Cigarette Lighter max amps

hitch_hiker · Jul 13, 2020

Hi,

I recently bought without looking at power requirements Viair 85p air compressor (actually I did look, but forgot to verify it).
Based on it's specs the max draw is 15amp.
All cigarette lighter caps say 120w max, i.e. 10amp if I understand correctly. The fuse diagram for cigarette lighters states
15amp fuse.

Hence the question, did anyone try to use either similar air compressor or anything else that hits the limits of the fuse and what were the results ?

Thanks

Yeah, in my experience the fuse will only blow if you open the fuse box and look at the fuse. Better not to know for certain.

I have a Viair 70p which has the same Amp ratings as 85p. I having been using it for few years. No problem at all.

If it's an issue doesn't it also have alligator clips to use on the posts under the hood? I have the ARB portable compressor that I use off the terminal posts regularly to air back up after overland excursions - which have been several times a week lately

Almost same rating. At 40PSI 70p needs 14amp and 85p 15amp. Standard pressure for tires is 42psi

Well, to my shame (or luck ?) since I got car driving license 20 years ago never had to do it (attach anything to terminal posts).
The only time I had dead battery in car, it was at airport and there were "Certified car starter specialist" with golf cart and biiig battery.
