Step 1: Pick the right charger 

  • For two high-draw laptops, use a 140W PD charger. 

  • Lower-watt chargers still work, but total power will be lower. 

Step 2: Plug in the right ends 

 

  • Single USB-C end → wall charger 

  • Two USB-C ends → your laptops 

Step 3: let Smart Power Sharing do the work 

  • The cable shares up to 140W total across both laptops. 

  • The split isn’t fixed; it adjusts to each laptop’s demand. 

  • If you connect one laptop first, it may receive a larger share. 

NOTE: If one laptop reaches 100%, the other can draw more power.
