I'm a total newbie here so please be gentle.

I'm thinking of using a Raspberry PI and a USB drive to make a NAS, but I'm worried about the way the PI gets its power. It looks like the power plug being mini micro USB could disconnect due to the slightest accidental wiggle.

Is the power secure? If not, can it be made more secure somehow?

  • micro usb, not mini.

It is plenty secure the tolerances on the two mating surfaces (cable and socket) make for a very tight friction fit. There are also small tangs that mate making the joint even more secure.

If you are having problems with the power cable coming dislodged, I would try another cable, as this should not happen.


I definitely agree with what steve said; this should not be a problem, and to try another cable.

But in some cases, it's not the cable's fault. For example, my Pi is in a 3d printed case. The combination of poorly fitted porthole and blocky plug on the wire made it fall out easily.

I would reccomend getting creative with some duct tape(assuming you have a case, you definitely don't wanna tape it directly to the Pi :) ).

But, first definitely try to find a cable that stays better,

    I would argue that this is a problem with the design of the case and you would be better off modding the case or trimming the bulky plug. Than trying to jury rig it with tape. Feb 19, 2014 at 17:17
  • True. However, I was just using what I had on-hand at the time; I didn't have anything to cut out the plastic of the case with, and I wasn't comfortable cutting into the plug of my power supply.
