110v Mails Stepdown
Hello,
Long time reader, first time poster Just wondering if you guys could offer me some advice - I've just got a Yokomo YZ183 charger which can run off either 12v or 110v (US/Japan mains voltage). Now my 12v supply is one of those little black 10amp things, not man enough to power my Duratrax ICE and the Yokomo at more than 3.5amps each. So, rather than buying another 12v supply, I was thinking of getting a stepdown convertor. Maplin sell one for £15, the specs are Input 230v, Output 110v/120vac 100w. I'm not sure how to figure out if that will be enough to run the charger - anyone know? Thanks Matthew (argh, can someone change the title to mains, not mails!) |

Thanks for the offer. For £30 I might as well get another 12v supply though!
How would I calculate the wattage I'll be drawing charging at 12v, 6 amps? |

If my fading GCSE memory is correct, I reckon the most I can draw below 100w will be about 8 amps, so I'd probably want something beefier.

Power = Volts * Amps, so indeed, @12V that will only give you 100/12 = 8.3A
Personally I'd spend £30 on a 13.8V 20A Propeak one and be done with it.
