I want to invert some power from my wheelchair. It has 2 12v batteries. It already converts 110v to charge them.
Here's what I want to do... 1) Power my video camera/charge the camera battery. 2) Run my electric lawn mower. (IMG:style_emoticons/default/wink.gif) 3) anything that needs 110v... (IMG:style_emoticons/default/idea.gif) Anyone know what I need ? I dont know where to begin... |

Check the power ratings on some of the devices you intend to use. The lawnmower almost certain draws more than the 5 amps or so you'll get out of a 700W inverter. So will a vacuum cleaner. Simply multiply the amperage rating on the device by 110v to get the number of watts drawn. I'd expect a 700W inverter will have a 7-8 amp fuse on the output. The batteries on your chair are very likely capable of delivering 1000W or thereabouts, at least for short periods. 750W is about 1HP, btw. That should give you some idea of how much power is being dealt with.
