Anker 2nd Gen Astro3 12000mAh External Battery Charger with
PowerIQ™ Technology

Features

Anker

PowerIQ™: Full Speed Charging. Every Device, Every Time

Not all charging ports are created equal. Standard ports only charge Apple OR Android devices at full speed. Our solution? Triple smart port, powered by PowerIQ™ technology, intelligently identifies your device and speaks the language it needs for full speed charging. Coupled with an industry-leading 4-amp output, you can charge multiple devices all at full speed.


Anker


Packed with Power

We figure, the more power, the better. Packed with 12000mAh of juice, and featuring an energy efficiency rate 10% above previous generation Astros and many current standard alternatives, the new Astro3 charges the iPhone six times and large-capacity phones like the Galaxy S4 almost four times.


Anker

Double Take

Chic and minimalistic, the new Astro3 may feel reserved at first. But, a friendly "shake" reveals its warm inner light to display the power level or begin your charge. Generous, cool, and delightfully intuitive, the new Astro3 is perfect for your next adventure, or just the daily grind.



For Optimal Use

  • - For simultaneous, max-speed charging of your Astro and other devices, check out Anker's new 25W 5-Port Wall Charger.
  • - To ensure complete safety and best performance, we strongly recommend using your device's original cable, a third-party certified cable (such as MFI) or our included cable.
  • - Compatible with all Apple and Android smartphones, tablets and other USB-charged devices. The iPod Nano, Asus tablets (not include the Nexus 7), the LG G2 and some GPS and Bluetooth devices are not supported.

4 out of 5 eggsAmazing battery

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.

5 out of 5 eggs

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.

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!
