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.

I wouldn't waste the effort.
Only disappointment was finding no separate lugs for plug and clamps. So either wire up:
- Plug only, then limited to lower power
- Clamps only, then need hood open while using
- Both plug and clamps; most flexible but both remain hot while either is connected so have to jam the unused input into a plastic bag to avoid accidental fireworks.
A somewhat cheap feel but low cost, and it got me out of a bind..
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!
It's not a "does it work" scenario. It's more of a "is this efficient". It seems like most people were talking about using this thing as a backup power source, off batteries.
The larger the inverter, the larger the standby loss. So your 120w inverter may have 15 percent standby loss. The large inverters also have standby losses, just much more of it. Think leaving a map light on vs leaving your headlights on.
If your using it in the car while running, it's not a big deal. If your using it off a battery, then those losses are more significant.
A direct DC adapter to the Mac book is the most efficient way. Otherwise your going from DC to ac back to DC. Two transformers.
If your using it in your car once every month, it's not worth the hassle to buy special DC adapters. But if your running off battery packs (such as a RV or camping) this becomes more critical. The standby losses of a DC to DC adapter is very small under no load. Not the same for DC to ac.
How small? I'd say skip this and go find the alternator schematics. You need to build your turbine first. You'll need a voltage regulator if one is not included . It's also best to hook up to a battery bank of some sort, then run the inverter.
If you don't mind breaking some local nec codes, you can get a grid tie inverter instead. Then you can skip the battery, and will just offset the load used in your home.
Saving $30 when my other electroncis cost way more is not something I am willing to do.

People are quick to pick on modified sine wave but they are fine (usually) for electronics that use a power brick. Those transformers smooth the rough ac output and moves it back to smooth DC.

You actually don't even need an oscilloscope to check DC. You wouldn't see anything . Just a regular volt meter. If the voltage ain't fluxing, your good to go.
compressors and starting motors actually endure equally as much torture on a modified sine wave. the inrush current and where it is on the curve makes a difference.
the whole precision electronics... there are not that many. you may see distortion on things that use a direct ac output, but even most led LCD tvs use a power bridge, and if you have a 120hz unit, it doesn't really care if your input is 60hz.
that's why these have these transformers. very few things don't.
even with CPAP machines, your best off with a 12v DC adapter. it does great even straight off a car battery. don't need anything else.
Yes. We are. And the devices connected to the ac inverter, of which is the high dollar "sensitive" electronic.
It' has not been my experience of ac to DC electronic power bricks to blow at any more frequency on pure sine wave vs modified sine wave, and that the electronic devices are ultimately connected to said power brick which has smooth power output.though some have experienced otherwise. ..
that's why it's best to use a dc to DC.
