Review of a tester extracting the functionality of USB-C cables
www.getusb.info USB-C Cable Tester Sets the Bar High •

USB-C has firmly established itself as the universal connector standard, integrating data transfer, power delivery, and video output into a single interface.

What's the best way to add a battery like device to a dynamo light
  • Your solution may very well also work, good thinking. A few things to consider though:

    • Putting capacitors in series requires balancing them
    • A silicon full bridge rectifier drops ~1.4V frm the input
    • Incandecent bulbs require a lot of current to get going, this may result in a delay for them to turn on
  • Has anyone ever seen a "10A" USB-C cable and can tell what their purpose is?

    The video dissects a USB-C cable marked with a 10A rating even though there is no such rating in the standard.

    It would be interesting what this is meant for, as I've never seen a device with such a rating?

    What's the best way to add a battery like device to a dynamo light
  • I've actually done that with a simple single diode rectifier and a supercap with zener voltage limitation:

    If your supercap has a too low series resistance for the LED to light immediately you need an additional resistor in series with it. It is simple and small enough to directly fit inside the original lamp casing and has been working without a problem for over 3 years.

  • Some basic info about USB
  • The USB-C standard and particularly the USB PD (power delivery) is so complex it almost feels comical.

    The PD standard document (freely available on usb.org) is over 800 pages long and features a lengthy part about the role of the cable alone which is mostly hidden from the user. Here's a short video about this issue: https://www.youtube.com/watch?v=6bZ0y9G-4Pc

  • Test of three different original apple USB-C cables

    This video tests three different cables, ranging from cheap to really expensive and explains the differences between each other

    There is a lot of variance in regular USB-C cables

    Any real cable testers besides the one featured in this video?

    The USB-C cable tester in this video looks really good, but it seems to be unavailable for now: https://ble.caberqu.com

    Are there any alternatives I can buy right now?
