There's also a Wagan Slimline 1500W DC to AC Inverter but it doesn't come with the cigarette lighter accessory or battery clamps. It seems like it would be a more permanent installation. That is $50.24.

If they were to design it with more power than wires would have to be thicker gauge and well as contacts rated for as much as well. It should be fine if connected directly to battery but there you also get limitations due to battery capacity, car alternator power and few other issues that can arise. Unless car has big battery (or two) and high power alternator the inverter might suck more power (depends on demand of what's connected to inverter as well) than car can handle and it might not be best situation for car electronics and computers as well. That's why 1.5-2KW ones are risky IMO.
At that point small quiet dual fuel generator with propane might be better option.

And actually using a deep cycle battery is the best use for this. Why? The battery itself is built for constant deep draw then charge.

I was looking for a replacement since the fans were loud... Is it because this unit has the potential of using more power?
I could google it, but since you mentioned to not do it this way I figured that you may have real life experience. Thanks!
This particular inverter is overkill for what you were using it for. You're better off getting a 100 to 400w inverter, depending on use.
A way to eliminate the inverter is to get a 12v dc "splitter". A 3 way works best. The newer ones have multiple usb ports for charging plenty of devices.
The key is to get a 10 to 15a fused splitter. This will allow you to charge more devices faster, and without overloading the circuits. (you still need to know the total amp surge draw.
Some laptops have very high surge rates, and can draw 80w plus while running.
In this instance, you will need an inverter. Again, you need to know the watts being used / needed.
Living off the grid is a perfect example of what works better.
For most of us using an inverter in a vehicle / boat / atv, etc is a short term solution to a short term need. Just plug in and go.
This class of inverter is designed for the budget conscious and ease of use and convenience. Small electronics, lighting devices,charging batteries, emergency lights / uses. If you have a big enough alternator(s) or enough batteries, you can do anything including welding with these things.
But whatever you use it for, (my fil loved that I had an electric blanket in the car for him) and especially this size and up inverter, make sure it has either an audible battery alarm or an automatic cutoff switch, because these things will deplete your battery quick if the engine is off. And some will deplete your battery with the engine running!
This is why some professional Ham radio guys have multiple alternators charging multiples of batteries.
Will the cars engine be running? I'm thinking you have your reasons, lol
If so, put in 4 deep cycle marine batteries and and extra alternator, and hook up, say a 4 to 5k w inverter?
With the engine off, at 900w, you will drain huge marine batteries in a very short time. And probably burn up the pump from the lack of amperage.
A better solution would be to get a portable generator if the engine will be off.
Other options require an rv type setup.
Honestly, these type of inverters are over rated. This particular one is 1000w max.
Realistically, it may do 750 to 800, but will incinerate itself if the current draw stayed there.
The max rating is helpful in trying to figure out what size inverter you need for a max surge draw. An ac unit would be repeatedly surging.
