Yes, sorry, I meant micro. The worst of all possible ways of charging. Always the first thing to go because it is surface mounted onto a PCB via 5 very small solder areas.
And TBH, although I love zoom products, but when you have a Q2n camera, and a Q2n external power booster, why do you have to connect a usb between the two anyway? You physically bolt them together, would a couple of terminals between the two been too much work?
