You can charge the Blackvue Power Magic Ultra Battery B-124 indoors using a main to cigarette 12-volt dc adapter. Does anyone know if you can do the same with the B -124 X version? The BlackVue helpline UK says it cannot be done, but if f you have a mains plug to cigarette lighter plug adaptor cable that regulates the voltage and amps I can’t see why it wouldn’t work. And if so what adapter would you recommend?
