The napkin is powered by a thin gel-pack battery, the stand by regular household current.

This electric motor will be powered by a lithium-ion polymer battery that can be recharged using household current.

Most models require resetting the timer if household current has been interrupted.

(Make sure it uses 120-volt household current.)

The batteries can be recharged using an extension cord and regular household current.

Made by Luhr Jensen, the Little Chief brand, which is made of aluminum with a steel interior, weighs about 15 pounds and operates on a regular household current.

The mainstream scientific evidence suggests that low-power, low-frequency, electromagnetic radiation associated with household currents and high transmission power lines does not constitute a short or long term health hazard.

Devices that take the 12 volts of electricity in car cigarette lighter outlets and convert it to full household current can certainly be handy for recharging laptops or digital cameras.

There's something called a carrier wave that can move over wires carrying household current.

As a practical matter, Dr. Brighton said, that required more power than current that alternates evenly, like ordinary household current.
