My cigarette lighter plug or more common a outlet for a 12volt tv is listed as 10 amp. Well 12 volt 10 amp is 1200 Watts more than enough amp to run a 400 watt inverter. I run my 400 watt inverter of that plug all the time. The inverter power my TV and also a Vornado Fan at the same time. Your face plate should on plug should tell amp rating.
As another poster pointed out, your amp/watts draw is wrong. Take the antenna booster loose from the wall. You will see that depending on the year model and brand of the Antenna booster, they use VERY SMALL gauge wires to the actual back of the cigar outlet. Just because the amp rating is 10 amps, the FEED wiring and fuse in the RV fuse panel may be 15 or 20 amp supply fuse. SMALL gauge wiring CANNOT safely flow the higher 12 volt amps that even a 400 watt inverter draws. Doug
