USB-C Laptop Power Bank 14000 mAh 40AL140CWW - worked once?

Hi all, got this power bank (40AL140CWW) for my P1. It is listed as acceptable for the system on the Option Compatibility Matrix (January, 2019). Got it a while back, tested it, worked fine: https://www.reddit.com/r/thinkpad/comments/9uyew4/fieldtesting_the_lenovo_usbc_14000mah_power_bank/

 

Using it today (charged yesterday) ... all four lights on the bank come on when I plug it into my P1, but, the system is behaving differently ... previously, the bank powered the unit and its LEDs went off one by one as the charge decreased; the main battery indicator on the bottom did not move off 95%. This time, the main battery indicator shows a decreasing level of charge, and so far, the bank still has four LEDs illuminated. Even weirder, the "remaining time" at one point seemed to indicate the battery was present (showing 8+ hours remaining) but now, even that has changed, and the system is acting like there is no power bank installed at all (shows 3 hours and 33 min [77%] remaining.) I am using the USB-C power cord that came with the bank.

 

Is it defective?

 

TIA,

tl;dr - called support, getting it replaced under warranty.
