Hello, I could use some help with the math on determining if I can run a particular multi-charger made for three P4P batteries and the controller off of my car cig lighter jack and a 600 watt, heavy duty Bestek inverter. The photo attached shows the charger I use routinely in the house to charge my three batteries up after a mission. I need to take it on the road and want to run it off the inverter, but my car cig lighter jack says 150 watts maximum. I assume more draw than that and the car pops a fuse. The charger only says Output 17.5 volts/13.5 amps (branch output 17.5V/4.5A). I don't know how to tell how many watts the charger will be pulling from the cig lighter and would it make any difference if I charge just one or two batteries instead of three at a time as I do in the house? I think the Inverter is up to the task and can certainly handle one of the single chargers that comes with the P4P, but will the multi charger pull to much for the car to handle? Thanks and appreciate any suggestions.
