I've measured the "loading behaviour" of quite a few uUSB (and other) PSU's so you might find that of interest: http://www.cpmspectrepi.webspace.virginmedia.com/raspberry_pi/MoinMoinExport/USBPowerSupplies.html However, w.r.t. the Pi Zero, given that it is most likely to be used only with a small n...

Difficult to tell from the ebay photo, but I don't see any active regulator -- it wouldn't be necessary for powering LEDs . So probably not good enough for a Pi. Also: Output voltage: DC5V 2 - 4A（max） power :10W MAX 5V2A = 10W, so 4A is not compatible with 10W. Someone who wrote that spec doesn't u...

I suspect that that "sort of thing" will not be well enough regulated - why not use a standard uUSB connected PSU (remove the uUSB connector and wire directly to the appropriate GPIO pins) + inline fuse? (The O.P.'s reference to "freeing up" a uUSB connector may be a "red herring" as that's "power ...

Do you really mean a 2A 5V transformer (ie. an A.C. device - I hope not)? I would suggest that a 5V 2A DC PSU needs a fuse rated at <=2A (to protect the PSU) but a fuse rated <=1.5A might be better (protection) for the Pi Zero. What type of fuse were you thinking of? Trev. Hi, Looking at this sort ...

Hi, Sorry for dragging up an older post, but it is relevant to my question. I have a Pi Zero & would like to power it from a 2A 5v transformer, via the GPIO - my question is what fuse should I put between the transformer and the Pi? The Pi is to run OSMC or Kodi, with the HDMI out to TV and a Wifi a...
