If your device is rebooting or showing the USB PD power to continually connect and disconnect, please check your USB-C cable and power source.
If your power source or USB-C cable is not rated to carry the full load that the Rencher Industries USB-C PD adapter is capable of carrying, you may see a warning of an overload, or the device may continually start and stop.
USB PD is still generally new, and not all devices are cross-compatible. You may need to troubleshoot by swapping out links in the chain and rule out the problem by process of elimination.
Since there are almost an unlimited number of batteries and power supplies available to plug our USB-C PD adapters into, you will need to check with each one that it can handle a load of 90 watts, continually.
