USB-C Charger Juices Up 100 Devices At Once
A DIY enthusiast known as [DENKI OTAKU] built a USB-C charger capable of powering up to 100 devices simultaneously using a modular design with stacked PCBs and dual high-capacity power supplies. The charger delivers up to 1.5 amps per device, requiring a total of 150 amps when fully loaded, and uses an open aluminum enclosure for cooling. While the build demonstrates a scalable approach for mass charging, questions remain about its long-term reliability under full load.

Aftermarket manufacturers eventually started making chargers with four or five ports which were great for travelling. But what if you wanted to charge even more devices? You might build something like this rig from [DENKI OTAKU]. The goal was to build a charger that could handle 100 devices at once. The charger is designed to charge devices at up to 1.5 amps. That’s no mean feat, as the device would have to be able to deliver 150 amps total when fully loaded. As for the actual design, though, it’s relatively simple.
