Charging Goal Zero Yeti from outlet in truck bed

I'm looking to grab a Goal Zero Yeti 1500x for camping/overlanding with my truck. I was curious if anyone else charged their's while on the road via the AC outlet toward the tailgate in the newer Tacomas. I have one in my 2021 TRD Off Road and was curious if that would be the preferred method over 12v inside the vehicle. Are there any risks of one over the other?

 

I use a Bluetti EB3A. On my FJ Cruiser, I ran a heavy wire set from the battery, through a fuse, and to a 12-volt outlet I installed in the back. While driving, the Bluetti charges, and also powers my

$699 Iceco VL45 ProS Portable Refrigerator, Multi-directional Lid, Dual USB & DC 12/24V, AC 110-240V, 45L Steel Compact Refrigerator Powered by SECOP, 0℉ to 50℉, Home & Car Use [Upgrade, 47 Quarts]

Iceco VL45 refrigerator. When I set up camp, I plug the refrigerator directly into the outlet, and the Bluetti is free and fully-charged for use - charging phones, lights, my CPAP while I sleep. Typically, the car battery shows about 12.5 volts in the morning at the back from the outlet, and the Bluetti is at about 45 percent charge.
I am really happy with the setup - simple and effective.

I would GUESS that the power loss from converting 12 volts to 110 and (typically) back to 12 volt for the fridge is not huge. I do see some risk from having 120-volt power if things get wet. I tried the Iceco in my Tacoma when the truck was running, and had to do the high-wattage conversion to get the fridge to run.

 

You'll need to install a 12v outlet in the bed in order to charge your goal zero while you're driving. My factory AC bed outlet wouldn't charge my ecoflow river pro while driving due to it dropping down to 100w.

 

I found that my EcoFlow Delta 2 wants pure sine A/C to charge with or it won't even start charging. The Toyota inverter is not pure sinewave like say a RedArc is.

I also modded my truck with the 400W anytime setup, so I know it isn't because of the 100W issue.

My Jackassery 1000 didn't care what you fed it, but it would top out at 168W input.

I have a dedicated fused 10awg 12VDC line ran to the back seat in my double cab where my EcoFlow and ARB fridge reside. The EcoFlow charges off this line, and the fridge runs off the EcoFlow.

If parked for days, the EcoFlow gets switched over to solar charge.

 

You could go with the the dedicated 'Yeti Link' system and charge directly from the vehicle battery. I've installed dozens and they work great!
