I would suggest reading this recent thread.
As stated by notebookcheck, "the X280 just has one 48 Wh internal battery".
I find this examination of power delivery negotiations on a Huawei Matebook as well as the other reports listed on gtrusted to be exemplary of the issues. This shows the variety of power delivery scenarios any USB-C Power Delivery controller will negotiate with the device's USB-C implementation. The Huawei Matebook uses a non-standard USB-C PD implementation, and there are plenty of reports of incompatibilities with various chargers.
So far the common thread in reports of USB-C PD charging incompatibilities seems to be undersized power supplies. The comment made by Anker on their 26800 w/PD may simply be that the device is underpowered for the charging negotiation.
The x280 has the advantage of having ports to the Thunderbolt 3 standard. I would simply find one that advertises PD capability in the range of 45 watts, and preferably one that has the full range of voltages offered by standard Power Delivery.
This is a newer product and I haven't seen it under other brand names, worth some research: EMIGVELA
Portable Computer Power Bank 20000mAh 20V 45W, Type C and USB Quick Charge Mobile PD PowerBank. Advertised as 74 watthours. What's advertised would charge the x280 close to 2 times although I'd suspect more like 1.5x.
This is a rebrand of the Worldpower 40,000. Worldpower is big in Japan. You can find useful reviews.
Kayo Maxtar is a battery manufacturer with some interesting products, containing USB-C PD is the Maxoak K3. Maxoak K2 is a massive battery pack with 20v output and I have used it extensively via solar charging to power a 13" Acer. Their capacity and wattage ratings are not inflated BS.
Suaoki has just fielded a new 100 watthour device.
If you fly, I believe 100 watthours is the limit for in-cabin batteries... something to keep in mind.
Personally I am reading reviews and trying to determine the actual manufacturer of a lot of these devices, figure out how they are constructed and what sort of component they utilize, because I need to solar power mine. When you can use an AC adapter it pretty much comes down to picking one large enough to feed 45 watts. Potentially, the voltage negotiation of an x280 might want a 20v connection and some of the smaller units provide 5v, 9v, 12v only.
Since the USB-C PD standard includes a 100 watt connection, you can imagine the implications of feeding 5 AMPERES through a USB peripheral cable... you'd want 18 or 16 gauge wire for that. I still don't understand that myself. However, a 12, 15, or 20v connection feeding 2 or 3 amperes seems rational enough. So I'd simply find a good looking unit, search the Amazon reviews for reports of success with various laptops, and try one out.
Personally I favor 20v DC input to laptops, so much less complicated.
The one thing I would avoid is a AC plug on a battery bank. Plugging in your AC adapter to a power bank that is generating a high power sine wave... it's gonna be lossy and noisy as fuck.
Really good question. Short answer: https://www.amazon.ca/Krisdonia-50000mAh-External-Portable-Smartphone/dp/B076FSPHKL/ref=mp_s_a_1_5?keywords=Krisdonia&qid=1564425618&s=gateway&sr=8-5
It's tricky, when you program the light animations each light draws 0-60mAh (at max bright) so you have to program patterns that are efficient on battery
