RV52.com has created an RV Power Converter Size Calculator. I just didn’t see many of these around the interwebs so I thought, “what the heck?”… I’ll just make one.

I had to make quite a few approximations, but after some fun programming, I have something that can let you get a pretty good idea about your converter size.

I also put in an additional easter egg where I give you an extra indication of how long your item – when in an average usage mode – will run on the battery. I make an assumption on the battery size since batteries vary quite widely.

Here is the RV power converter and battery usage calculator.

There are several other nice power converter articles and comparisons that can help you with hunting down the converter you need.
