I'm an amateur astronomer, and the power tank that I use to run my equipment is on the fritz, so I want to use my 150W inverter to run the following at a remote site:
- A laptop (~20W)
- A telescope mount with 2 motors (20W max, about 6W typical)
- 2 cameras, 1 with a cooler (maybe 10-15W during the cooldown period, a few W ongoing)
So, 30-40W max, less for the great majority of the time, 2-4 hours. Power inverters usually have about 80% efficiency, so about 25% higher than that out of the battery. I could unplug the laptop and adjust settings so it runs off its internal battery.
My plan is to plug the inverter into the 12V outlet, crack a window and run an extension cord to my equipment maybe 20 feet away. My question is, will doing this damage the 12V battery? I have a 2017 MS 75D, and I have never replaced the 12V battery.
