Rpi 4b in to Topping D10 for car audio (airplay)

So

1) by itself, the RPi4B boots and runs successfully with the iPhone charger

2) once booted by itself, the RPi4B continues to run when the D10 is plugged into it

3) but the RPi4B won't boot successfully with the D10 already attached? 

PS - I hope Zandvoort has been spared the flooding that has occurred elsewhere in the Netherlands this summer.

Correct! So more power it is!
I’ll start with the iPad charger for testing and when needed upgrade to the official power supply.
Will this still work in my car with a usb charger from the sig light thingie later if it needs that much power!?
We’re on the West Coast and not a drop of Rain here!
Beautiful beach weather.
The floodings are near the German border.
Really weird such a big differance in such a small country.
Thanks for caring!
