The heat my cigarette lighter inverter puts out is outrageous, meaning it is wasting battery power.
Well that be the problem...
First, running an inverter from ANY cig lighter plug is wasting energy, period.
Cig light plugs are terrible high resistance connections, never meant for continuous high power draws. Typically limited to 8A or about 80W and then you are risking a meltdown of the plug.
Then add in typical cig light outlets are wired with very light ga wire and there can be a lot of that wire in between the socket and battery.
All of that drops the battery voltage that the inverter gets to see under medium to heavy loads. The voltage drop MAKES the inverter WORK HARDER which means the output stage HAS to dissipate more heat than it should.
Either hard wire the inverter using HEAVY ga wire directly to the battery (best) or at least install a new cig light socket (if I remember correctly there is some Marine type cig sockets which have better contacts) with a dedicated heavy ga wire run directly to the battery.
