Also, when pasting Amazon links look for "ref=" near the item number. From that point on everything in the url is junk reference data. You can delete it to make the link shorter.
I can vouch for this guy as well as the 20000 mAh version here, both work great USB-C to USB-C for the Quest 2.
My understanding is that the internal battery will continue to drain if you use USB-A to USB-C, but I’m no expert. Both versions of the power bank I linked will ensure they get used up first.
