Pi 5 Low Power - Anker 747 Charger (GaNPrime 150W)
November 18, 2023, 19:29
I'm getting a message that the Anker 747 Charger (GaNPrime 150W) is not able to provide 5V 5A power. Anyone else have this issue? Is there a recommended power supply that can power multiple (3+) Raspberry Pi 5's?
I'm also getting the same message with the Anker Prime 67W GaN Wall Charger (3 Ports)
I get the message with both the Anker USB-C cable as well as a USB-C cable used to power a MacBook Pro (Intel).
I don't have them all plugged in. Just using one is causing issues. 😦
the reason why none of the chargers are providing your Pi's with enough power is because the Pi uses 5V 5A, which is not a part of the USB PD Standard that most if not all Power adapters adhere to.
The Pi needs a specific 5V 5A Power Supply, since this configuration is not part of that standard.
I am using the official one and it has been working well.
The chagers you have are theoretically able to provide 5V 5A, but since its not part of usb pd, the highest they can deliver for 5V is 2A
oh man...
thanks for the insight. that totally sucks.
lol
nothing you can do about it outside of getting a psu that works for the pi
it is what it is
yeah, going off of the charger spec sheets I couldn't tell for sure if 5v was capped or if it had options to up the amps. I should have checked the USB PD specs. It didn't occur to me that this would use a non-spec USB-C power profile. 🤦♂️
I'd assume they did it for cost saving purposes.
if you wanted more power but also stay within spec, you'd have to have hardware on the pi to shift at least some of the power back down to 5v.
I'm no electrical engineer tho, no clue how much that would work out to in cost.
oh well. thanks again. you saved me a lot of time and more hair pulling.
