What is the current rating(Amps) or power rating(Watts) of the winch?

the only info it came with is the same as the stuff on the ebay page...

'Motor: Performance magnet, 0.7kW / 0.9hp(12V)'

and it looks like the current is variable with a max of 90amps
any help?

Cheers,

Will

0.7kW = 700 Watts. At 12v that would be 58 1/3 Amps. This means you would need a power supply that could produce at least 60 Amps. You could do that with an old TV Transformer (scrapped from a very old B/W TV), some large (700W) rectifiers and 12v electrolytic capacitors for filtering. This supply would pull 3 Amps from the 220v source, so I'd put a 4 Amp fuse on the primary.
