Well kinda wurkking... and I need help from you EE gurus.
So I added two 5.1 K Ohm resistors to my Wurkkos FC11 - see them on the two middle "CC" posts bridging to ground in this image:
And the great part is that I can make the charging lights light up and it will draw current from a PD charger through a c-to-c cable:
BUT... it's intermittent for some reason. The charging lights (and indeed the ammeter I use to test) go on for a few seconds and then turn off and the cycle continues. It is delivering a charge - just on-and-off.
So far I have yet to cook anything. The PD charger will still fast-charge my phone and an a-to-c cable will still charge the light!
If you except from cheap chinese flashlight to support PD protocol. No way
Most of that USB-C powered flashlights just used 5V VBUS voltage to charge battery. They not support at all QC 2.0 or QC 3.0, same as PD. Also PD need to communicate with charged device to send commands to charger via CC pins. So in your case charger don’t know what to do. Just use regular QC2.0/3.0 or 5V output USB charger. They will work without problem.
Now I understood you try to force charger to work in 5V 3A mode with that resistors if I am right?
Something similar problem is discussed over Ti forum
I don’t want them to support the PD protocol. I want it to charge off a PD charger through a C-to-C cable. AND I’m willing to pay for it. I’d get the Fenix PD36R or the Magicshine Mod 20 (both support PD charging) but they’re too big for my taste.
I’m the OP and yes I did it with my Wurkkos FC11 and it’s been working great. I added the two resistors and aside from tricky soldering I got it to reliably charge in 5V 3A mode. I could be wrong but it looks like it steps down amperage as voltage increases during charging and at the end of the charging cycle it shows a green indicator and amperage drops to zero.
And best of all it works great and charges from any PD charger I try.
Supporting PD charging costs literally pennies and makes charging an EDC light very convenient in a household that has moved past USB-a.
