Pure Sine Wave Combined Power Inverter Charger 12V
This top of the range power inverter is one of the best inverters on the market. It is very reliable due to the electronics in the inverter only changing the wave form to sine wave AC power with the in-built transformer stepping the voltage up from 12V to 240V, where other less reliable inverters use transistors and heat sinks to convert both the sine wave and the voltage.
