More R&D on my Anker Nano 10000 mAh power bank!

I did some more research on my new Anker Nano 10,000 mAh power bank.
I drained it completely to 0% and then started charging it with a 60 W USB-C Anker charger while monitoring it with a WITRN C4 USB monitor.
When I started charging it at 0%, after a couple of minutes, it predicted that it would take another 1 hour 27 minutes to get to full charge.
For most of the duration it continued to charge at ~30 W and as it got closer to 100%, charge rate started dropping progressively.
Even after getting to 100%, it continued to accept charge at ~5 W for another 15 to 20 minutes.
It completely stopped accepting charge i.e. the charge rate dropped to <0.5 W after 1 hour 39 minutes.
Even though it’s a 10,000 mAh power power bank, to charge it fully took 18,869 mAh / 37.075 W hour. I know there are charging losses involved but I didn’t think it would be 1.8x the required charge.
Wanted to share my nerdy experiment.
