41 of 41 people found the following review helpful Well built and attractive quality battery pack., January 19, 2012 By  r.garcia - See all my reviews This review is from: Anker� Astro2 Dual USB Output 8400mAh External Battery Pack and Charger with Flashlight for iPhone 4 4S 3GS 3G, iPad (1-3), iPod; Android Smartphones: Samsung Galaxy S3 S III I9300, Galaxy S2 S II I9100, Galaxy Nexus, Galaxy Note / HTC Sensation, One X, One S, Thunderbolt, EVO / Nokia N9 lumia 900 800 / Motorola Triumph, Droid 3 X X2 Bionic Razr; PSP; GoPro; MP3 MP4 MP5 Players and More Mobile Devices - [2 USB Output 5V 1A / 2A, 18 Months Warranty] (Wireless Phone Accessory) After using this battery pack for about a week, I make the following observations, in order of personal significance: 1. Build quality: The battery pack feels, in a word, solid. There is no flimsy plastic deflection if you press on it and no creaky or uneven seams. 2. Looks: The pack looks great. Yes it is a fingerprint magnet, but it also wipes cleanly to a beautiful gloss to match most smartphones out there. 3. Utility: Very versatile. One port for smartphone and most usb powered gadgets, the other higher amperage port for more power hungry devices, like tablets. I've even used this to charge AA batteries with a usb AA charger. There's nothing I've tried that this won't charge. Also has a built in led "flashlight," but more on this later. 4. Convenience: This pack will charge easily with any usb charger. Standard micro usb connector means you won't have to go searching for a special cable to plug this in and charge it. This pack...

In fact there are few 12V-5V converters that will do that. This battery pack has both the capacity and current output (2A) to charge pretty much anything that takes 5V - phones or tablets. I like the charge indicators and also the flashlight, for emergencies. The instructions were in both chinese and english - and they were adequate. I tried the battery on an iPhone, Kindle Fire and HP Touchpad. All charged correctly. Note that there are two USB outputs - one is limited to 0.6A and the other to 2A. Use the higher current for tablets.

Ta "NT" (Tacoma, WA) - See all my reviews    Amazon Verified Purchase( What's this?) This review is from: Anker� Astro2 Dual USB Output 8400mAh External Battery Pack and Charger with Flashlight for iPhone 4 4S 3GS 3G, iPad (1-3), iPod; Android Smartphones: Samsung Galaxy S3 S III I9300, Galaxy S2 S II I9100, Galaxy Nexus, Galaxy Note / HTC Sensation, One X, One S, Thunderbolt, EVO / Nokia N9 lumia 900 800 / Motorola Triumph, Droid 3 X X2 Bionic Razr; PSP; GoPro; MP3 MP4 MP5 Players and More Mobile Devices - [2 USB Output 5V 1A / 2A, 18 Months Warranty] (Wireless Phone Accessory) Here is my unbiased review of Anker Astro 2 8400mAh external battery pack: Charge Efficiency: Its rated at 8,400mAh as it's capacity. The lithium ion battery may have that capacity but it's ability to charge other devices isn't so hot. I understand the Anker power bank needs power of its own to operate and conversion from 3.7v to 5.0v takes energy. I wasn't expecting 100% of 8,400mAh to fully charge into other devices totaling up to 8,400mAh. But I was expecting it to be efficient. I did 5 charge and discharge cycles (though it may not be necessary on lithium batteries but I did it anyways to calibrate it) then I went on with my test to see how much it can charge my Kindle Fire, HTC Evo 3d, HTC Evo, Kindle reader, and portable speaker. Yes, the devices I were charging were completely off to preserve energy for charging only instead of also powering it on. The first charge cycle it totaled 5,425mAh (64% efficiency), 2nd is 6,032mAh (71.81% ), and 3rd is 5,280mAh...
