When you need reliable mains-quality power on the move, a modified sine wave inverter often falls short causing interference, equipment noise and unreliable performance. The Sealey PSI300 Pure Sine Wave Power Inverter delivers a clean 230V 50Hz output that mirrors the AC frequency produced on the grid, making it a dependable solution for use in cars, caravans, boats and commercial vehicles. With a continuous output of 300W, the PSI300 is well suited to powering small TVs, laptops, power tools and other electrical equipment within the wattage rating. Its high-performance outlet eliminates electrical interference, keeping noise levels low during use. A USB outlet (5V DC 1A) allows you to charge or run small devices at the same time. Housed in an aluminium case for durability and maximum heat dissipation, the PSI300 also includes automatic overload shutdown and short circuit protection. It is supplied with a vehicle accessory socket plug and battery clips for flexible connection options. Dimensions: 200 x 110 x 60mm.
