Hi,here we have a RING powersourcepro 12 volt to 230 volt 1000 Watt modified sine wave inverter. It was once in a works van some years back to charge the various power tools that where needed on site. It's been lying around gathering dust for a while so I have no idea if it works or not. If you have a modicum of electronics knowledge then maybe you can test it and if needed,fix it. Please feel free to ask any relevant questions and thanks for looking.
