I have a PowerCore III Sense 10k and it’s awesome, but I’m finding an issue with the USB C charging. When I use the provided USB C cable (on both sides), it charges my OnePlus, but other devices like Skullcandy Ultra Push or speakers, it doesn’t seem to charge them. I have to connect them via the USB A port. I don’t really understand why this is happening. Any ideas? Am I missing something about USB C?
