Nice review mate !
Found another review on Tech Junction : Tylt PowerPlant Review.

Good video review, Raul, but NOT a good value for an external battery. This is 5200 mAh battery with a typical 70-75% efficiency which means in reality you only get about 3800 mAh of charging capacity. And on amazon it's priced from various sources for $65-$70 and has less than a hundred reviews. This will be used for only 1 charge with my Note 2 3100mah battery and not even a full charge with my new Nexus 7 tablet. The best value and quality are Anker external batteries with hundreds of 5-star reviews and variety of models like Slim 3 with 6000 mAh battery and built in cable like Tylt and cost $37 or Astro3 2nd gen with 12000 mAh and 3 usb charging ports including smart port that can charge latest iPad at 2.4A and 10-led power indicator with 80% efficiency output all for $49.99.
Sorry, didn't mean to rain on your review, you did a fantastic job with video review. I just review hundreds of accessories here on XDA (check out my sig link), and haven't found anything remotely better in quality, customer support and warranty (18-months warranty), and pricing. RAVPower also has quality external batteries and sometime have great deals under $30 for high capacity batteries, but they don't have as much variety as Anker.

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.

I was looking for a solar charger. I bougth one but it crashed in two days. Therefore I returned it and now I am waiting for another one. In the place I live there are few options

[Q] Help me choose external battery pack

Hi all,
Looking into an external battery pack. Anyone have either of these?
Looking mainly to charge my galaxy s3, ipod touch, galaxy note 10.1, and girlfriends iPhone.
We use our devices alot and usually need some extra power during day.
The more compact the better but wanting at least 10000 mah,so what is yours?

2430 battery gold

I just ordered a used one of these bad boys from Amazon: http://www.amazon.com/dp/B00439G3WS/ref=pe_175190_21431760_3p_M3T1_ST1_dp_1. 16,000mAh battery, microUSB charging input jack, and five USB outputs.

I'm not sure how I'd feel about buying a used battery. Li-ion batteries degrade in capacity no matter what and I'd want to know some details and the current capacity before forking over any money.

Review of Anker Astro 3 (2nd gen) 12000 mAh external battery w/pics!!!

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?

Best external battery.

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.

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.

I would like to understand if it is bad apples or the only users who noticed the problem.
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.

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.
