External Rechargeable Battery?

Anybody know a good portable charging block that will put out nearly 1A? And holds a good charge.. not looking for anything too expensive and the extended battery isn't that great so I'd rather have a portable charger

I'm interested in these from monoprice: http://www.monoprice.com/products/subdepartment.asp?c_id=108&cp_id=10833&cs_id=1083311
I've bought a lot of other stuff from monoprice and always been pleased. You should get one and let us know how you like it!

What is your power bank?

Hi All! So this is my first time starting a new thread so I hope I'm doing this right. I couldn't really find a thread specifically for battery banks or battery backups so I thought I'd start one.
I was wondering what is everyone's method of backing up/recharging your battery for your cellphones? For me, the battery that comes with my phone is enough to get me through the day usually and I just charge it every night while I sleep. If I go on trips, I use the Rav Power 10000 mah battery bank. I find this a bit bulky but it works great and lasts many charges before I have to recharge again.
Everyone's taste and preferences are different so I'm seeing what other options are out there that may be lighter in weight. I'm thinking of getting their smaller one, the 5200 mah, and have this in my backpack or car for just in case.
Any mini reviews of what you have would be great :good:

Wow, cool gadgets, I need to get a bank for just-in-case emergencies. Thanks Currently i use a solar powered charger, which is really slow and somethings doesn't work as desired. Looks similar to this http://www.amazon.com/External-Univ...=8-4&keywords=solar+powered+cellphone+charger

Ive bought one at sunsky from china battery about 4000mah, but it was year before, now there is a better.

I used to have a bank that looked like a GBA SP, with foldable screens. In the screens were two solar panels, which charged the battery of, I think, about 2000mAh or something like that. The thing is now broken though. Still looking for a nice (affordable) replacement

Mine is Anker 5600

I use the Belkin 4000, size similar to a ext HDD and look nice, pocketable too

Charger considerations
Hi,
I need advise for the following:
Charger A (Li-polymer battery) output : 5V, 1A
Charger B (Li-polymer battery) output : 5V, 500mA
Device input: 5V, 750mAH (Li-ion / Li-polymer)
When using Charger A, some people comment that it will limit the current of 750mAH for the device and the device's battery should be fine since both the charger and device are at 5V. However, some people comment that this will shorten the battery life of the device since it will perform a 'quick charge' using 1A.
When using Charger B, some people comment that the device will draw more current than it can deliver and causes it to heat up and reduces the charger's life. However, some people comment that Charger B will extend the battery life of the device since it performs a 'slow charge'.
I also read that USB pins on the charger denotes if the charger is a PC or a dedicated charger. If it is a PC, the device will limit the drawing current. If it is a dedicated charger, the device will draw more current to charge itself.
I am confused as to who is right and which charger should i be using.
Can someone enlighten me ?
Thank you very much.

bought this one from Ebay, has not yet arrived, therefore I cannot tell if its good or not.
but for its price its quite a good bet, 12000mAh for 33 bucks (on sale until tomorrow)

I recommend Anker 5600 is very good for that stuff.

Hi, I use choiix power fort 10Wh http://www.coolermaster-usa.com/product.php?product_id=3001 it have 2700mAh and it's small and looks very nice. It can give one full charge for my SGSIII

I went on a trip this year and searched for a good bank, and this showed up.
http://www.sayes.co/20-powerbank.html
I tried it and it was really good, it has lots of adapters and it's cheap =P

I was able to order a RavPower 5600mAh on sale a while back ago, that was posted on slickdeals. here. I am pretty happy with the performance of the little backup, it defiantly gets the job done. My only complaint is that the body gets scratched up easily.

I was comparing the Ravpower and the Anker 5600 and they both look exactly the same except that both are branded with their logos. So I'm wondering if they're from the same manufacturer. Going to have to do some more research. However my current Ravpower power bank I do have is working great and I love this thing for trips.
I'm also thinking of getting a solar one for my 3day emergency/bug out bag. Thanks for all the suggestions.

Yeah, can someone please let me know if they are the exact same manufactuers, except for the company logos on them? I am deciding between the two. Also, what do you guys think of their 2600maH stick version? Which manufactuer would you go for over the other and why? I am very interested.

