Our take on the Tessan Multi Plug Wall Outlet Extender 4 USB Ports

The Tessan Multi Plug Wall Outlet Extender plugs straight into a wall outlet and turns one socket into four AC outlets plus four USB ports, with surge protection built in. It mounts over the existing outlet instead of sitting on a cord, so it stays put and keeps the floor clear. It suits desks, kitchens, nightstands and travel where outlets are scarce. Against corded power strips it trades reach for tidiness and a smaller footprint; it carries less surge capacity than full-size protectors, so sensitive gear is better served by a dedicated unit.

Questions and answers

Does it need a cord or battery?
No. It plugs directly into a wall outlet and draws power from it.
Can I use all four USB ports at once?
Yes, but the ports share a total output, so charging slows when several devices are connected together.
Will it fit a standard US outlet?
It is designed for standard US wall outlets and mounts over the existing cover plate.
Does it protect against power surges?
It has built-in surge protection, though with less capacity than a full-size surge protector.
Can I still use the other wall socket?
The unit covers the second socket of a duplex outlet, so that socket is not usable while it is installed.
Where is the Tessan Multi Plug Wall Outlet Extender 4 USB Ports cheapest?
At Best Buy, for $20.12, as of our latest check.
