Sealey Power Inverters - Pure Sine

Sealey Brand: Sealey

Pure sine wave inverters have been designed to produce the same AV frequency produced on the grid, making them more reliable than traditional inverters, without any fluctuation in power or performance. Operates from a 12V DC power supply found in cars, caravans, boats and HGVs. High performance outlet eliminates electrical interference, reducing noise levels during use. Suitable for powering small TV's, laptops, power tools and various electrical equipment within the wattage rating of the inverter. Features USB port for use on various domestic electrical items such as digital cameras and mobile phones. Aluminium case provides durability and maximum heat dissipation. Safety features include automatic overload shutdown and short circuit protection. Supplied with cigarette lighter plug and/or battery clips/terminals depending on model.
