CELLAIRIS AC Adapter 140 W 6 ft Cable

SKU CH-M3B4-4TY33

A 140 W USB-C PD 3.1 GaN charger with a 6 ft cable delivering up to 90% efficiency in a compact, cool-running design

  • 140 W output powers laptops and tablets quickly
  • GaN technology raises charging efficiency to 90 %
  • 6 ft cable gives flexible desk placement
  • USB-C PD 3.1 support enables fast charging
  • Compact GaN design runs cooler and saves space

High-Power GaN AC Adapter

The Cellairis 140 W charger uses gallium nitride technology to deliver efficient power conversion up to 90 percent. It targets users who need rapid charging for power-hungry laptops, tablets and phones from a single compact wall unit. The 6 ft cable adds placement flexibility on a desk or nightstand. This adapter suits anyone consolidating multiple bricks into one high-output solution.

USB-C PD 3.1 Charging Standard

The adapter supports the USB-C Power Delivery 3.1 specification for negotiated high-voltage output. Devices must implement PD 3.1 to draw the full 140 W; older PD versions will negotiate lower power levels automatically. Cable length is fixed at 6 ft, so the AC plug must reach an outlet within that radius. No other output interfaces or legacy barrel connectors are provided.

140 W Output Capacity Headroom

The 140 W ceiling comfortably handles large ultraportables, creator laptops and dual-device charging scenarios. Headroom disappears when multiple high-draw devices request maximum power simultaneously, forcing the adapter to split current across ports. It is not for users whose combined device draw exceeds 140 W or who require DC barrel-output compatibility.

Questions about this item

Is the 140 W output a single port or split across several ports?

The 140 W rating is the total power budget; the adapter uses GaN technology to deliver efficient conversion up to 90 % across multiple high-power output ports.

Will 140 W actually charge my laptop at full speed?

It supports USB-C PD 3.1 fast charging, so any laptop that accepts 140 W over USB-C PD 3.1 will charge at its maximum supported rate.

Does USB-C PD 3.1 cap the power lower than 140 W in practice?

USB-C PD 3.1 allows up to 140 W, and this adapter is rated for that full 140 W, so the standard does not limit the output below the stated figure.
