Surge Protector USB Outlet Extender - POWSAV 8-Outlet Splitter and 4 USB Ports(1USB C Port), Wall Mount Multi Plug Outlet for

Can this unit handle an air conditioner? I don't like to play around with power sockets or electricity Lol.

Do you have to screw it into the outlet? Cant you just plug it in like normal

I was going to buy this but little confused. You have to replace your existing faceplate?

The grounded and protected lights did not come on in the original and replacement units. i've tried the plugs in multiple locations. any ideas? thanks
