Can I leave my T/C plugged in to A/C when not in use?

Pretty simple fix for CO detector is an illuminated rocket switch mounted right next to it so you can turn it off for storage, no battery drain. Any backup cameras that bluetooth to nav unit should be switched as well, the transmitter keeps trying to send to screen even when everything turned off and drains batteries in 3 days or less, that is I'd you have it wired to constant hot for on demand viewing of what's behind you.
