I might've found a AA USB battery charger device. http://www.ebay.ca/itm/270810499131
Just for grins, and if no one else feels like it, I'll buy the device. I won't need it much, as I mostly travel by vehicle and with my laptop, but I don't mind having an extra device around to charge things on an emergency basis if my laptop isn't available or convenient. And I *always* have AA batteries around.
I used the search terms "2A usb charger -car" without the quotes on ebay.d
PeterT/Jeff - I'm a bit confused though. A few postings back in this thread Jeff stated that "I've used several and they've done the job." So we don't really need to pull the charger apart. Assuming that Jeff meant that he used several with the Vox.
