Yes, power bank, they usually are rated 5V and 0.5 up to 2 Ah, maybe more the fast charge ones, can't say for that. I would be careful with the cable, measure it first, which is+ and which -, don't know how R10 would manage reverse polarity and I can't remember that. About the reset function I have read only, and I do not remember how long to keep it pressed, sorry.
