Anker 2nd Gen Astro Pro2 20000mAh Quad-Port External Battery

60W wall charger - product

Product Description

Tablet & phone compatibility? Universal max-speed charging? Power-packed & portable? The reinvented Astro Pro2 has it all.

Compatibility maximized.

Not all charging ports are created equal. Standard ports only communicate effectively with particular devices, like Apple OR Android, often limiting their recharge rate. But with PowerIQ™ technology, each port intelligently identifies your device to speak its unique charging language. So plug in any brand or model and enjoy compatibility that doesn’t limit your charging speed.

Uber powerful.

20000mAh of power keep you and your gear going, and going - and going. Add 1000% more battery life to an iPhone, 600% to your large-capacity phone (like a Galaxy S4), or 130-300% to your tablet (depending on its battery capacity) - all away from an outlet. What's more, the added energy efficiency gives you 10% more usable power than the previous generation and many standard alternatives.

Brilliant display.

Interacting with the all-new aluminum-cased beauty couldn't be easier. The LCD simplifies everything - displaying the remaining power (with precision down to the percent), output, input and voltage selection.

For optimal use.

• Please use your device’s original cable or a third-party certified one (such as MFi).
• Compatible with all Apple and Android smartphones, tablets (including the Nexus 7) and other USB-charged devices. The iPod nano, iPod Classic, HP TouchPad, LG G2, Asus tablets and some GPS and Bluetooth devices are not supported.

DC cable for Surface Pro 3

Similar to the post by Galen, I am having trouble finding a Surface Pro 3 DC cable which fits the output DC port on the battery.

Every cable I have found so far appears to have a 2.1mm DC attachment e.g. http://www.amazon.com/gp/product/B00PBGVQQU

This will fit the DC input (charge) port on the battery, but the DC output is obviously much smaller.

I suspect the solution is to find a DC-DC adapter to step down the size.  Can you please confirm what the correct size is for the DC output port? e.g. 1.4mm/1.5mm etc

Charge this battery with different cable

 If I charge the battery with 9V DC cable (instead of 12V), will this damage the battery?

The Perfect Power Companion

I have had this external battery for some time now and have used it extensively. It packs well and works quickly. I mostly use it to re-charge tablets and phones which it does quickly. The battery itself recharges quickly and has an easy to use design. I have not had any problems with it. I did place two cupboard bumpers on either side of the power button so it would not accidently be turned on in a bag or backpack. I highly recommend this external battery!

Recharging cable for this battery pack?

I have this battery pack and I love it! I take it everywhere I go. Somewhere along my travels I seem to have missplaced the charging cable to recharge the battery pack. Any suggestions on the best way to track down another?

 

Thanks!

Cable to connect DC out to Surface Pro 3

Gabriel: thanks for your answer to my previous question.  I bought the Anker 2nd Gen Astro Pro2 20000mAh Quad-Port External Battery

Any idea where one can get a cable that connects to the DC Out port to the Surface Pro 3?  Having a hard time finding one that has the small plug required by the DC out port.  

I found one with a larger connector that fits the DC IN port that said it could be used on the Surface Pro 3...the battery won't charge from that port, will it?  It has the correct connector to the Surface Pro 3 but not for the DC OUT port on the Anker.  Thanks a bunch!
