How Extreme Is The PowerMonkey Extreme?

Powertraveller sent me a PowerMonkey Extreme -- basically another in their long line of solar-powered big batteries for portable gear -- to test. So I decided to give it a quick drowning. Video after the jump. The specifications sheet for the Extreme states that it's IP67-rated; that should mean it's entirely dust-proof and capable of immersion up to one metre (although it's doubtful that it'd gather much solar energy while it's in the depths). There's really only one way to test those kinds of claims, and while I lack a backyard pool to really test the waterproof nature of the Extreme to the (if you'll pardon it) extremes, it seems to stand up well to a simple beating followed by a jug full of water.
