Battery Life
In terms of battery life, the PowerClip 5200 provides average and respectable battery life, delivering only 342 minutes of power during our intensive, ‘real world’ tests.  Discharge rates are significantly less than industry averages, however.  In tests, the PowerClip 5200 charged devices at only 30% the speed of competing portable chargers.

Power/Size
Due to it’s relatively small size and light weight, the PowerClip 5200 offers good power per cubic inch, and was actually second overall among all mid-size devices for power per ounce.

Durability
The PowerClip looks as though it would be a very durable device.  Tests, however, yielded surprisingly different results.  Lightweight compression tests easily separated the seams between the top and bottom half of the device, and because the plastic case cracked easily under lower-stress drop and impact tests.

Features
Unlike many competitors in the mid-size category, the PowerClip 5200 only provides a 1 amp USB charging port.  It does, however, include power level indicators, a connector loop, carabiner, and integrated LED lights. 

Value
In terms of battery life and power per dollar spent, the PowerClip 5200 actually scores a respectable third place among all mid-size devices tested.
