So did a bit of testing today.
And the Rpi works better with the standard iPhone than the newer bigger iPad pro charger.
That bigger charger says 20 Watts and 5V with 3A's
I looked at the official wall wart for a Pi and that says 15 W and 5V and 3A's.
The iPhone charger is usb A and the iPad charger is usb C.
With the same specs that charger should work, yes?
It doesn't even start up with the bigger charger, wtf!
Is Apple lying with the specs on their chargers?
Or do I have one of those Pi's as suggested by Old P?
[ As an aside, it is well known that the original version of the RPi 4B lacks critical resistors in its USB-C interface and, specifically, wouldn't boot with iPhone USB-C chargers. This was corrected in a later board version. I don't think this is the specific cause of your issue since your RPi4B by itself boots with your iPhone charger, although this may be only because of the "funny" cable which likely isn't e-marked. ]
Time for an official Pi wall wart!
I'll report back when thats in.
At the moment I doubt that this is ever going to work in my car.
