brands I havent heard of before.

Amazons having a 50% off deal on battery packs if you buy the RAVpower qi charger. I just picked up the charger and a RAV 8400mAh pack for just over 60 bucks. I've been wanting both for a while now and this deal was just to good to pass up. I do a lot of backpacking and have been debating between a battery pack vs. a solar charger for some time now as well. The pack is actually lighter than any of the solar charges I was looking at. And for 18 bucks was a no brainer.

so here are some stats on this as a power bank not sure how much power loss over a few days is normal but after a full charge of the bank using the cable here is what I came up with:
night one charger started at 51% .49 of the full 2300 mAh nexus 5 battery = 1127 mAh
night two started at 18% .82 = 1886
night three started at 22% .78 = 1794
night four started at 28% .72 = 1656
night five started at 9% died at 32% = 529
______________________________________________________________________
TOTAL mAh= 6992

Interesting. And that is using the cable and not the Qi wireless charging? Its always said that Qi will have around a 30% loss in efficiency, which would make your numbers perfectly in line with what a 10,000 mah battery should do. Of course if you were using a cable it might just be that the low cost of the device translates to a less efficient transfer of energy. Still able to get roughly 3 full charges out of the power bank is pretty awesome.

Yea thats through the cable, I know even turned off there is power loss on rechargeable batteries but I don't know what is normal power degradation equates to in a percentage. I agree though roughly 3 full charges may not be a full 10,000 mAh bank, but at the price even if it equates to a 7000 bank its not bad. Throw in the QI (which is mainly what I bought this for anyway) and this is pretty sweet deal :laugh:
I'll do it again and see what I come up with for round 2

it does shut off once it gets a full charge, using the cable as a powerbank. Never tried QI as a bank doesn't make sense so don't know this way.

Using external powerbanks?

I'm considering buying this powerbank:
http://www.amazon.com/gp/product/B00BQ5KHJW/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A294P4X9EWVXLJ
Many people recommend Anker but what about this model? I plan to use this not every day but for short weekend trips. My father plans to use this for his Sony Xperia Z Ultra.
I hear good things about Ravpower and Xioami (though you have to make sure they're the genuine kind).
Any thoughts?

I've become a bit of an Anker zealot lately and have bought batteries, a mouse, a keyboard and a bluetooth speaker from them. All work incredibly well and easy way beyond what the price suggests (sort of like the OPO).
As for the batteries I have the Astro slim 4500 and the 10k mAh bank and both work as advertised. The capacity on them seems to be lower if you're filling from empty (probably heat related) so if I NEED the batteries to stretch a short camping trip I'll try to do more topping off as time allows.

I love my http://www.amazon.com/Jackery®-Bar-...8&qid=1412378909&sr=1-2&keywords=jackery+5600
I showed it to a friend who also bought the exact some one. Great size and fast charging with pass through.

I use this exact same one, I love it because they offer 3A charging, large mah and fair prices. Very hard to beat.

It depends what you're looking for. The way physics works, you won't get the whole advertised mAh. You'll only get about 70% of it (rest is lost as heat) given that, a 10,000mah battery pack will only provide 7000 to charge which will only charge the one plus from 0-100% twice ONLY if you're charging the phone which while it's off. I'm looking at getting one that will harte the phone 3 times and that also has a a % indication on the battery pack. I've only found one for 15000mah and has the LED % indicator

OnePlus one and AutoPowerON feature seems to be not compatible.
Consider to buy one without AutoPowerOn on plug.

Actually, the OnePlus has a good battery life, and you surely can make it run for 2 days easily with only messaging and internet. Though, I think a 10k mAh should be more than enough for a couple of days. I actually have a 2000 mAh battery only in case when I'm out of home for more than 24h but I've never used it. I'm also using the power Quick Tile and I think with the "energy saving mode" enabled you can last one and a half day easily
Sorry for my approximative english, cheers !

Hello i jist bought a 13000mah powerbank for how long should i charge it for the first time using a 5v 2A charger and it came with 75% charged what should I do?

[Q] Best experiences with external battery backups?

Just ordered a Zenfone 2 to replace my old S3. Love the phone, but hate the non-removable battery. Took the leap anyway because of the price. What are your best recommendations for battery backup units in the ~6000 mAh, ~12000 mAh, and ~20000+ mAh ranges? I figure I can snag a small backup that can fit in a pocket and a larger one I can leave in my car/bag/backpack. Which ones have you guys experienced that are long lasting and charge effectively? Ones that are resilient? Anything to the gimmicky seeming solar charging backup units from the like of ZeroLemon or another producer?

Aukey has a "Quick Charge 2.0" battery pack that should quick charge the phone way faster than any other option out there. Other than that I'd just watch the usual deal forums, etc. to find well reviewed models on sale.
My assumption has always been that tiny solar panels probably take forever to replenish your battery pack, but I can't say I have any firsthand experience.

The Aukey ones work well, I have 2 of them and they quick charge just fine and will give you ~2-2.5 charges depending on your usage while charging.

They are surprisingly cheap! $30.00 on Amazon for a 10,000 mAh version. That looks like a good rec. Do you have any experience with ones in the range of 20-30k mAh?

I would ONLY buy Anker brand. a lot of usb mobile batteries dont have power output to charge a phone that is also in use, and also have a heavy degradation after multiple uses. I was in a jam and bought a second battery at a CVS when i was out of town on business once and left my Anker brand at home, and after 3 uses it no longer could charge my phone faster than i was using it (talking on the phone).

Is the lifespan of Anker brand backups well known to be good? I'm thinking I'll buy two of the same unit so I can quickly swap them out of my bag when they die.

I'm getting the Mi Power Bank...the 10000 mah version can be had for $14 usd. Only downside is you have to wait for the "flash" sale. There will be one tonight at 9 central time(US).

Why don't you guys try the Asus Zenpower. I bought it with my phone for a package deal and looks very solid! Small too.. though its heavy.

I looked at getting one....however Asus wanted to charge $14 for ground shipping....ordered the Mi Power bank earlier....and they charged $5 to ship. With stock in the US, there is no way Asus should be charging that much for ground....Express shouldn't cost that much! Also....I wanted the Mi Band lol

I ended up ordering two of the 13000 mAh and one 6400 mAh backup, all from Anker. They were all Amazon Prime so I got free fast shipping, and they offer their version of Quick Charge so it should be a solid option for me. I'll update with my experience after I've had them for a bit if anyone cares.

Oh I am sorry to hear that man. Did you check eBay? Coz i got mine with the phone. If i deduct the phone price, the zenpower was only $10 plus shipping was free coz it was with the phone anyway. Mi is equally good. I am done with massive brands such as Samsung.. we mostly end up paying for their advertising, marketing and brand name.
