I bought a couple of
lamps off amazon but unfortunately the USB C ports don't really work. Most of the devices I plug into it either don't charge at all or complain that something is wrong with the connection. The USB A ports work fine so I imagine the problem is that the power supply does not support USB PD so the device isn't able to negotiate charging correctly.
Here's a picture of the case of the power supply:
And the power supply itself:
A few questions:
1. I was thinking about replacing it with
this 5V 3A power supply. Would this work to power both ports or do I need something with PD capabilities for the USB C port to work?
2. Would there be any issue powering both ports with this 3A supply (compared to the 2.1A supply that was already there)?
3. From the picture you can see that the single output is wired to both the USB A and C ports. Does that make a difference for what kind of power supply I can/should use? (I could of course wire them up separately but I'm trying to avoid doing so.)
Any help/suggestions are greatly appreciated.
