Q: How can I get DC5V to power the alarm from a 220V AC plug ?

Asked by arp22 on 2018-01-09 16:31:23

Kenny It uses the same current as a USB port (5V 1 amp). It comes with the cable, but not an AC adapter. So any power adapter that converts 220 to a USB jack will work for you. There are several 110 AC to USB port adapters. One of those and a 220 to 110 adapter would work as well.
