  • Three USB-C ports each deliver up to 140W single-port output

140W Three-Port USB-C Charger

This 140W GaN charger supplies up to 140W from a single USB-C port and powers three devices at once. It targets users who carry a high-power laptop, a phone and a tablet and want one compact brick for all of them. The dot-matrix screen shows live wattage per port with adjustable brightness and orientation. 5th-gen GaN circuitry keeps the unit 47% smaller than the original 16-inch laptop charger.

Pre-Purchase Power and Cable Check

Confirm your laptop accepts 28V/5A over USB-C to reach the 140W single-port rate. Verify that each cable you plan to use is rated for 5A and supports PD 3.1; the charger ships without cables. Check that your wall outlet provides 100-240V at 50/60Hz, which matches the charger's input specification. Ensure the total simultaneous draw of your devices does not exceed the 140W combined ceiling.

Desktop and Travel Integration

The charger measures 2.5×2.3×2.3×1.5 inches and weighs .56 lbs, so it fits in a small bag or sits on a desk without crowding outlets. Three USB-C ports replace multiple single-port adapters and free up two wall sockets. The screen can be dimmed or turned off for dark rooms, and its orientation flips for horizontal or vertical placement. Multi-port splits such as 67W+30W+30W or 45W+45W+30W keep a laptop, phone and tablet charging together.

Questions about this item

What comes in the box and do I need to buy a cable separately?

The charger ships with three USB-C ports and a dot-matrix display; a USB-C cable is not included so you must supply your own.

Which port should I use for a MacBook Pro 16 that needs the full 140 W?

Any single USB-C port can deliver up to 140 W at 28 V 5 A, so plug the laptop into whichever port is free.

What does the 140 W rating mean when I connect a laptop and phone together?

With two devices the charger splits power as 100 W + 30 W or 67 W + 67 W; with three devices it divides as 67 W + 30 W + 30 W or 45 W + 45 W + 30 W.
