I have a 45w usb c PD Jackery power bank that I picked up from Amazon and it charges my XPS 13 9370 just fine. I think any 45w usb c PD power bank should work but this is the only one I've tried.
Edit: Link to the battery pack I ordered Jackery SuperCharge 20000 PD, USB C 45W Portable Charger 19200mAh Power Delivery Power Bank with 45W USB C Input & Output for USB C Laptops(e.g. New MacBook), Nintendo Switch, iPhone 8/X [link]
if you want a good battery for on the go this thing is a beast. It will rapid charge (power delivery). Its actually the only one i've found that puts out enough juice to convince my nintendo switch doc it's plugged into the wall adapter. It can even charge usbC laptops like the newer macbooks. Holds like 3/4 full phone charges.
One down side is it doesnt come with its own rapid charger but ironically the nintendo switch charger fills it very fast. (even though it can't charge the pixel itself, usbc is weird).
I'd highly recommend getting a proper PD-compliant battery, like this: [link]
You'd be able to charge rapidly while using your PixelBook, and it's more future-proof. At 45 Watts, you can charge most PD laptops either quickly or at a reasonable rate.
I tried the Zerolemon, didn't work. You need a 45W PD 3.0 charger. This one worked well for me.. I got the Titan X but that one doesn't seem to be sold anymore and this one looks like the same thing, but with a slightly smaller capacity.
What's so special about it? 405 g... that's what all these batteries are, more or less. The Mara is going to be 320g at 18000 mAh with two USB C ports (45,15) and Qi but not USB A.
The Jackery Supercharge is 19200 mAh and claims to be 430g which is very odd because the 26800 mAh also claims to be 430g. Nonetheless: 405g is nothing to be excited about. Did I miss something...?
Actually... I got this Jackery USB PD power bank today and I can confirm it will charge at 45W. It'll charge the system while it's on, too.
Yes it will work, but I wouldn't risk damaging your X1C with a no-name battery pack.

USB C charging was such a mess when the standard was first released (former Nexus 6P owner) that I'm still leery of using any charger that's not from a well-known brand. Most of the issues have been resolved, but there are still products available that aren't compliant with USB C Power Delivery or with the USB C spec in general. Granted Lenovo has protection circuitry built-in to protect against bad chargers, but I still wouldn't want to risk damaging my laptop to save a few dollars.
Is it a USB-C? If it is, they make USB-C "PD" chargers for chromebooks and laptops. They typically put out 30-45 watts.
There's one on sale today on Amazon check r/NintendoSwitchDeals
This looks like a good option: https://smile.amazon.com/Jackery-SuperCharge-Portable-19200mAh-Delivery/dp/B0791BCKCS
It looks like the listing even has a coupon you can enter at checkout and it comes out to $59.
For the Pixel 2, you'll want to look for Power Delivery. The Qualcomm Quick Charge or IQ won't offer the "fast charging" you need for the pixel.
