Comment on The EU common charger : USB-C
ekky@sopuli.xyz 10 months agoI’m do not understand why it would not be able to charge with a X to USB-C.
As far as I’m aware, even if one of the two connected devices (such as charger and flashlight) doesn’t have a proper chip for agreeing on voltage, it will just default to 5v. The only thing that should prevent that is a damaged (as in no + or - connection) cable. Even if the data connections are damaged, it should still charge in slow-mode.
Needless to say, I have never experienced that problem even with cheap china cables/chargers, except, of course, for damaged cables.

For c to c cables, the devices need to be able to communicate with each other to establish which one is the host (the charger in this case). With a to c cables, the type a side is assumed to be the host by default. You’ll often find that manufacturers of cheaper devices prefer not to spend the extra money to implement this technology, though some will, and in fact allow for even more functionality. For example, one of my flashlights does have that chip, so it can both charge from a c to c cable if a charger is detected, and also automatically act as a power bank if I connect a device to it such as a mobile phone.

The technology you’re talking about is literally two resistors - parts that cost less than a cent a piece when you get a few hundred.

All I’m hearing is potential savings $$$
