5 out of 5 eggs Good Capacity, Decent Output 08/08/2013

This review is from: PowerWalker 7200mAh Rechargeable Portable Battery w/ Dual Output, LED Indicators - Black


1) 7,200 mAh @ 3.7v. Converted to 5v is approximately 4000 mAh @ 5v.
2) 1 A output for one port and 2 A output for other port (if used exclusively).
3) LED indicator of remaining capacity


Requires a micro USB connector for charging?

It's pretty common now, but it would have been nice to have been a mini USB instead.

Other Thoughts:

Keep in mind that you will need a USB charger capable of outputting at least 700 mAh I'd recommend a USB charger with at least 2 A output to ensure a quicker charging of the battery pack. Otherwise, it'll take ~5 hours to charge the battery pack from 5% to 100% using a 1 A output charger.

As you're probably aware by now, when both ports are in use together, each port only puts out 1 A each.