I'm using a "Scosche SolBAT II Solar Powered Backup Battery and Charger" which I bought off Amazon for something ridiculous like $15 last year.
I bought it for hiking mostly as an emergency charger. I use a Huawei phone as a GPS out in the wilderness, and the GPS app (Androzic) is quite power intensive. I have also used the same device on an iPhone and an iPod touch. The Huawei phone will receive a full charge from this battery, but the iDevices will only go to around 75%.
The solar cell on the back of the battery isn't all that efficient and will take about two days to charge the internal battery, but having it there gives you more options should an emergency occur while in the wilderness. A half hour charging in full sunlight would provide enough power for a short call or a couple of texts to family or emergency services.
The device comes with suction cups and a small carabiner, so it can be stuck to the inside of your car window or clipped to the back of your rucksack. The device is lighter and smaller than the average smartphone and can be fully charged by USB in about three hours. Interestingly, the device has a LOT of bad reviews on Amazon, so maybe they simply sent me a good one.
I also have a very cheap and nasty handcrank USB charger from dealextreme which can be used to add a bit of juice to the solar battery pack at night or in cloudy weather or can directly charge the phone in an emergency. It's a little flimsy and takes a fair bit of cranking to get enough juice for even one call, but it weighs nothing, cost about $2 and is cheap insurance out in the boonies.
My list of power equipment for the phone/GPS and the iPod Touch for a multi-day walk are as follows:
Short Micro USB cable x 1
iPod USB cable x 1
Scosche SolBAT II battery/charger with alloy carabiner
DX hand crank battery charger
Total weight is less than 200 grams

Honestly i went with pricing. I assume if they look the same they are from the same vendors/manufactures but different brand/company. Reviews for both sound very good too. Ravpower had a promo going on a while back and i tend to see them pop up from time to time on slick deals. The stick might give you one charge but since it looks smaller than the rest, it may be the easiest and lightest to carry around. I say get a decent sized one. Anywhere between 5600mah to 10000mah so you can go through a few charges without needing to charge again.

I have a 6600 mAh(well, in my experience it's not true, more like 4-4.5k), but I rarely use it after I bought a tablet with a fullsized usb port in it.

External Battery Pack for my Android device?

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.

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.

Help me to select a portable battery charger for my Galaxy S3 I9300

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.

Anybody use any of these Qi portable power banks?

I'm looking to by a something as the title suggests. I am looking into 3 on Amazon that look good for the price.
First: MOCREO(TM) 10000mAh High Capacity Portable Power Bank http://www.amazon.com/gp/product/B00FRDNLD8/ref=ox_sc_sfl_title_4?ie=UTF8&psc=1&smid=A1J7O7Q2KLU8CQ
Second: Anker 6000mAh High-Capacity Qi-Enabled
http://www.amazon.com/gp/product/B00EST8MRM/ref=ox_sc_sfl_title_5?ie=UTF8&psc=1&smid=A294P4X9EWVXLJ
Third: LuguLake 6000mAh Qi - Enabled Inductive Wireless Charger Charging Pad
http://www.amazon.com/gp/product/B00CY4SG10/ref=ox_sc_sfl_title_9?ie=UTF8&psc=1&smid=AOHIKKIFQW3GG
If any of you guys used any of these, what is your experience with it? Also if you could provide info on whether or not the Nexus 5 will stick on there until a certain angle or will it slip right off even if you move the charger around. Asking this because i'll be using it in the car also.
Thanks

I have the Lugulake one. It's good, works well, charges the phone in a very similar time to the wall charger and has a decent grip on the phone, not sure how good it'd be in car tho. But.... I also want one of these which I'll be ordering soon for the car -

I think both of those devices are available on Amazon and for under $50. I'm thinking of getting the first one. Vent mount and I can use my SGS3 with it.

I have one I got on ebay that is 10,000mah and looks identical to the first link. (http://www.ebay.com/itm/141047804367) It cost $37 (looks like the price dropped a little since) and so far I'm very happy with it, though I've only used it a bit when traveling. It does take a while to charge since 10,000mah on a 1A charger is 10hrs. I haven't really carefully tested its functionality though. I wonder if its current discharge limit is lower than it says, though, since I noticed when I had my n5 plugged into it the 2.1A port and under heavy use (games) the phone battery didnt charge, it only discharged slower... I'll have to test more.
