Frequently Asked Questions
What can I run with a Cobra POWER 500W inverter?
You can power small electronics like laptop chargers (up to 90W), TVs up to 32 inches, CPAP machines, small coffee makers, and charge multiple devices simultaneously. Check wattage ratings—continuous load should not exceed 500W.
Why is my Cobra 500W inverter only putting out 180 watts from the cigarette lighter?
The cigarette lighter socket may be limited to 10-15A (120-180W). For full 500W output, connect the inverter directly to the battery using included cables. This is a common limitation of car sockets.
Will a Cobra 500W power inverter run a mini fridge?
It depends on the mini fridge's wattage. Many mini fridges draw 50-100W, so it will run, but startup surge may be higher. If the fridge's running watts are under 500W, it should work. Check the label.
Why does my Cobra POWER 500W show open ground on an outlet tester?
This is normal for inverters without a true earth ground. The inverter creates a floating ground; testers may indicate open ground. Use a GFCI outlet for added safety, and it's designed for use in vehicles, not as a home ground.

Fantastic inverter for the price
I use this in my truck for camping trips. It runs my cooler and charges my devices at the same time. The USB-C fast charging is a bonus. Great value.

Good for basic needs
It's compact and works well for charging laptops and small appliances. The fan is a bit noisy, but that's expected. The price is right, especially at 50% off.

Solid performer
I've used it in my work van for months. It powers my power tools charger and a small TV without issues. The GFCI outlets are a nice safety feature. Highly recommend.

Okay but not for heavy use
Works fine for light stuff like phone charging, but when I plugged in a mini-fridge, it struggled and the fan got loud. I didn't expect it to run a fridge, but I thought it could handle more. It's fine for basic use.

Overheat warning after 10 minutes
Used it to run a small TV and it kept overheating. The warning light came on and it shut off. Maybe I got a dud, but I'm disappointed. Returning it for a refund.
