What size power converter do I need for my RV?
This question from RV owners is the most common question we receive daily. RV Power Converters have come a long way over the years, allowing consumers to buy direct, saving money in the process. RV batteries are a much more expensive replacement so making sure you have a top power converter is important. Converters are much easier to install and most mechanics will charge 3-5 times more for them to install in your RV unit. The power converter is a very important part of a functioning RV that travels regularly.
What is a Power Converter? A power converter changes the 120 volt AC power to 12 volts DC, which is compatible with the low-voltage electrical systems and batteries. The power supplied by the converter can take the place of the power from the batteries and can also recharge them.
The answer to the question “What size power converter do I need for my RV?”
The longer answer would be to add up all the 12V appliances, lights, jacks, slideouts and see what the amperage equals and that will tell what size converter you’d need.
(Our Suggestion) The most popular power converter sold is the Powermax 55Amp PM3-55LK. This converter is the best-priced 55Amp 12V converter on the market and will handle your power needs.
