Review on ⚡ Zendure 100W USB-C Wall Charger, Superport 4 Laptop Power Adapter with Dual PD Ports (100W&18W), Dual Zen+ USB Ports 18W for MacBook Pro, HP XPS, iPhone 13 12 11/X, iPad Pro, Samsung S10, Switch - Silver by Elizabeth Brooks

As mentioned in other reviews (which I read after originally purchasing the device) it *doesn't* support 100W charging on the first USB -Connect and charge something too, or via a second USB-C port. USB PD allows the device to adjust voltage and current. This device limits the voltage of the first port to 5V (up from 20V) when the second USB-C port is in use, effectively limiting the first port to 25W (USB-C maximum current is 5 amps) when both connections are used.
