Is the USB Power Delivery a Game Changer?

October 28, 2013

The first USB PD devices will come to market in 2014, with a “big roll-out” in 2015, says Brad Saunders of Intel. Gregory Reed, of the Swanson School of Engineering at the University of Pittsburgh, calls the new USB standard a “game-changer”.

This is an extract of an interesting article from The Economist related to the USB Power Delivery: The humble USB cable is part of an electrical revolution. It will make power supplies greener and cheaper.

Anyone interested on USB-PD and in general on new technology should read.

USB Recharge port on HP Chromebook 11: One port to rule them all

October 14, 2013

A newborn  just enter entered in the always growing family of Chromebook devices: the HP Chromebook 11.

What captured my attention is the unusual charge solution: not anymore hp-chromebook-11-micro-usba dedicated jack to connect an external charger, but a microUSB, as described by JR Raphael in his review. Like our portable devices, smartphones or tabled. This is a great news in my perspective, at least for two reasons.

Standardization

It is the first step to standardize the recharger mechanism: no more custom and proprietary jacks and charger, but an universal main adapter with USB connection compatible with all our device, hopefully with more then one USB port to recharge many device at a time. One Ring to rule them all. This will impact the final price of the device, too.

Power Flexibility

A single connector will simplify our life. But soon users will ask to have more flexibility. To recharge batteries in a faster mode delivering more power and to use this port to recharge portable device as well, or to supply external peripherals. In one word, USB Power Delivery technology. Able to deliver up to 100w over USB cable.

Dreaming

This device is the first step in the direction of simplifying our life among different and proprietary chargers, jacks and connectors. I hope to see more device implementing this bold solution with a step forward toward USB power delivery and more peripherals and devices taking advantage from this technology.
