Bestek 500W power inverter

The Bestek 500W inverter is a power inverter (or voltage converter) designed to turn the 12V direct current of a car, motorhome or boat battery into 220-240V alternating current, identical to a household mains socket. It is aimed at those who want to power small electrical devices at 220V off-grid: in the car, in a van, camping or on a worksite.

With 500W of continuous power and a higher peak reserve for start-up spikes, it covers common portable needs: laptop charger and power supply, small appliances, lighting, light tools, consoles or small audio devices. It usually combines one or more mains sockets and USB ports, letting you power a 220V device while charging phones and tablets at the same time.

On safety, it includes a cooling fan that kicks in under load, as well as electronic protections against overload, over-temperature, short circuit and abnormal voltages. It connects either to the cigarette lighter (for moderate power) or directly to the battery via clamps to use the full available power.

Keep in mind the limits of this type of device: 500W suits small devices, but not large appliances (oven, hob, powerful heater) or very power-hungry motors. The cigarette-lighter socket is also current-limited: to draw the full 500W, a direct battery connection is recommended. Finally, with the engine off, take care not to drain the vehicle battery.

Simple, compact and versatile, the Bestek 500W inverter is a handy accessory to keep a 220V socket within reach wherever you go.
