Charging your iPad 2

It was brought to my attention that the iPad does not charge very well when it is plugged into a computer's USB port.  This problem is worse on most PCs and in many instances the iPad will not charge using a PC, but will on a Mac.  However, the rate at which it will charge is much lower using any computer over the wall outlet.  This is because most USB ports only support about 1/2 amp for charging, where the wall allows for up to 2 amps.  

So my recommendation is to charge your iPad overnight using the wall adapter once the charge is below 30%.  This way by morning your iPad will be charged to 100% for the next day.  Remember the battery can last 10 hours of regular use or up to 3 days with sporadic use.
