Hi, my partner and I did a van conversion recently and have been traveling in it. I purchased several DC USB-C Chargers up to 60w to charge my MBP in the van. To my surprise, none of them work. I have previously charged this same new MBP in my 4runner with one of these same charges (older 2005 4runner) but for some reason I cannot charge my MBP in my van or in my new 2020 4runner. Is anyone else having these issues? Why sell 12V car chargers and claim to charge MacBooks if it's not possible?
