..afternoon, just looking for a bit of clarity. Got a few long days coming up and want to make sure we get everything recorded. We'll be using a Fenix 5S, 500 and a 705 (I think). I think that I can charge and record on the go to the 500 with a power bank and OTG USB lead? Would the 705 need the same type of connection or is the standard USB ok. I have no idea about the Fenix 5S, I realise I'd have to take it off to charge but can I just connect a power bank to it's data / charging lead and have it continue to record? Any suggestions gratefully received.
