As explained, for other reasons I do not trust the author and I think the third explanation is likely. Yes, it claims to be 'regulated' - either the chip to do that is hidden, or the regulation relies on transformer design (not really regulated in terms of supplies for electronic devices), or someone is telling untruths, if not deliberate lies. You can even look for a few pictures that related to Raspberry Pi Zero Pinout pictures by scroll right down to collection on below this picture. The exactly dimensions of Raspberry Pi Zero Pinout pictures was 9. It will almost certainly not stay within the +/- 0.25V needed for a Pi. Raspberry Pi Zero Pinout Photos is match and guidelines that suggested for you, for ideas about you search. I cannot see a regulator chip - meaning that the PSU in question is likely to give out different voltages depending on the load. I looked at the photo of the product on ebay. I am understanding the bit about risking my Pi though!

Sorry David, I'm not understanding what you meant by the bit in bold? If the total design load does exceed 2A, don't let it all go through the Pi, the tracks probably won't take it. Add a fuse (preferably a polyfuse, as used on the other Pis) if the PSU can supply more than 2A. If you orient your Pi such that you are looking at the top with the GPIO on the right and HDMI port (s) on the left, your orientation will match Pinout. Pin 1 is the only pin with a square solder pad, which may only be visible from the underside of your Pi. Better to get a standard 5V 2A (or 4A) USB PSU and use the intended power socket. Pinout depicts pin 1 in the top left corner. Someone who wrote that spec doesn't understand what they are writing. ** links to some suitable examples of such can be found in this section of my webpages:ДҐV2A = 10W, so 4A is not compatible with 10W. the Pi Zero, given that it is most likely to be used only with a small number of USB peripherals (w/o the addition of a powered USB hub), I would use a powerbank** for its power (and charge that from a 'wall-wart' instead). USEFUL We benefit hugely from resources on the web so we decided we. I've measured the 'loading behaviour' of quite a few uUSB (and other) PSU's so you might find that of interest: The RPi Zero has the same pinout as the RPi1 Model A+, B+, and 2B. If these cheaper PSUs can be easily regulated to the required level, it seems worth a go to make a nice little enclosed box, rather than a 'wall wart' sticking out of a socket. That's really the crux of it - are the standard uUSB PSUs any better regulated? If they are significantly better and worth the extra cost, then it's not worth cutting the plug off. FTrevorGowen wrote: 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 only' and cannot thus be used for anything else)
