Converting 12V to 110 without a power inverter


Unregistered guest
I am really broke, but I want to hook my laptop into my truck. I have all of the proper audio/video connections, but the battery runs dead within an hour. I want to know if there is a way to make a power inverter. I don't have the sixty bucks to go buy a good one.

I may have completely missed something, but doesnt that laptop have a transformer anyway to convert the 110v back to 12. Couldnt you just skip the transformer and run the laptop off the 12v supply from the car.

Walmart has inverters for under $25 for the use of laptops. And laptop OUTPUT is in volts with my Dell being 19.5v DC and the input being 100-240v AC

On eBay those converters start at $1. Most sell for $10. For notebook, all you need is 35w - 50w.
