Thanks guys - I'm now a better informed beginner!

Many thanks Geoff - I will take your advice. I'm still confused about the difference between the reading on my power meter which says 161watts and what Ohms Law says it should be based on the Amps X Volts. Not to worry, an 800watt inverter seems to fit the bill if connected to a fused supply...

Thanks for your thoughts Guys - I think you are misunderstanding my question. The background is that I have a mobility scooter, the onboard batteries being charged by a 240v charger when I am at home. My problem doesn't not relate to the charging of the batteries when I can attach the charger...

Many thanks - pure sine wave certainly also double the wattage - good advice. My quandary is that following Ohms Law V x A =W  the wattage of my battery charger should be 268.8 but the shown value according to my power meter show 161w. Clearly if this is multiplied by the Power Factor of 0.6 =...

My battery charger shows readings as follows on my power meter. 240v  MAX Watts  161 MAX Amps  1.12 Power Factor 0.6 I want specify a 12v to 240v Inverter - what capacity should I specify - based on the wattage or the ampage?
