Haha - right!
The hub actually has only a 1000ma wart on it, but I've only got one other device attached, which is *probably* not high-power. But, the cube isn't warm either; I don't think the hub is really supplying power.
The power supply reads 5.35 V at rest, and then 3.7 V after you plug it into an active strip (on the USB ports themselves), with no devices plugged in. So, the power cube probably isn't even regulated in addition to being too small.
