Multiload : 140W Electronics Load with PD support and Volt Amp Watts Meter
This variable load can be used to monitor and test power supplies. It supports PD to control USB fast chargers. Non USB power supplies can be connected to the load using 4mm banana plug leads.
I will currently handle up to 140W, however it is easy to add more TIP122 Darlington transistors in parallel with the existing four to increase the load capacity further, with a suitable heat sink and cooling fans if desired.
There is a series of videos on Learn Electronics Repair describing the development of this load.
Start here (links to all the development and testing videos are linked in the video description to this one). You will also find shematics and source code linked from here

It can be used standalone, or with an external USB analyzer or current meter, however there is an optional daughter board that adds Voltage, Current and Watt meters to the load. You can download the PCB for the daughter board separately
