Hi,

 

Does anyone know what is needed to convert 240v to a 12v car plug? Thing is is needs to be 10amps for a small hoover so the ones on Ebay all seam to be max 1 amp.

 

Cheers

you mean like this?

Yep something like that but can deliver 10amps

Are you sure you 10amps for a hoover? is it jet powered lol

 

Most car invertors ie 12v to 240 will only deliver 1000watts approx 4amps

 

What exactly are you trying to do ( yes i have read your description) lol

yeah the paperwork for the hoover says power consumption 120 watts, max current draw 10 amps.

 

After a small hoover that I can clean the stove with that will fit in a unit in the alcove. If the PSU will be expensive I might as well buy a new small hoover. It's just that I have a powerfull small hoover sitting in the garage that would be ideal for the fact it's 12v.

 

Been told that I could use a PSU from an old PC

must be a misprint in the amps lol, you can run 3.1kw off a 13 amp plug, so a 1000watt is 5 amps, work it down from there, you should be fine with the one above.0.5amps

I though it worked out watts/volts = amps so it does work out to 10amps. Anyway, think it's easier to just buy a new small vacuum ;)

yeah power in watts divided by volts does equal amps.

 

or P=I2R or P= V2/R lol

240v x 120w = 0.5amps

12v x 120w = 10amps

 

You can buy a regulated DC power supply from Maplins, i got one that i use for bench testing leds etc, gives out 13.8v but only 2 amps continuous and 5 amp surge for £14, the larger spec ones are more expensive, but they will have one that will work, but outway the cost to a new small hoover lol
