TL;DR
- Android 15 is preparing to tweak the threshold that determines whether a charger is seen as fast, from a measly 7.5W to a more reasonable 20W.
- The operating system has long considered any charging speeds of at least 7.5W to be fast, which is far, far below what actual fast chargers can deliver nowadays.
- The change isn’t live yet in the latest Android 15 beta, though, so chargers that deliver 7.5W of power will still be seen as fast on Pixels.
I think they meant they plugged the battery bank into the car’s phone charger?
How does that tell them the wattage output of the power bank
Maybe they have a wattage reader on their charger/power bank/car?
I assume they meant check the wattage of the car charger output. some powerbanks have displays now and can show you it’s input or output.
… All phones also have displays and should show you the same thing but don’t.
