Frequently Asked Questions
What size inverter generator do I need for my car?
For most car camping and tailgating needs, a generator with 1600 to 2000 continuous watts is sufficient. This can power lights, a small refrigerator, phone chargers, and a TV. If you need to run a window AC or power tools, look for 1800 to 2200 continuous watts. Always consider starting watts for motors.
Can I use an inverter generator to charge my electric car?
Inverter generators can charge an electric car, but it is very slow. A typical 2000-watt generator provides about 1.4 kW, which adds only a few miles of range per hour. For emergency top-ups it works, but for regular charging, a dedicated EVSE or higher power source is recommended.
How quiet are inverter generators for car camping?
Most inverter generators operate between 48 and 58 dBA, which is about the level of a normal conversation. Models like the Honda EU2200i and Yamaha EF2000iSv2 are among the quietest at 48-51 dBA. This is generally acceptable for camping, but check campground noise restrictions.
Can I run an inverter generator inside my car or trunk?
No, never run any generator inside a car, trunk, or enclosed space. Generators produce carbon monoxide, which is odorless and deadly. Always place the generator outdoors at least 20 feet from windows, doors, and vents. Use a carbon monoxide detector for safety.
What is the difference between an inverter generator and a conventional generator?
Inverter generators produce cleaner power with less harmonic distortion, making them safe for sensitive electronics like laptops and phones. They are also more fuel-efficient and quieter than conventional generators. Conventional generators are typically cheaper and more powerful for the price but noisier and less efficient.
