Most cigarette lighter has a build-in 10A fuse so I don't think any of those can work with lighter plugs

SL Euthtion 2000W Pure Sine Wave Power Inverter 12V DC to 120V AC 60HZ with LCD Display, USB Port, Wireless Remote Control（10M）, Solar, Outdoor https://www.amazon.com/dp/B096KCW...UTF8&
this model above is $208.
or do I stick with renogy at $355 for the model with a remote lcd. Another option is to stick with renogy for $270 and not get the wireless remote...
Any advice?
Don't know what ga my CRV or pickup trucks wiring is, but my 300w inverter has never blown a fuse in those, but my laptop only draws 60w.
And you're right. I never would have tried to run that powerful of a laptop like this.
I don't recall the numbers but there is a chart out there that tells you how many amps / watts can be safely drawn on a particular gauge wire. Keep in mind the length of the wire becomes a consideration too.
Even if your car has a built in inverter for an ac outlet, I don't think it will run that laptop.
There are youtube vids showing how to hook up a dedicated 12v outlet and my next project I will be converting my 20v dc outlet to a 30v dc outlet. Gonna use 10ga wires for that and bigger fuses and a disconnect switch. (only plan on drawing maybe 100w for a newer laptop and charge a solar inverter)
If you do such a thing, install the fuse as close to the battery as possible. And check to see if the alternator can keep up with the amperage draw. Battery size and age will come into play at these watts too.
To get more you have to wire direct to battery with a lower gauge wire.
I have used 300w inverters for years but I'm also not drawing more than 100w at any time.
But, I want to get a solar inverter that I can recharge while driving, so I'm going to step up to a 30a 12v outlet (with proper ga wires!) so the 300w pure sine wave inverter will work as I need it to.
Hobotech on youtube explains this well enough.
Also, discovered while shopping for new inverters that one had to step up to the 500w inverters to get the 4.8v usb ports. All the 300w inverters I was looking at only had 4.2v usb ports, and that's good enough for my needs.
However, that draw should be from the laptops battery, shouldn't it? The inverter would be just charging the battery.
But way more importantly, microwaves want Pure-Sinewave. If you don't give them that, they would make a buzzing sound, and not work as well.

Once you get over a couple hundred watts, the manufacturer includes battery clamps. Obviously this means you cannot use it while driving, but it does increase current capacity quite a bit. Still, in-rush current usually prohibits most all large appliances. ie. Refrigerator, blow dryer, space heater, etc

My CRV battery is on the small side so I never leave the inverter on with the engine off for more than 30 minutes.
The pickup I can run for an hour or 2 without starting issues.
I used to use 150w inverter but the quality and ability to charge things varies so much from brand to brand.
I would get a pure sine wave inverter for the cost these days.
