I just got my first Leica camera, a C-Lux. It's also my first camera which has a battery that can be charged via USB. I've tweeted Leica-USA and emailed them but haven't gotten a reply to this question yet.
Can I use a portable phone battery/portable charger/power bank type thing to charge my battery? The specs state that it needs to be plugged into a computer or the Leica charger, ONLY. But since the USB cable is standard USB-A, I would think it's fine to use the above, like you would use to charge a cell phone on the go.
