Review on BatPower CPD2 High Power Delivery 120W USB-C Laptop Car Charger: Compatible with New MacBook Pro Air, HP, Dell, Razer, Surface & More! Dual USB QC3.0, DC 12v-24v Auto Power Supply by Jeff Westra

I have used this product about 10-15 times with a Mac PowerBook 15" and when it works it works fine. But after about 30-45 minutes of use it overheats so much that it welds so the moving part ends up being welded to the plastic body and no longer works properly. I replaced one at the company but the second had the exact same problem. I had with 120w (90w on USB-C connection) 87 watts are apparently not enough for Mac consumption.
