Other projects • Re: Raspberry pi 5 UPS with 12v Buck converter

This does work. I am using a 12v 3A dc cig lighter input.
Just remember to put

PSU_MAX_CURRENT=5000

in eeprom config. WIthout that it wont work.
It seems:

[config.txt]
[all]
usb_max_current_enable=1

may also work.

I have turned on 'usb_max_current_enable=1'
through raspi-config, but still shows power supply not able to provide 5A error at startup. But no low voltage warnings.
I haven't added 'PSU_MAX_CURRENT=5000'

Can you please share which Type C cable you are using ? Longer ones are having voltage drop for me.
