X1 Yoga (2nd gen) Any 3rd party USB-C chargers?

I haven't yet found a single 3rd party USB-C charger that works with my X1 Yoga. Have you?

 

I thought USB-C was a universal standard so I am surprised and annoyed that I can only charge this machine with the original charger. Other USB-C laptops don't seem to have this problem:

Re: X1 Yoga (2nd gen) Any 3rd party USB-C chargers?

There is a standard negotiation that goes on to determine if the charger can supply enough power at the correct voltage. Many 3rd party chargers don't go through that communication correctly - they are simple 1-voltage power supply.  My Lenovo adapter can supply 5V to my USB-C cell phone and 20V to my laptop.  Having said that, I have an Incipio WM-PW-302-US that I got with a different device.  It works fine with my 5V cell phone and charges my X1 Yoga at 20V 65W

Well, I am starting to suspect it's Lenovo not following the standards. I've bought four different USB-C chargers from Amazon that were all well rated by buyers. None of them worked.

 

DO NOT WORK

Anker PowerPort+ 5 USB-C

AUKEY PA-Y5 5 port Type Charging Station with Qualcomm Quickcharge

Amavasion Type C PC Charger 3 in 1 with Dual USB C Ports and One Type C Port

 TeckNet 27W/5.4A Type C USB Charger

 

This is doubly annoying seeing as the battery life on this laptop is abysmal (sub 4 hours with very average usage.)

Don't worry, Lenovo follows the standards! The chargers you are trying do not support 20V at sufficient power levels. The lowest power level charger shipped by Lenovo with the X1 Yoga (2nd Gen) is 45W. richk gave an example of a third-party charger which supplies 65W.

 

To find USB-C chargers which will work, look for those which output 20V 45W at least (equivalent to 20V 2.25A). As you have discovered, there are 3rd party USB-C chargers which are aimed at different applications and do not support 20V at the required power levels.

 

Hope this helps!

Thanks for the reply. I wasn't aware that charging was all or nothing. I had assumed unit could charge slower if it couldn't negotiate a full input.

 

The power-rating on the chargers is misleading too. Several were rated as 60W or 65W watts but looking at the outputs they only support  USBC at 20V/1.5A!

 

I have ordered a unit rated for 20V/3A,  fingers crossed.

As I said above, the model listed in my earlier reply works fine with the x1 yoga gen2.

Re: X1 Yoga (2nd gen) Any 3rd party USB-C chargers?

As has been mentioned, the X1 Yoga (Gen 2) does properly support USB Power Delivery (PD) mode.

 

I wanted a different charger to use on the road and I wound up getting a third party (non-Lenovo) "RND 72W Smart Travel Charger with One Type-C (USB-C) Port and Three USB A Ports". The important part for me was that the USB-C port supported USB Power Delivery (PD) mode. It doesn't have a foldable (retractable) plug, it has a two conductor "shaver" type socket, and comes with a short power cord. I also have some US 2 prong AC plug adapters that fit directly into the "shaver" type socket, which I use in place of the cord depending on the location of the AC socket I'm plugging into. (Sort of like a huge wall wart)

 

This charger charges my X1Y 2nd Gen at the full 65 Watts just like the stock charger that came with it. It doesn't get hot (just warm). It also simultaneously charges my phone and my Kindle and my Bluetooth headset via the three USB A ports. I am very happy with it, and it has been serving me well for the many months I've been using it.

 

There are a number of third party chargers for use with our X1Y 2G computers. There are smaller ones that are only rated for 45 Watts that will work just fine, though it will take longer to charge your computer than with a 65 Watt charger. Just make sure the charger supports USB-C Power Delivery (PD).

 

I can only "recommend" the one I bought, which cost $30 in white or black.  You can check it out on Amazon here.

Thanks Billy
It's not quite enough to support PD mode. You need to check also that the 20V mode will deliver 2.25A or greater. Two of the chargers I tried had USBC PD certification and were 45W or higher but didn't work because they limited the amps on the 20V mode (maybe because they were multiport devices?)

True enough. Though I am surprised that the X1YG2 wouldn't take a lower powered "certified" PD charger.

Note that the one I recommended supplies 3A @ 20V (so it's really only 60W, not 65W), and simultaneous supplies 5V via the 3 USB A sockets.

It was exactly what I wanted, and works exactly as I expected.

I bought this charger listed above but it only worked for about 4 weeks before refusing to charge my Lenovo Yoga X1 2nd Gen any further.
