Technical FAQs 4

What is a pure sine inverter?

The primary job of an inverter is to take DC power and modulate it to imitate the AC power of your home. Most inverters are “modified sine,” meaning their alternating power is “choppy” instead of smooth. Pure sine inverters use additional (and expensive) circuitry to better replicate what you get from the wall plug at home.

How to choose a car power inverter?

Battery Size and Health – If your vehicle’s battery is old or small, it might struggle to support larger car power inverters—especially when the engine isn’t running. Inverter Type – Decide between pure sine wave and modified sine wave depending on what you’re powering.

Do you need a sine wave car inverter?

Devices like washing machines, large refrigerators, or appliances with digital displays and compressors may behave erratically or shut off completely on a modified sine wave inverter. That’s why experts often recommend pure sine wave car inverters for such applications. In general, if you’re unsure about plugging something in, read the label.

Should you use a car inverter alone?

If you’re depending on them for health and safety, don’t rely on a car inverter alone—unless it’s a pure sine wave model with a robust battery backup. Devices like washing machines, large refrigerators, or appliances with digital displays and compressors may behave erratically or shut off completely on a modified sine wave inverter.
