Feature

Features
Smart charging ports, powered by PowerIQ technology, intelligently identify each connected device and speak its language - guaranteeing the fastest charge time for EVERY device (Max speed of 4 Amps among 3 ports).

12,000 mAh of capacity and an energy efficiency rate 10% above previous generation Astros and many current standard alternatives charges the iPhone six times and large-capacity phones like the Galaxy S4 almost four times.

A "shake" starts a charge or displays the remaining power level. The ultra-low power consumption (100,000 shakes consume less than 1%) 10-LED power meter balances accuracy and aesthetics.

Sturdy construction and matte finish withstand bumps and drops. Grade A cells and premium chips ensure reliability. Input: 5V / 2A; Use a 2A adapter (not included) with the included USB cable for the fastest charging time (9 hours).

Package contents: Anker 2nd Generation Astro3 External Battery, webbed travel bag, micro USB cable, user manual. (Apple adapters and Samsung 30-pin adapter not included)

4 out of 5 eggsAmazing battery

This review is from: [Upgraded Version & All Smart Ports] Anker 2nd Gen Astro3 12000mAh Portable External Battery USB Charger with PowerIQ Technology for for Smartphones and Tablets such as iPhone, Galaxy S5, iPad (Black)

Pros: Charges iPhones and Samsung Galaxies extremely fast! It's lightweight enough to carry around in a backpack, if you're in school or travelling. The interface is basic. Shake and it reveals the charge level.

Cons: It's such a simple device there's no way to "reboot" it. This causes an issue because it cannot charge and discharge simultaneously. The first one I received had to be returned because the middle USB discharge port hosed up and was stuck in "discharging" mode despite nothing being plugged in. This made it impossible to recharge the battery itself. The replacement has worked flawlessly though, so that issue cost it an egg.

Other Thoughts: Despite the issue I had, I would definitely recommend this product and would buy it again.

This review is from: [Upgraded Version & All Smart Ports] Anker 2nd Gen Astro3 12000mAh Portable External Battery USB Charger with PowerIQ Technology for for Smartphones and Tablets such as iPhone, Galaxy S5, iPad (Black)

Pros: charges devices quickly and holds charge for a long time

Cons: takes 10-12 hours to charge the battery, but it holds the charge a long time.

Other Thoughts: will charge my galaxy s3 about 6 times on a single charge. haven't charged the ipad or note yet, but read somewhere that it will charge tablets only once per charge.

5 out of 5 eggsBOOM.

This review is from: [Upgraded Version & All Smart Ports] Anker 2nd Gen Astro3 12000mAh Portable External Battery USB Charger with PowerIQ Technology for for Smartphones and Tablets such as iPhone, Galaxy S5, iPad (Black)

Pros: Charges the device as fast as possible. The smart charge is awesome. I had previously purchased a ravpower and had to replace twice before i gave up and went with quality and I'm glad i did. The carrying bag is awesome as well. The light is super cool. The way you jiggle it to charge is instant street cred. Whats not to love?

Cons: I have not found a con yet.

Other Thoughts: Learn from my mistake... don't try to save a couple bucks and go with cheap products (ravpower), go with quality (anker), you wont regret it!
