I am going on a long road trip with a buddy soon and I was going to use a power inverter that plugs into the cigarette lighter socket of his car so I could use my laptop while we drive. I'm trying to match up specs to make sure everything will work safely together but I'm not sure if I'm reading the labels correctly.
All of the reviews for the inverter swear up and down that this will work, but when I dug into the actual specs for the devices involved I'm no longer sure. My assumption is that I should be matching up the input and output ratings so that
car out >= inverter in and
inverter out >= laptop in but the numbers don't seem to make sense that way. The cigarette lighter fuse is 10A but the inverter in draws 28.5A so shouldn't that be way too high? But if most lighter fuses are in the 5-20A range how does this device have so many positive reviews? Instead, if I'm supposed to be matching outputs does that mean the laptop's 10.3A vs the inverter's 2.6A is a nonstarter?
So, in short:
- Would this setup work?
- Cigarette Socket: ???V 10A ???W out
- Inverter: 11-15V DC 28.5A in, 110-120V 60Hz 2.6A 300W out
- Laptop: 100-240V 3A in, 19.5V 10.3A 200W out
- What is the correct way to read these specs so I can figure this out on my own in the future?
