Frequently Asked Questions (FAQs)

1. Are power inverters safe for car's?

Today's power inverters are built-in overheating protection and can protect your devices but if you use it this way for a long time, it will be harmful. So, don't use it directly under the sun or near the heater outlet. You should choose a power inverter with a suitable input voltage.

2. Will an inverter damage my alternator?

A 3000 watt inverter can only deliver 1,200 Watts @ 120 VAC using your vehicles existing DC charging system. (see formula above). Attempting to acheive 3,000 watts output from an inverter without the installing multiple batteries and a 250 AMP alternator will result in damage to your vehicles charging system.

3. Do car inverters drain 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.

4. Can you connect an inverter directly to a car battery?

For powering loads of over 150 watts, you should connect the inverter directly to your car battery. This requires a 4-gauge power cable and draws power directly from the positive battery terminal. An in-line fuse or circuit breaker (typically 80 amp) installed near the battery is a must.
