How many watts are in a car battery?

My uncle says that you can use your car battery to run your refrigerator during a power outage. How many watts are in a car battery?

Shannon Martin · Updated on
Reviewed by Shannon Martin, Licensed Insurance Agent.
Your uncle sounds like a creative guy! For clarification, a refrigerator runs on watts, and a car battery runs on volts. We will need to use a little math to help answer this question.
Watts equals amps times volts. The average car battery is 12.6 volts with 105 amps. This would equate to 1,323 watt hours. So, your uncle is right!
You will need to shop for a car inverter. Find one that is at least 1,500 watts, and it will help you power your refrigerator for up to five hours—usually without damaging your car battery. Considering how much food we keep in our refrigerators, a $200 car inverter is a bargain!
If you live in an area that has frequent power outages, make sure you have the proper homeowners or renters policies in place. This is where

How do I fix Bluetooth static in my car?
One of the reasons I got the car I have now was the stereo system—it’s really good, and I’ve always used Bluetooth to play music from my phone. Lately, though, there’s always static behind the music playing, which gets annoying. How can you fix Bluetooth static in a car?
