    Default Minimum inverter size required for 2 x 50w electric blankets

    I have a old 150watt inverter and although it doesn’t indicate overload with the 2 blankets connected, the electric blankets doesn’t seem to warm up.. any suggestions?

    I use a dual 120W (2x 60W) electric blanket with my 350W inverter with no issues at all.

    Taking the above scenario and running the inverter all night how much power would be left in a 105amp hour battery. Surly the blankets would flatten the Battery overnight.

    The idea of an electric blanket is to NOT keep it on all night long.

    Switch it on say 30 to 40 minutes before bedtime, and keep it on for another 10 to 20 min after getting into bed. That way you have a lovely warm bed to slide into, and you warm yourself up before dozing off merrily on a cold winter's night.

    That amounts to a total drain on the battery of about 10Ah which is not going to break the bank.

    You could use a warm water bottle to achieve a similar result, but the blanket warms up almost the whole bed.
