I am trying to find a portable battery that can support the iPad Pro 10.5 Fast Charge with USB-C.
I have done some testing with wall chargers and power banks and I have found that some chargers actually discharge my iPad. The only products I have found that work are the Google, Apple, and Anker wall chargers. Of course, the 29W Apple charger is the fastest at around 3900mAH.
DBPOWER’s Wall Charger and iMuto’s Power Bank discharge my iPad at around -1400mAH so when I walked away, I saw that the percentage of my iPad has decreased. I also made sure it was charging by clicking the power banks button and still had the same result.
Anker’s current PD Bank is shown on Amazon to output 22.5W of power, but I’ve also seen people say 30W.
Can anyone confirm which answer is right?
