  • Has 3 ports: 2 × USB‑C + 1 × USB‑A 
  • Maximum output: 65 W when using a single USB‑C port 
  • Power sharing / distribution (when multiple ports in use): e.g. USB‑C1 = 45 W + USB‑C2 = 20 W (when both used) 
  • Broad compatibility with fast‑charging standards: PD 3.0, QC 4.0+/3.0/2.0, SCP, FCP, PPS, AFC, Samsung 9V2A, DCP, Apple 2.4A etc.

  • Safety features: Protection against overcurrent, overvoltage, overheating, short circuit, interference, flame-retardant shell, etc.
