Here is a space heater that plugs directly into a wall outlet, so you can use it in any room without a cord. This Wall-Plug Heater lets you adjust the temperature from 60F to 90F. It has auto shutoff timer and 2 AC outlets on the side, so you can still plug in your other devices while the heater is running.
The heater can heat up rooms up to 120 sq. ft. The fan speed is adjustable.
