A USB C to USB C cable should still work. Anker even sell some charge-only ones (or at least, they're only USB 2 inside)

- bartvk 6y agoAs far as I know, a USB-C charger should never have a hot V+/V- and that is what my beard trimmer requires. EDIT: alias_neo corrected me, and pointed out that it's D+/D- I'm thinking about. On the other hand, this is expected behavior for a USB-A charger, and thus for a USB-A-to-C cable.
- pantalaimon 6y agoThe USB-C Madness never seems to stop.
- auxym 6y agoWait... How does it charge if it does not supply voltage?
- bartvk 6y agoAnother poster on this same level provided the info! I made an error.
- alias_neo 6y agoPerhaps you mean D+/D-? You won't get very far if V+/V- aren't supplying any current.
- bartvk 6y agoYeah I think you're right! Updated my comment.
- cesarb 6y agoActually, V+ (the correct name is Vbus) not supplying any current is the correct initial state for a USB-C socket. It instead provides a small current on each of the two CC pins (usually through a pull-up resistor on each pin), and only after it detects that the other side is drawing that current (usually through a 5.1kΩ resistor to GND on each pin) will it supply power on Vbus.
- fbrozovic 6y agoYour beard trimmer is likely missing the 5.1k resistors to GND on the CC pins, which enables the USB-C charger to output 5V. I had several devices (mostly flashlights with integrated battery chargers) that would only charge using A-C cables. After adding the resistors, C-C cables also work.
- bartvk 6y agoProbably, yes. I could do some soldering on the beard trimmer, but the electronics in the earbuds are positively microscopic.
