So I great discovery had been made tonight. I needed to buy a new FM transmitter for my iPod and I found the TuneFM
. It comes with a car adapter (no more wasted AAAs from accedently leaving my old one on). Much to my surprise the output of this adapter is 5V and has a USB connector (The ones used on most digital cameras) I plugged it all in and to my joy the transmitter works & the charge icon comes on in the iPod.
While I don't know how much power is actually getting to the iPod for charging I think it may still charge. I am currently running my iPod battery down to check how well it works.
Anyone else using this setup that can comment on its charging capabilities?
