another option to get full 45w charging is the xiaomi gen 3 20000 mah power bank
cannot. it does not have PPS
it has static V. To achieve 45W, the V needs to be variable.
I have this powerbank. While it worked for my Switch and Surface Pro, sadly its charging the Note10+ at 15~20W (which is not bad)
sidenote, i have another powerbank which i can charge both Switch and Surface Pro. I use it to charge Note10+, the screen says fast charging. but the charging time is normal charging time (compared to xiaomi). when i measure the output, its only charging at ard 5~7W. how is this fast charge? and how come Note10+ can display "Fast Charging" but in actual its only 5W?
