How to Install an Inverter in a Car

If you’re looking to get 120-volt power out of your car or truck, installing an inverter is the way to go. An inverter is a transformer that changes the voltage from 12 volts, the power of a car battery, to the 120 volts needed to run power tools or laptop computers.

When shopping for a power inverter, make sure to invest in a good quality unit like the 1000 watt power inverter mentioned in this post. This particular unit comes equipped with two cooling fans, which are necessary to prevent overheating. It also has 220-volt receptacles and two USB ports, making it perfect for charging your phone in a pinch.

It’s important to consider your power usage needs when selecting an inverter. If you need more power, consider investing in a 1,500 watt inverter. However, be sure to avoid buying a cheap unit and trying to overuse it as it may melt.

When installing your inverter, you have two options – portable or permanent installation. For a portable installation, simply connect the clamps to your car’s battery and use it whenever you need it. If you’re doing serious long-term work, like using an electric chainsaw, start the car and let the alternator generate the 12 volts needed to charge up the battery, which in turn sends 12 volts to the power inverter.

For a permanent installation, wire the inverter directly to your car’s battery terminals using thick gauge wiring to handle the power output. The inverter can then be mounted wherever you like.

Overall, a power inverter is an excellent investment for anyone who needs access to 120-volt power while on the go. Just remember to avoid buying a cheap unit, consider your power usage needs, and choose between portable or permanent installation.


Can you install an inverter in a car?
Don't worry: You can plug a small power inverter into your cigarette lighter, or even your car's accessory socket. If you want to get a larger inverter, however, you'll need to wire it directly.
Can I wire a inverter directly to car battery?
The small units also come with cables that can be clamped directly to a battery. If you want an inverter that will plug into your cigarette lighter, you must choose one that is 450 watts or less. Larger inverters (500 watts and over) must be hard-wired directly to a battery.
Can you install an inverter yourself?
Many inverter systems come complete in a handy mobile box with the batteries already connected, however, this does not mean you cannot install an inverter or connect batteries yourself.
Do inverters drain car battery?
Inverters can also drain your battery quickly unless your engine is running and charging your battery. Most inverters have an audible alarm when they sense a lowered power source, but it may be to your advantage to buy a bit more expensive unit that shuts itself off when it senses a low battery.
