My Buying Guides on 45 Amp Power Converter For Rv

What is a 45 Amp Power Converter?

A 45 amp power converter is a device that converts 12 volt DC power from your RV’s battery to 110 volt AC power, which you can use to power your appliances, lights, and other devices.

Why do you need a 45 Amp Power Converter?

If you have a large RV with a lot of electrical appliances, you’ll need a 45 amp power converter to provide enough power to run them all at once. A 45 amp power converter can also be useful if you plan on using your RV to boondock (i.e., dry camping without hookups).

What are the different types of 45 Amp Power Converters?

There are two main types of 45 amp power converters:

  • Non-inverting power converters convert DC power to AC power without changing the frequency. This type of power converter is less expensive than inverting power converters, but it can’t be used to power some sensitive electronic devices, such as laptops and TVs.
  • Inverting power converters convert DC power to AC power by first converting it to a higher frequency, then back down to 110 volts AC. This type of power converter is more expensive than non-inverting power converters, but it can be used to power any type of electronic device.

How to choose the right 45 Amp Power Converter for your RV

When choosing a 45 amp power converter for your RV, you’ll need to consider the following factors:

  • The number of amps you need. The number of amps you need will depend on the number of electrical appliances you plan on running at the same time. A good rule of thumb is to choose a power converter that is rated for at least 10% more amps than you need.
  • The type of power converter. If you have any sensitive electronic devices, you’ll need to choose an inverting power converter. Otherwise, a non-inverting power converter will be fine.
  • The size and weight of the power converter. The size and weight of the power converter will be important if you plan on lugging it around with you when you’re boondocking.
