DC power for 2nd gen thinkpad X1 yoga?

is it possible to power this product from a cigarette lighter?  I can't find any adapter products to do it?

Simply, no.  The power supply needs to put out 20V and 3,25 amps as well as sending the control signals to tell the laptop what is being sent.  Your cigarette lighter won't do that.

The Google turns up a couple of things.  One claims 90W the other 45W.  No personal experience, so FWIW:

Re: DC power for 2nd gen thinkpad X1 yoga?

too bad...i really wanted to buy the system.  what a poor design and limiting for a mobile device.  my last two laptops were lenovo and i've used them in the field with 12v adapters.  Tell your engineers they should rethink the design (i worked at intel long enough to know about that stuff)

Re: DC power for 2nd gen thinkpad X1 yoga?

It isn't the laptop design.  ThinkPads have all needed 19V or 20V for many years/models now.

 

The IBM/Lenovo AC/DC adapters could make 20V from 12V but I don't think there's currently a USB-C version.

 

Perhaps one of the ones I linked will serve.   There may well be others out there - I didn't look too far.

 

For the record: while it won't help with the Gen2 X1 Yoga that's USB-C only, some other current-model ThinkPads can charge via USB-C or Slim Tip and can use existing Lenovo 12V adapters.

Off the top of my head... of the latest models the TP Yoga 370 and TP P40 Yoga (I'm uncertain of the P40's wattage requriement).  If you go back one generation, the X1 Yoga Gen1, TP Yoga 260 and TP Yoga 460.

 

Anything that uses the rectangular slim tip - and doesn't requre more current than the adapter can provide.

 

An example of a currently-available Lenovo 65W DC adapter:

And a 90W AC/DC unit:

 

https://pcsupport.lenovo.com/ec/en/solutions/migr-72900

 

If you try to find that last one - 41R4493 - be careful.  Many on-line sellers will take that to mean any of the AC/DC units, and they don't all have the rectangular tip.  Prices are all over the map.  I found one but it took considerable searching.
