I've been looking at power converters that plug into the 12 volt plug in your vehicle or tractors. I have found some cheap ones on amazon that are for laptops and such, I'm sure not what I'm needing. I would like to be able to run a large drill for drilling holes in hedge post, also would like to be able to run my clippers for freeze branding. Maybe a small air compressor when dealing with flat tires. I get tired of lugging around the generator times when I only need to hang one gate. Does anyone make one large enough to run that drill? Any suggestions? Thank you much
