Frequently Asked Questions

What is a power inverter used for?

An inverter converts DC electricity in batteries or fuel cells into AC electricity. Power inverters are used to charge smaller electronic devices such as phones and cell phones, but higher powered ones can be used for more. An inverter is the opposite of a converter, which converts AC power to DC.

Can I keep my inverter on all the time?

You can, but you don’t want to. An inverter will drain your car battery if not turned off. It is estimated that an inverter needs to pull 10 times more power off the battery than it actually supplies.

How big of a power inverter is recommended for a car?

It is suggested that inverters that are 2500W or less should be used on your car.

Does an inverter take power when not in use?

If the inverter is on, then yes, it will still draw power. In order to ensure it doesn’t drain your battery, you need to turn the unit off.
