Etron Technology announced a usb power delivery solution which can deliver from 10w to 100w over usb, which can largely reduce charging time. EJ888, Etron Technologys' latest USB Power Delivery (PD) Controller IC, is based on the USB-IF's USB Power Delivery Rev. 1.0 specification, USB-IF Battery Charging 1.2, and optimizes user mobility by allowing data transmission and power delivery to be combined on a single USB cable. Etron will demonstrate EJ888,along with its comprehensive series of USB 3.0 controller ICs, on CES 2014

"USB Power Delivery will help simplify the lives of consumers by providing a single-cable for data and power delivery up to 100 watts," said Jeff Ravencraft, USB-IF President & COO. "USB-IF member companies like Etron that incorporate USB PD into products and solutions further the efforts toward universal charging."

"For early market engagement, Etron's latest USB Power Delivery Controller IC EJ888 is based on the USB Power Delivery Rev. 1.0 specification. In addition, it supports USB-IF Battery Charging 1.2 for any portable device. The EJ888 Chip enables higher voltage and current in order to deliver power up to 100 watts, with 20V to the full 5A, via USB. Utilizing bi-directional power delivery, EJ188 automatically detects current sources and sinks, and performs a negotiated handshake via VBus. It allows users to access simple Plug-and-Charge via USB and meets the needs of USB PD developers," said Dr. Nicky Lu, Etron Technology Chairman & CEO.

My Lumia wants that handshake stuff!

Several time in my life, I have been USB sapped, from silly things, like grabbing with my hands a plugged camera that was downloading pictures into the PC, connecting cheapo USB sticks, etc.

Now with a much higher amperage, I don't know if I have a long life to live.

you get shocked from usb devices? what?

unless your touching the inside of the usb connector, you shouldnt get shocked. even so, current isnt high enough to deliver a painful shock.

This is good news for desktop users, but I doubt laptops will get this controller.

I think he was dragging his feet across the carpet and mistook static electricity for the USB drive shocking him...

 

To get shocked there needs to be two points of contact, and a path between them for the electricity to travel.

This is a pretty cool thing to have as Asus' AI Charger doesn't really work on my Z87 board. Just need to get this implemented on boards but having 5A of USB power is a bit overkill imo.

I was not wearing shoes, with my feet on the ground. Lifting the camera connected to the PC (usb). Touching the bottom of the camera, that has the contacts to plug it on a printer (old camera). got sapped happened a few times to me, because I kept forgetting

If they had this in the 60's FIdel Castro would be dead.

Yup, that is definitely not the USB port shocking you, that is either the camera itself or static electricity. The USB cable should be able to dissipate any energy the camera is creating, so it still falls back to most likely being static electricity.

 

Now-a-days (basically ever since we discovered that grounding is actually important in like the 80's), the only way to shock yourself on electronics is to be doing something you shouldn't be doing like sticking it in water, or opening it up when powered.
