Review on QINLIANF USB Wall Charger with Surge Protector: 5 Outlet Extender + 4 USB Ports - Ideal for Home, Travel, and Office Use (3U1C) by Travis Caminiti

For some people this is a very versatile adapter. Unfortunately I have these square nuts at home and they don't have a center screw in the socket. Also, this adapter only has one set of electrical contacts on the back, so it can only be plugged into one of the outlets. I can't add a center screw and it seems a bit wobbly. I'll live with that, but I probably wouldn't buy it if I knew I didn't have a central screw hole on my outlets and it only has one set of electrical plugs. Another thing is that it is well made. Much luck
