Powering using cigarette 12 socket

[Graniterich]

So I recently bought a 500 watt bluetti, think jackery if not familiar. Have a conventional 12 35 Amp sla, battery switch, solar controller, which is switched as well. Seems to me that you could disconnect battery and solar input, plug portable power cigarette cable male to male in an emergency to run the trailer leds and such.

Any comments?
