Given the X1 Yoga 2017 charges via its USB C/thunderbolt ports, I was wondering whether I could pick up a power bank to charge the device on the go
Can anyone recommend a power bank that has enough juice to recharge this laptop? (doesn't have to be a full recharge) I'm not really sure what I'm meant to be looking at when it comes to power banks, let alone ones that are intended for laptop recharging

But the Yoga 2017 charges via USB-C, and none of those options seem to have USB-C output?
Ohh sorry for the miss, then try below options:
I guess first one will be ideal for your requirements.

This is NOT a power bank (Battery), but if you happen to be interested in a good portable AC supply to take on the road:
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 month 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 $35 in black. You can check it out on Amazon here.

That looks interesting - how much bigger is it than the 65W charger that comes with the laptop? Amazon says its 1 x 1 x 1 inches, but that doesnt seem correct as it'd make it a cube...

It's about the same volume, but a slightly different shape. It's not as long or as thick, but it's taller. They both use the same AC connector/cord, which you can't see in the less than wonderful picture I just took of the two next to each other:
Hope this gives you a reasonable idea of the size. 1"x1"x1" would be nice, but as you suspected, is not the case.

Hi - I've got an X1C5 2017, i.e. USB-C power, but expect its charging requirements are the same as the X1Y2.
Has anyone found a USB-C powerbank that definitely works with either X1C5 and X1Y2?
I'd prefer one from Lenovo, but they don't seem to sell one, so am looking for a reputable brand. There are lots of 3rd party USB-C power banks available now, but it's not clear to me which will support the X1C voltage/power consumption. I can see the links in this post but it doesn't say whether anyone has tested them.
BTW according to the cases on my 2 Lenovo USB-C chargers they output:
* 45W: 2.25A @ 20V
* 65W: 3.25A @ 20V
(they have 15V & 5V outputs too but presumably it's the 20V one that matters)

There seem to be very few outputting 20V. This looks promising:
ZMI USB C Power Bank 20000 mAh
There's only one comment on there at the moment but that person says it works with PixelBook & X1 Carbon
The user manual at https://files.xiaomi-mi.com/files/zmi_10_powerbank/Zmi10%20EN.pdf
says: "Output voltage: MAX 45W; USB-C 5-20V / MAX 40W" so slightly less than the X1C might need.

I've just ordered a "ZMI Power Bank Unit - BLACK 217438201" for my X1C5. I'll post back experiences here: https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/USB-C-PowerDelivery-PowerBank-X1-Yoga-2nd-Gen...
