I recently received a RAVPower 7800mAh Power Bank ( Model RP-PB31 ) for a product review.  In addition to the charger itself, a USB to microUSB cable was included.

Charger and USB to microUSB cable

The charger was pretty small compared to what I have recently tested, but that was expected since my recent tests were higher capacity (over 10000 mAh) units.  This one was small, and actually felt pretty light.  I was able to carry it in my pocket without really noticing it.

Size Comparison
Top : 7800 mAh battery pack
Bottom : 18200 mAh battery pack

The charger is rated to support 2.4A output, so I used my DROK testers and loads to see what it could handle.  Here is what I found:

- 2A load : Unit was able to handle it
- 3A load : Unit maxed out around 2.6A of output
- 4A load : Unit shut off, likely a built-in overload protection

So bottom line, it was able to handle just above the rated 2.4A rated max current.

For real world tests, I just used it from time to time to keep my devices charged and never ran into any problems.

Here are the main points I noticed about this product:

Compact: The battery pack is fairly small and not too heavy, so carrying it in a pocket or purse shouldn't be a problem.

Ease of Use: Like most USB battery packs, the use is very simple.  It has 4 LEDs to show 25% increments of remaining capacity.

Bottom line: If you need a USB battery pack that is good for daily use, enough to keep your devices topped off, then this 7800 mAh unit is a great option.
