Does this power connector has a standard name? How is it called?
I checked on the wikipedia and complete USB section knows nothing about such connector.
I'm a very mobile person and travelling about 180 days per year in different coutries. Needed the car charger for my brand new Y3P, but local distributor could not help me with that (either could Swedish distributor).
I tryed to find it on lenovo page, but it seems to not give me any results. Is there car charger for Y3P available at all?

Lenovo 40W Slim travel Adapter (UL)
Part number: GX20H34904
Here’s all the info. I don’t know about a car charger.

Link doesn't open.
But this part number works in search now. It's weird though, that if you open shop and go to Yoga 3 Pro laptop section and open accessories - there is no charger under there (neither the link to this product).
But I still need the car charger. I'm on the road most of the time.

@Lenovo, when does the Yoga 3 Pro power adapter finally become available in Switzerland as a spare part?? Still waiting to be able to order it for over 3 months...

I am in similar situation as you. I blew my IC.
Do you know which wires you applied the 20v too? Is it the White and Black?
Also Do you know where your tech shop got the new IC to replace it with from where?
Thank you for your help.

Unfortunately, it looks like the power regulation circuit is not isolated from the main board. I'd have to evaluate the circuitry, but from the below photo, it looks like there are 5 pins coming off the yellow USB 2.0 charger port. Without metering the pins, and given that the connector isn't USB 3.0, I'm assuming the extra pin is the 20V bus. If you applied 20V to the 5V bus by mistake, there's a good chance you fried the controller for several USB ports.
Unfortunately, again, there is no way to repair this. The likelihood of being able to source the exact IC, having a proper rework station, and a steady hand is very unlikely. You'll have to source a new motherboard, or get Lenovo to repair it.
I sympathize with your situation. Lenovo won't tell you the IC, but you can look for burn marks on the motherboard. If you find them, you can post a pic here and I can identify the IC on my board if it's printed on top.
