drive power supply Can power multiple devices at the same time. The output is stable safe and reliable. Pure sine wave intelligent filtering does not interfere with electrical appliances and protects them. High conversion efficiency (up to 92%) and low power consumption can greatly extend battery life. A pure sine wave output can operate even the most sensitive electronic equipment better than a modified sine wave. Multiple ports make your road trip easier. The voltage converter generates 220V alternating current (AC) from the 12V/24V direct current (DC) connected to the battery as a grid backup without interference just like in household appliances. The conversion efficiency is 92%. It is very suitable for inductive load equipment with more stable output current. Smart LCD display input
