With this inverter / converter, you can use your 230 V devices with a 12 V battery and a continuous output of 300 W with short-term peak performance of up to 600 W. The nominal power for connecting the cigarette lighter is maximum 150W. 1 EU mains power socket – ideal for the power supply of laptop, TV, fan, DVD, GPS, lighting, musical instruments, solar panel or other electronic devices. 1 USB connection – charges, thanks to AC inverter, e.g. mobile phones, tablets, and other mobile devices. Includes plug for the car cigarette lighter and direct connection to the car battery. Additional practical functions: LED indicator, power switch and high speed fan. Pure sine wave – a pure sine voltage converter with pure power signals, capable of generating exactly the same current that you can use with power outlets at home. It is therefore safe to assume that if a device works for you at home, then it will also work with the pure sine voltage converter.
