Not to get into too much detail - this says it's suitable for laptops and appliances such as fridges but I'd caution against it. Spend a little more and get a pure sine wave inverter. The longevity of your electronics and the efficiency/energy savings will pay for those few extra dollars

Yes pure sine wave inverters are better, but a modified sine wave will do in a pinch. Just don't use it often. Also I don't know about pulling 400w through the cigarette lighter. Best case scenario is you have a 20 amp fuse, and I know it says "12v" but really a topped up battery is 12.6. If your car is running the alternator is hopefully putting out at least 14v. So 14v*20amps is 280w. The 400w converter will work up until it blows the fuse so just keep it under what your car can handle. I would keep power draw around 200w if I had a 20a fuse.

Here's a fairly well reviewed pure sine inverter that runs off the cigarette lighter. It's only 300w, but that's all I would need.

Also worth noting it won't do 400w. Most cig lighter ports have a 20a fuse (and wiring isn't designed to handle more than that). Car batteries are 12v but really run between 14&15v. 20x15 = 300w.

Most laptops would charge through an AC-to-DC brick anyway. A lot of portable appliances would have those bricks, too.

Finally got around to testing the inverter and it turned out to be pure crap.

First, I tried to charge a power station that accepts about 120W through its brick. The voltage shown on the little display dipped to about 11V (from 13.2V of the source battery). The source battery can deliver 2000W easily so it did not have any issues. The power brick/charger connected to the inverter made a bad ticking noise.

Then I tried a 300W tool. It started, I could see the voltage go down to 4.2V and shut off. Ran about a second.

Then the inverter was dead.

It's plastic garbage. You get what you pay for...
