what makes RC allen business machines so special. It features a compact, low-profile power brick and multiple power ports to accommodate even the largest of power supplies. And because it’s not designed to be throttled down, it has no external power supply. That means you can get more juice out of the machine than you really need. The machine has 70% more power than it needs in the funny little design that doesn’t need a plug so you can save precious space on your desk.
