Safety, Efficiency, and Power Inverters

A power inverter changes direct current (DC) to alternating current (AC), but does not produce the power, itself. These inverters provide portable, efficient power, are convenient to use, and versatile of purpose. Power inverters from CyberPower convert automobile DC power to AC power to rapidly charge and power laptop computers, tablets (including iPads), MP3 players, and other USB mobile devices. They also supply surge protection to safeguard electronic equipment.

Our power inverters offer many features for safety and efficiency, including automatic shutdown, built-in surge protection, and soft start technology. For more information about these and other features, see the user manual or Web page for the specific power inverter that you want to use.

NOTE: Features vary by model.

Automatic-Shutdown ensures that the power inverter automatically turns off to prevent your battery from draining.

Built-in Surge Protection safeguards electronics against power fluctuations, such as those which occur during vehicle startup and shutdown.

Sensitive Electronics Safety Features provide surge protection and automatic shutdown to guard electronics against power fluctuations, temperature extremes, short circuits, and high or low battery conditions.

Soft Start Technology protects electronics against power fluctuations.
