Yes, a big-arsed power brick is probably on the agenda. My current big-arsed brick, home built, can charge it but apparently does not have sufficient oomph to do so while the headset is powered on and playing.
I may also obtain an unwisely long cable and dangle it from the ceiling for living room use. My previous headset is wired, so no great loss there. In fact and come to think of it, I already have a 10-ish meter USB-C extension which can power my Reverb G2; that'll probably work.
