The dock won't charge the K1 by itself. You still need the charger cable to make the connection between the dock and the wall socket.

 

Can you buy a new cable from the Russian Lenovo website?

From the Lenovo US accessories site: (checked the Russian portal and it doesn't seem to have the same many shopping options...)

 

Lenovo 18W AC Adapter

Part number: 78Y7365

 

http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/catalog.workflow:item.detail?GroupID=38&Code=78Y7365&category-id=4364BD0F20B94413B5AD6E684D2848E9&hide_menu_area=yes#learnMore

 

Here are the indications on my adaptor: (US model, but should work in Russia or anywhere with 220V with a travel adapter).

 

Model ADP-18AW B

Lenovo part number: 36200005

Input: 100- 240V ~ 0.4A 50-60Hz

Output: 12V 1.5A LPS

 

Good luck. Let us know what you find out.

Another thought: have you tried using the USB transfer cable plugged into a USB car charger adapter? I haven't tried it myself but I read from another post that this may work.

You can not charge over USB. (most tablets can not)

These things are higher voltage than USB (which is 5V)

I think the k1 charger is 20V and you can't turn 5 (or even 12) volts DC into 20 without some significant gymnastics.

The charger output is 12V 1.5amps.  A few tabs run off higher charge ratings - for example, the Iconia Tabs run on 12V as well - except they use a more standard 3mm coaxial plug.

 

I have been trying to find a source for the K1 connector, but have not been able to as yet.  Someone on another forum found a source for the Thinkpad connector, so I would think the Ideapad should be able to be sourced as well, but have not found it as yet - it has an unusual pin setup (34 pins).

 

If a source can be found, it would be a matter of pushing 12V through the correct pins, so the source could be any 12V DC (min 1.5 A).

 

Does anyone know the part number/source for the connector?  Most tech equipment will source parts rather than go fully proprietary as it's cheaper - especially for dev purposes.

Wow, that looks a lot like a K1 plug!

 

If it really is, and if the power leads extend to the USB connector, you'll still need an AC adapter delivering 18v at the correct amperage and polarity to plug the USB into. Plugging the USB into a PC's 5v USB port would, at best, only "trickle charge" the K1 - if it does anything at all.

 

If it's a K1 plug, and if the data lines extend to the USB connector, it can be used as a client data cable, like the one that came with the K1. IMHO, THIS IS MOST LIKELY WHAT THIS IS, AND THE SELLER IS CONFUSED.

 

If both the power leads and the data lines extend to the USB connector, it can be used in both of the above ways.

 

If the correct pair(s) of data lines are swapped, it's a host cable.

 

It'll cost you $12.99 to find out for sure. Good luck!

That looks just like the regular USB data transfer cable, which does not actually charge the K1.  I'll bet their description is incorrect.  As mentioned before, there is no practical way to get 12V with sufficient power from a 5V USB connection.
