From what I understand, the N800 will not charge from a USB connection, but it will draw enough power so that it will no longer drain the battery.

Being that the USB and power adapter are so close together, has anyone tried bridging the two so that connecting the N800 to a PC would actually charge it?

From what I recall a USB port should provide a max of 5V@ 200ma, and being able to charge via USB would mean one less power adapter to carry.
