My Uniden SDS-100 is charging from the supplied wall adaptor via the USB cable. About 3-hours and still charging now, too long, and it might run for almost 4 hours when ready. So, Is it possible to find online a pocket power brick used for charging cell phones as an alternative way to power the SDS scanner. This brick worked fine on my Whistler TRX-1, just asking if it has been tried.
