New Power Supply for R5S

[bob]

My new power supply for my R5S just arrived! It's a TEKERA 11 Port USB 3.2 Hub with a PD 20W port.

In recent weeks, I've been getting numerous USB drive disconnects. I've got a 4TB USB SSD connected to the R5S. I've been using a 30W phone charger to power the R5S, its internal NVMe SSD, and its external USB NVMe SSD. The TEKERA Hub provides power to the R5S from the PD 20W port and also provides power to USB devices instead of them drawing power from the NanoPi. Copilot tells me the NanoPi USB ports can only provide up to 900mA, while the USB hub ports can provide up to 1500mA, and this might be why my USB SSD has been disconnecting. Time will tell.

The Hub USB connector has a little cap to convert from USB-C to USB-A, so it can connect to the NanoPi ports with no trouble. That wasn't shown in the images, so I wasted a few bucks on an adapter.

The power adapter is 12V, 5A, 60W.
The 7 x USB-A 3.0 ports support BC 1.2 protocol (USB Battery Charging Specification Revision 1.2), that's 5V, 1.5A, 7.5W per port.
The NanoPi USB 3.0 ports are 5V, 0.9A, 4.5W.


EDIT: Well, it appears I got my hopes up a bit too early. The damn USB drive has mysteriously disconnected once again.
EDIT: I replaced the USB cable that connects the USB drive to the USB hub, and it's been 71 days with no disconnects, no database crashes, no container crashes.

That new hub setup sounds like it should really stabilize your storage devices — way better power handling than the phone charger. Fingers crossed it finally puts an end to those random disconnects!

Good call on switching to a powered hub. Those USB SSDs can be pretty picky about stable current, especially when both the R5S and an external drive are drawing from the same supply.
