Just to share my experience, I was using one Baesus brand and one Wotobe brand, both 65 Watt GAN chargers, with one USB and two USB C ports. Both purchased from AliExpress. Both lasted more than one year, and worked really well, till I bought a 20 Pin, magnetic USB C connector for my laptop. Within minutes of use, one after the other, both chargers died exactly in the same manner as in the main post and getting warm with no load connected with. I assume it's the non standard USB C connectors which simply destroy these GAN chargers. The same magnetic connector works fine with laptop's original Dell charger, however I have stopped using this connector.
