I have a 200w pure sine wave inverter that I use for inductive chargers such as the electric toothbrush. I am thinking that it might be quite nice to also use it to power the electric blanket when off hook-up. Blanket is rated at 85w and would be used for preheating only, maybe 15 mins.
Now I wouldn't have thought that would be a problem. I know the controllers of modern electric blankets can have problems with modified sine wave inverters, but as mine is pure sine wave that's not an issue.
However researching the issue I came across this:
I would like to run an electric blanket and a small tv in my caravan, total watts about 400. What size inverter would you suggest and suit my needs?
Appliances that have coils that produce heat typically require 3 to 7 times the listed power. Therefore, if the blanket is rated at 100Watts continuous, you may require a 1200W Inverter just for the blanket.

This doesn't seem right. Ok, so there are wires running up and down the electric blanket but surely that's not the same as a coil? So are they right - or just trying to sell a much larger inverter than necessary?
