1991 318i M42 max watts from cig lighter

[terryalmeida787]

Hi guys, Does anyone know what the max wattage of the cig lighter is if I got a power inverter? I looked at the diagram and it has a 30 amp fuse (but shared with a few other things), so 30 amp x 12v cig lighter, would it be 360 watts if nothing else was drawing? I'm sure it's gotta be less but how much less, and how could I test it? Thanks! Sent from my SM-G981U1 using Tapatalk

Look up the wire size in the ETK and determine max amperage from that.
