The USB-PD Programmable Power Supply (PPS) was implemented with USB PD3.0. With PPS, devices can gradually adjust the current ...

We’ve seen the first example circuit in the first article – a device-side (“upstream-facing”) USB-C port that supports USB 2.0 and 5 V of power. You must have the 5.1 K resistors ...

He spent 15 years editing the likes of CNET, Gizmodo, and Engadget. Previously, the USB-C Power Delivery spec tops out at 100 watts, and it’s definitely held the industry back a tad — for ...

In this case you can buy USB hubs that have an external power adapter required to boost the power or you can build a simple or complex circuit that can do the same thing. There are many usb power ...

USB has always been positioned as an external ... from connecting host to host (leading to the risk of a short circuit). Power flow occurs only from Type-A to Type-B, and thus with this current ...

but a control circuit will still be needed to ensure proper operation. The USB Type-C specification also specifies that the CC pins must also be able to deliver up 1 W to power the circuitry in ...

We were surprised to hear that he was unable to find a commercial USB power strip, but even if he had, it likely wouldn’t have had the bells and whistles that he added to his. The circuit went ...

The SnapPower charger doesn’t, however; it just replaces the outlet cover and adds a USB port below the standard power outlets. That means there’s no wiring involved — in fact, the only tool ...

and short-circuit protection. When you want to charge an iPhone, it’s best to go right to the Apple source for unerring compatibility. The Apple 20W USB‑C Power Adapter offers quick ...
