| Dec 2, 2016 at 11:14 | comment | added | goldilocks | @ppumkin I believe the Pi 3 is different from the others in that it's 2.5 A max although of course it doesn't need that much for itself. However, it does seem to be distinctly more finicky to me WRT supply. Not that this really solves the problem here. Except I'll add the 4th or 5th observation re, yes some cables can drop 0.5+ V. | |

If the wire inside the cable is as thick as one hair from your head then there is no way the voltage will get to the Pi properly. If bought that cable from chinese bazaar then that wouldnt surprise me. Go and use a cable you got with your smart phone or with some other device you got it bundled. Those work well but are usually only capable of 1A or 2A MAX. But that is OK because the Pi is 2A max. Test the current on the other side of the cable | |

| Dec 2, 2016 at 9:50 | comment | added | Ghanima♦ | Hello and welcome. Here's a little more about the flash but I guess that is not helping too much. Since you expect the Pi to be responsible and not the wiring (there are really bad micro-USB cables out there - so don't rule that out yet) - try to measure the voltage on PP1, PP35, and PP7. | |
