These high efficiency power inverters produce a pure sine wave to power 230V mains equipment from a 12V battery or DC power supply. Perfect for use while camping, in commercial vans/lorries, or as a means to convert charged batteries for back-up power in case of a blackout. Ideal for use with TVs, computers, kettles and other everyday appliancesOver 90% efficiencySoft start minimises inverter shutdown when using large inductive loadsHigh accuracy output wave form with less than 4% THDReverse polarity protectionLow/over voltage input protectionShort circuit, overload and overheat protectionBuilt in 1000mA USB socket on the 600W & 1000W versionsLED and audible fault indicatorSupplied with 1 pair of 800mm DC power cables and a spare blade fuse12V input versions available, please ensure the correct version is selected for the input power to be usedPlease note: Ensure the device is well within the inverter output power rating. We recommend using an inverter capable of supplying a minimum of 3 times the device’s rated power to avoid damage to the inverter by any current surge (especially for fridges and freezers which can surge up to 7 times the rated power)
