12VDC charging supplies about 40 W to the Jackery while the power converter brick can output 24 volts @ 3.74A (up to 90W). AC charging is faster. You just have to remember to turn on the inverter each time you start the engine.

Also running a dometic (55IM w/ insulator bag) with a knockoff 600Wh battery pack.
From the 12v I get about 25-30W with a USB-C Cable and the 110 with the battery's brick puts out around 90W. My battery can dual charge via DC plug and USB-C so 120W total. The fridge averages 60W draw and about 30% duty cycle on most days in CO that are around 70-80 deg F.
Notes from my experience:
1) On my 2015 SR5, If I push the inverter button and shift to drive too quickly the inverter will kick off. I have to let it sit for about 30 sec for the battery draw to normalize (I think at least) and then I can drive and charge without interruption. I cannot turn the inverter on while driving which I attribute to the draw being over the 100W limit that the 4Runner puts out while in Drive.
2) If the fridge goes into idle mode and doesn't kick back on for 20-30 min the battery will shut off the 12v socket as it doesn't have any draw. I think most battery generators have this feature. To get around this I have an led light string plugged into the usb socket of the dometic. These lights keep the battery from shutting down and serve as a a visual indicator that the fridge it still running.
3) The 55IM has too much power draw to be run off of the 12v on its own. It continuously gave me a compressor startup error when I had it configured this way.
