Testing a 12 volt to 220 volt – 500 watt, power inverter from CDR King. It’s connected to a Motolite Solar Master 100 Ah battery which is charged by my solar panels.
The inverter was putting out around 238 volts and my laptop was drawing around 35 watts.The inverter cost 950PHP (24 USD).
CDR-King also stock inverters which include a usb port on the back but I already have a 12V to 5V 2 amp usb adapter wired up which I think is likely more efficient than running a big inverter just for USB power.
