Power devices that require less than 120 volts AC. They can also be used to charge backup batteries.

Couple these adapters with a cord that matches your outlet and length requirements to run DC-powered electronics. Instead of plugging directly into an outlet, the body of these adapters sits on the floor or other surface, so it remains out of the way and won’t block multiple outlets. These adapters use switching regulation—they produce the stated voltage even when your outlet’s power or the power drawn by your device fluctuates. Most have an LPS low-voltage output, so if something fails inside these adapters, they’ll limit the risk of electrical shocks. They meet U.S., Canadian, and European safety standards. Many also meet U.S. and European standards for energy efficiency.

When choosing an adapter, match the output voltage and polarity of your device. Look for the polarity illustration on your device or the adapter you're replacing. The current you choose should, at a minimum, match your device. You can choose a higher current, but it will not improve performance.

Plug these adapter cords into a standard outlet and they change AC voltage to DC voltage. These cords use switching regulation, so they produce the stated voltage even when your outlet’s power or the power drawn by your device fluctuates. It also means they won’t get too hot. They have an LPS low-voltage output and Class II shock protection, so if something fails inside these cords, they’ll limit the risk of electrical shocks. These cords meet U.S. and Canadian safety standards as well as U.S. DOE (Department of Energy) Level VI standards for energy efficiency.
