If you guys are going to pull any current on these never use ones that don't attach directly to the battery.

Most are not. Look for "name brand" car inverters and most are not pure sine wave.

Also most people don't need one to be.

I bought one of these from Amazon all the way back in 2016 and it's still going strong to this day.
