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



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.


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.


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.

2 out of 5 eggsStatus light is incredibly annoying

Pros: Lots of capacity
Lots of smart ports

Cons: The slightest movement turns on that stupid light. You don't have to "shake it", merely tapping it lightly turns it on

Other Thoughts: I thought the light wouldn't matter, and it doesn't seem to discharge it, but when it is in my case with everything else, it seems to always be on when I merely reach in to grab something else and is really distracting. They could have required something more to turn it on, or even put a switch to disable it or something.

5 out of 5 eggsGreat Power Bank

Pros: Charges my Galaxy S3 from dead to 100% in under an hour. Charging with a 4A charger which I bought to charge phones and tablets will do the job in about 4hrs. Off of my phone charger, overnight. Considering the capacity, I don't expect any less.

Cons: Supplied with only one cable.

Other Thoughts: I have another brand power bank that can be found here and it was supplied with 2 compact coil cables. I use one of those instead of the supplied cable and It makes a very tidy package for traveling. I asked my daughters if they wanted one too and they declined the offer until they saw how well it works. I had to order myself another. Would I buy again. Yes without a doubt. I have been able to get 4 complete charges on my S3 with about 20% power left.

4 out of 5 eggsGreat Power Bank

Pros: Lots of power! I was able to charge my iPhone 5s four times from empty to full... and there was still some juice left in the power bank.

Cons: Does not come with an AC plug. To charge the bank, you will need to find a 2.1a AC adapter. A 1.0a adapter will not charge it.

1 out of 5 eggsnot that good

Pros: 3 smart USB ports.
Newegg RMA service is EXCELLENT!

Cons: not true 12000mAh. I tried it to give my iPad 3 (11560mAh) a full charge but it only got to 70% before it quit.
Takes long time to charge, with the IPAD charger (2.1A).
Bulky and heavy.

Other Thoughts: It is worse than I expected. 3 USB ports is nice, but giving the true capacity is just over 7000mAh I wouldn't expect to charge three smart items at the sametime.
The item is also bulky and heavy. I wouldn't want to bring it for a tour in the city. Then the item is not robust enough for a hiking trip. So what it is good for. To me the circle LED indicator is also a nuisance. A tiny move will turn it on. If it is not 100% full it will goes down light by light (the whole circle contains 10 smaller LEDs) to where the capacity is, and it takes a few seconds to know how much capacity it has left.
I am going to try something else, for this price there are many other better options.

1 out of 5 eggsCharging Takes Too Long

Pros: Nice Design and convenient.. once this is charged..

Cons: The major concern I have is that - The power bank takes more than 12 hours to charge itself with a 5.1V/2.1A charger (as per the instruction manual it should only take 6 hours). Not sure the one I just bought is a defective unit but the charging time is annoying
