We're working on turning this $2000 van into a do-it-all machine that can tow a car to the track, then serve as a mobile workshop and hotel room for the weekend. Up next: adding electricity.
Electricity is pretty useful–that's why most houses have it, after all–but it's not particularly easy to fin…
Is it a square wave inverter, or a sine wave?
You want a sine wave, some electronics, especially things like battery chargers for tools don't like square wave.

Being able to step out of bed and stroll through the paddock/camping area first thing in the morning on a two-day event with a hot cup of coffee in your hand is one of the most sublime pleasures of motorsport.
I see a "power level" gauge on the inverter. Does that have some way to shut itself down to preserve starting power in the battery just in case?
In reply to a_florida_man :
It's a square wave. Yes, a pure sine wave would be better, but we've used these cheap inverters for years without issue. It charges tool batteries just fine. At the end of the day, it was a great deal, which is why we chose it.
In reply to wae :
Agreed! It doesn't have an automatic shut-down, but we usually have the engine running while we're using it for big stuff, anyway.
I had thought about adding a 2nd battery under the passenger seat with an switch so it would not pull down the vans main battery ,
Does the inverter make any buzzing sounds ?

Nope, the only noise is from the cooling fan, which runs under heavy loads.

Cool. Glad to hear you were aware. Many folks aren’t. Love the van project.
May want to mount that lil guy right-side-up. For extended run time it a warm environment you may run into cooling issues having the heat sink upside down and buried in the floor. I know most car amps are unhappy mounted that way if run for a long time in a hot environment.
I do love a nice cup of coffee in the morning outdoors, definitely one of life's simple pleasures. I make mine on an old Coleman stove, so I can also make some eggs and bacon!
The heat sink is about 1/2" from the floor, and over the past two years it's been fine. I've even run my house off of it through a transfer switch!
Do you have 167 amp. input ? At least that is what you need for 2000 watts. How many watts does the coffee maker draw ? My Mr. Coffee doesn't say.
