Abstract
An electrical unit outlet device is disclosed for controlling power isolation, based on a pre-determined time, for a device charger, while remaining plugged into a power outlet. A power isolating circuit cuts any power to the charging device off when charge is complete. Multiple embodiments are disclosed including a ground fault interrupted electrical unit outlet that may be controlled by a timer to shut down after batteries have been charged is disclosed and claimed herein. All circuits will subject to ground fault interruption protection and may be subject to surge protection as well. In another embodiment, a lamp with timed charging outlets that shut down when batteries are being charged is disclosed and claimed herein.
