Review on Ultimate 120W USB C Car Fast Charger - Dual Ports for 🚗 Lightning Fast Charging - Compatible with Laptop, Tablet, MacBook, iPhone, Android, and More! by Esvin Hopuhnopuhlis

This product does not appear to have sufficient heat dissipation capacity to provide 100W of continuous power. Used my laptop (Dell XPS 17) connected to it for about two hours. It worked fine for the first 30 minutes, then it started turning on and off, and finally it just stopped charging and the blue light ring around the USB-C port went dark. There was a strong smell of burnt plastic and the device was too hot to touch. Given its size, I doubt it's malfunctioning, I just don't think it's big enough to handle a continuous 100W load.
