The EW-420USB Power Inverter converts low voltage, direct current (DC) to 120-volt alternative current (AC) when connected to the 12 V outlet in your car, truck, RV, or directly from a dedicated 12 V battery.
The EWRC2 can be used with the EW-1100, EW-2000, EW-3000 and EW-4000
inverters. It features a LED indicator showing inverter status, an on/off switch
and a 20’ cable that simply plugs into the inverter.
