Precautions:

1) Since the new Mac book current output is around 1.0A,the computer will start self-protection when the load exceeds 1A. It will prompt: USB power consumption is large,disabled,the converter is unplugged (and the disable icon is turned off or Reboot) Re-insert, first insert PD power supply (connect a hard disk and other power-hungry devices,when there is no normal connection,please connect the charger to the Type-C socket of the product to power the computer,hard disk,etc.)

2) When the PD adapter is inserted and removed,the connected USB device will be quickly disconnected and then restored within a few seconds.To prevent data loss or damage, avoid disconnecting the PD adapter from AC power while transferring data.

3) Heating problem: The converter is made of aluminum alloy, which has good heat dissipation performance and long service life. During the use of the product, the internal energy conversion occurs, and most of it will be dissipated in the form of heat energy, resulting in heat generation. The temperature is generally normal and can be used with confidence.
