Looking for RPI 4 quality PSU

Fri Sep 25, 2020 11:20 pm

I’m looking for USB-C PSU for RPI4
There are lot of options and I’m aware that the recommended is the official. I just wondered if anyone came across something with better quality and can recommend please


I have couple of Apple USB-C charger 18W, can it be used?

You ask for “better quality”. What specifically are you after, that is “better”?

I've been using the official PSUs ever since the Pi4B came out. They're well made, reliable, and inexpensive.

I'll give you a "probably" on that. Depends on when you bought your Pi4B and what you use for a cable. It's also far more expensive than the official PSU. If you have any issues when using the Apple unit, pretty much the first thing anyone is going to say is "get an official PSU and get back to us if the problem persists", so it's better to start with the official PSU from the beginning.

What can be better than the power supply actually designed for the purpose?

Thanks!
Sure it’s by far more expensive, I just have couple of those Apple 18W USB-C available ;) so I thought to make some use of them

If you have them, try them. No damage to RPi4B or the Apple PSU.

After running the stress tests, you may use this command to detect any voltage (or temperature) problems that occurred since the last boot:

Code: Select all

vcgencmd get_throttled
it should always return 0x0 for a happy Pi.

I monitor the +5V pin on the header when I try a new adapter and cable. I will attach a USB powered hard disk as a sample USB load. I like to see that I never dip under 5V and that I have some tens of mV as buffer.
When you monitor at the header pin you check both the wall adapter and cable.
