need 12v 30a aviation/rv output to cigarette output adapter

I’m new to off grid. I have an AC300 with 3 B300k batteries. I need to run 2 x12/24 volt items (EcoFlow wave 3 AC and IceCo fridge). I found a cigarette splitter that has 15amp fuses and max capacity 300w. I’d rather not use it. Also, I think the 2 devices together will exceed the 10 amps supplied by the outlet. I’d like to use the aviation output because I wont be using it for anything else. I have the IceCo on the 24v cigarette outlet. The Wave3 is on an AC300 AC outlet. I’d like to move it to DC. I have the Wave3 battery and it comes with a cigarette to XT60i charge cable. The battery docs say you can use it with solar, cigarette, or DC to DC charger.
Maximum Input 1000W Max,
Solar Input 11-60V⎓13A Max, 400W Max,
Car Input 12V/24V⎓8A Max, 200W Max
Is there an aviation outlet to cigarette outlet adapter OR an aviation direct to XT60i input adapter out there (so skipping the car adapter part)? My googling is not turning up anything. I’m scared I’m going to fry my Wave 3 battery even if I find one unless its super reassuring and newb friendly documented.

No, your Cig socket outlet is 24V @ 10A if total load at 24V exceeds 10A, the AC300 is in overload.

I’ll leave @Bluetti Admin to give you 30A RV cable options. However, Aviation to ZT60i is far better than introducing a Cig plug/skt in between.
