What I Found
I tested USB-C barrel adapters with a Decimator, Apple TV, iPad M1, Fluke meter, wall power, and several power banks.
I’ve been seeing more people use USB-C barrel adapters to replace the bulky DC power bricks that end up in tech bags, racks, and production kits. The idea is simple: carry fewer wall warts, use USB-C power you already have, and clean up the mess.
Yes, USB-C barrel adapters can replace some power bricks, but only if the voltage, amperage, wattage, barrel size, and polarity are correct. In my test, a 12V USB-C barrel adapter powered the Decimator successfully from wall USB-C power, and one Anker power bank worked too.
