@eric102 interesting man! You mind sharing/linking what barrel plug to cig adapter you’re using with that charger you linked above?? Or did you just snip that female cig port part off and attach a barrel plug??
And you said it wasn’t getting hot either?!? That’s awesome.
I just used a car cig adapter plug from one of my other Bluetti’s. The brick does get pretty warm but not crazy hot like the Lenovo.
@eric102 gotcha! I’m tempted in getting one of those and just snipping off that cig port end, and soldering up a barrel plug. Sure that would help the resistance and heat impact even more? 
thanks for sharing man
No. The AC and all other power stations have set limits as to the allowed input levels. I don’t recall what that is on the AC30, but it is closer to 100 watts than 400.
