The Mighty Mouse ChargerSep 26, 2011
By Andre Frederick
"Sammy G Series"
I never used it to charge my phone from 35% yet. I have been using it at work around lunch time when the battery level drops to 84%. I am using this portable charger with my Samsung Epic 4G Touch (Samsung Galaxy S II). I call it "The Mighty Mouse Charger" because it is small, very portable but it is powerful at 5600mAH. The price is nice. I showed it to people they thought it cost more than the $49 I paid for it.
This portable charger charges at the same rate as the AC charger that comes with the phone. I can take this charger everywhere I go, it can be placed in a pants pocket with a lot of room to spare. The Samsung Epic 4G Touch has a battery life of 12 to 13 for medium use. I am a heavy user, I use the internet, Netflix, play games/music. Netflix alone can drain your phone battery pretty fast if you watch a more for one hour. I am still testing it out. You have to charge it for four to five hours the first time you get it. After that it should last 3 to 4 days before you have to charge it again.
This Anker Power Bank charger really comes in handy. I highly recommend it. Oh I had the New Trent iCruiser IMP1000 11000mAh External Battery Pack. It is 11,00mAh but it was too bulky too carry around without a backpack. I use to carry it in a hard drive case that had a belt loop. I sold it and got this one.

5600mAh?? More like 2300mAh. (READ THE UPDATE AS WELL)Mar 07, 2012
By Abba fan
I've done an extensive research on this product before buying it. I've also read many feedbacks here.
I purchased this item along with Anker's 1700 mAh battery for Droid Incredible.
Now, if you do simple math and consider this product to fully supply 5600 mAh to your battery you will see that I'm suppose to be able to fully charge my phone 3 times with this charger; 1700+1700+1700=5100 and the charger is still suppose to have 500 mAh left. That's after I fully charge the charger using the AC power adapter.
However, when my phone has a few percents of battery left and I connect this charger to it, it takes the charger 2 and at times 3 (out of 4) blue lights to charge up my phone. Be advised that before I do so I fully charge the charger using the power adapter supplied and while it's charging my phone I'm NOT using my phone.
When my phone discharges almost completely and it's time to charge it up again, the charger wouldn't provide the full charge because it has only 1-2 blue lights left after the previous charge. It doesn't make sense. How come simple math doesn't apply here? The charger can't even provide 2 full charging cycles. However, it take about 5-6 hours to fully charge it up. I don't understand this.
Besides, the charger came with no instructions. I mean, you don't have to have a PhD to figure out how it works, but at least some hints on how this device is suppose to work properly would've been appreciated.
By the time of writing this I have fully discharged the charger twice thinking that maybe it should take a few full (dis)charging cycles in order for it to perform at its advertised (5600mAh) level just like with many phone batteries but again there were no instructions with it so I don't know. Puzzled and disappointed. If someone could give me some hints I'd be greatly appreciative.
UPDATE, APRIL 13. HTC REZOUND with 1620 mAh battery.
Initially I gave this product 2 stars. I am adding 1 star for the exceptional service of the seller. They offered me a new replacement and I received it in 2-3 days after they got the bad unit from me.
I am adding another star for the usefulness of the product. If it's fully charged (or even if not, as long as it's calibrated!), it can really save you if you're away from the wall charger.
I'm adding the fifth star because the replacement unit works as explained to me in the comment to my original review. I wasn't aware of the 30% attrition power thing and therefore I didn't know that in reality this backup battery wouldn't provide 3 full charging cycles to my phone battery. However, I still stand behind what I wrote Laptopmate in my email that when people read the product description and see "5600 mAh" hardly anyone would consider that the attrition power factor here would decrease the actual charging capabilities of this battery. Naturally, people would do a simple calculation and assume that a 1700 mAh battery would be charged 3 times with this external battery. Hopefully, people would read everything that I wrote here so that they are not misled.
As for Laptopmate, I am still strongly suggesting you to mention the attrition power nuance in your description wherever you're selling your backup batteries at from now on. Don't expect that people would be aware of this technical detail. You will save yourselves a lot of time from having to explain the same thing to each dissatisfied customer (and maybe you'll have less returns that way too!).
Other than that, 5 stars.
Also, if Laptopmate doesn't mind, I decided to copy-paste their response to another "dissatisfied" customer as it clearly explains the 30% attrition factor.
"Sorry to hear that this external battery does not satisfy you. The input from AC or laptop to external batteries is 5v, while the output from external batteries to phones is 5.3v. Boosting from 5v to 5.3v and the external battery itself consumes power (about 30%). Therefore, the actual power that can be used to charge other devices is 70% (5600x70%=3920mah). So, this external battery is supposed to be able to charge a 1700mah battery for two times and a little more."
P.S. Don't forget to fully calibrate the external battery! Discharge it completely and charge it up to the fullest. Repeat this step 4-5 times and only then you'll see the usefulness of this product.

Awesome batteryOct 06, 2011
By Phil45
While the Anker battery may not be the most powerful battery in existence, it has plenty enough power for my hungry Galaxy S2. The battery is nice and small and very portable. It's so easy to carry that I always have it with me. Its weight isn't enough to become an issue either. It fits nicely in my pants, hoodie or jacket pockets without causing any discomfort due to its rounded edges. It is the perfect balance of physical size and power. Cool that it has a led light too, but whatever. The only possible way to make this product better is to make it double as a small bluetooth control pad as well for playing games on my phone (like a simple NES controller). If Anker made such a device I would easily pay $100 for it.

Pleasantly SurprisedOct 27, 2011
By phljw
This is better than I expected. The charger works fine with my LG Ally. So far it has given at least 3X charging capacity to the internal battery. It fits nicely in my my pocket and is a must for battery hogging smart phone apps.
