The all-new 2nd generation Anker Astro2 recasts the possibilities of mobile power. Keep multiple gadgets powered up better than ever, whatever your adventure.
Astro2 9000mAh

Packed with Power

We figure, the more power, the better. Packed with 9000mAh of juice, and featuring an energy efficiency rate 10% higher than the previous generation, the new Astro2 charges the iPhone four to five times and large-capacity phones like the Galaxy S4 almost three times. Keep multiple devices going yourself, and still have juice left to share.

The Faster the Better

Waiting was never fun, was it? That’s why we created the new Astro2 with a smart port that detects USB pin signals to identify your device – whether Apple, Android, or even the Samsung Galaxy Tab – and charge it at full speed. With an additional port, no need to wait in line either.

Double Take

Chic and minimalistic, the new Astro2 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 Astro2 is perfect for your next adventure, or just the daily grind.

4 out of 5 eggsAnker Support

Pros: Works great. Love having extra juice on the move.

Cons: Had one completely die.

Other Thoughts: Anker has stepped up it's game in the support department. I got a replacement direct from Anker, despite my purchase on Newegg instead of Amzon.

1 out of 5 eggsStay away! Do not order

Pros: When it works, it works.

Cons: Support is terrible. Anker refuses to support their products unless sold on another popular website (a mazon). Phone support said they have NO WARRANTY if not purchased from that other online retailer. What sort of company doesn't stand behind their products?

I've had this charger for less than 3 months, charged and discharged the thing maybe 10-20 times, and now nothing. No lights when shaken, does not charge any device either port with any cable, and cannot be charged using any of my chargers or cables. Thing is a paperweight and Anker doesn't care about their customers enough to replace their faulty product. STAY AWAY!

3 out of 5 eggsBeware, a newer version is available

Pros: Works great, can charge my nook HD and galaxy note on one full charge. The smart port is awesome; no more using a special charger or special ports for Android, iProduct, tablets, etc. It just works.

Cons: Only one port is the smart port. Anker has a newer version, with the same model number. The one newegg is selling is an older version. If the second smart port is important to you, check other online retailers.

Other Thoughts: The current gen model with two smart ports would be as perfect as can be.
