I'm also wondering about iPad charging. Firebox says "It is best not to charge iPads or iPad2s through USB, it doesn't charge them to the full extent. " but this doesn't make sense as Apple themself bundle the iPad with a USB charging adapter which you plug in the power outlet.
So, will this charge an iPad ?

Firebox says: Agreed Max, that was a bit misleading. This will definitely charge an iPad when plugged into the mains. The point my colleague was making is that there are reported issues of iPad (1&2) not charging fully from some USB sources (laptops, PC's, keyboard ports, etc). Use the supplied 10W charger and cable for best results.
