Getting more out of an inverter

That's about all you can get out of the 12V plugin inverters. Make sure your idling the truck. That might give you a little more power.

Maybe a set of mini jumper cables seems like I remember seeing inverter with some. So you could clip them onto batteries when ever you used it. You cannot do 2,000 watt but maybe 400-500

 

Not from a 12 volt outlet.

We used a 300 watt inverter to run a dell inspiron laptop most of 2000 and 2001. Most of it was made of metal (The inverter) and cooling on the plastic dash became problematic. We stick a armorer's block (A small slab of metal with holes meant to assist in detail stripping a colt) under there with velco and then fastened the inverter to the top. That 300 watter ran off a 12 volt.

The real monster inverter was hard wired to batteries of the truck direct by the freightliner dealer at our expense. That one was able to start anything up to close to 5000 watts, however that engine needed to be running at cruise idle and pushing 15 volts on the alternator to the truck to succeed. In addition the lower bunk had to be up with a fan directed at the inverter for cooling purposes. 4 deep cycle batteries fed it.
