Why it stands out

  • Full-speed laptop + 2 more devices. USB-C1 delivers the complete 140W (28V/5A) to a 16″ laptop, while USB-C2 and USB-A keep a phone and earbuds charging at the same time — something a single-port 140W brick cannot do.
  • Compact for a true 2C1A 140W unit. 78×77×30 mm / 0.35 kg (~180 cm³), smaller than comparable 2C1A 140W chargers.
  • Up to 93.25% efficiency at 28V/5A (single-port, 100% load); EU ErP (Reg. 2019/1782) compliant.
  • Universal protocols: USB PD 3.1 / PD 3.0 / PPS / QC — MacBook, iPad, iPhone, Galaxy, Steam Deck.
  • Certified safe: IEC 62368-1 (CB Scheme) + CE + RoHS + ErP, with OVP / OCP / OTP / SCP and CB-tested fault auto-shutdown.
Higher power density than comparable 2C1A 140W chargers 0.78 W/cm³  (≈400 W/kg) — about 13% above comparable 2C1A 140W chargers (≈0.69 W/cm³).
