Be careful of any electronics from harbor freight. This is the cheapest Chinese stuff.
Look closely at the specs. It says up to 87% efficiency.
I would cut that number down and assume it’s more like 50%.
Check YouTube for reviews of harbor freight inverters.
If you are using the vehicle’s starting battery for this project be sur to monitor battery voltage to make sure you don’t draw it down so far the vehicle will not start.
There are devices (battery savors) that will cut off load when vehicle battery gets to low

I didn't know batteries tasted good.
Don't fall into the trap of getting an inverter that is a lot larger than what you need. Inverter efficiency starts at essentially zero for no load and goes to a maximum near rated load. If you get a large inverter and run a light load, you will suffer from lower efficiency. That probably wouldn't matter if you keep the van running but then you have a major efficiency loss in the van.

What about the EverStart brand from Walmart?

As I said, I don't know specific brands.

Is there a reason you're not looking at just wiring in a couple 12 volt led lights where needed? They're super efficient and use little power. You can also wire in a usb outlet on the same circuit to run your laptop and charge a cell phone.

getting direct dc power led would make much more since.
I just assumed you already had the 110v led on hand. but it would be cheaper to get new 12v LED instead of using and inverter
unlese you had other 110v devices to run

I have a small inverter with a power strip mounted to charge various small items in the van (laptop, rechargeable canned air/blower, etc. The lights were free, and I have an idea to secure them. I need a new inverter anyway, so it will solve everything. Everything has to be only functional when the van is on. I will add a second power strip to act as a master light switch.
