I have a Dell Axim 300 with a problem which I have never seem discussed on the forum.
I have a sync cable from both Moonlight and Gomadic that is supposed to recharge the Axim battery using power from the USB port. Both of these cables seem to work in reverse. They drain power out of the battery. About 10 minutes after connecting, the power may drop from fully charged to low enough to trigger the low battery warning.
I have tried these cables on two different PC's, one a Dell and the other homemade and get the same results with both.
Currently I only use the cable to quickly load a program onto the PDA then disconnect before the battery is completely drained
