I don't know if this is the right sub forum to post in but this is my best guess.
So I recently ordered an Alienware m14x laptop. The charger it comes with is a huge and almost ridiculous 150 watt charger. I am planning on going on a 2 day road trip in the next month or two.
The dc power port on the vehicle I will be in has a sticker on all three of it's ports saying the maximum total power on all ports must not exceed 120 watts. Attached is a picture.
I have had a 90 watt laptop powered by a 100 watt power inverter plus a gps and two dvd players plugged in the other outlets at the same time without problems. So the total of the 100watt inverter plus all that other stuff was probably really close to that limit. I don't know how close.
So if I plugged in a power inverter capable of running my alienware laptop plus all that other stuff, what would happen? Would it blow a fuse? Would the alternator not be able to keep up? What would happen?
