140W USB-C GaN Charger with Dot-Matrix Display
This 140W USB-C GaN charger targets professionals and travellers who need fast, simultaneous charging for a laptop and two smaller devices. Three USB-C ports support PD3.1 and a wide range of legacy protocols. A built-in dot-matrix screen shows real-time wattage per port with adjustable brightness and orientation. The unit is new and ships in black.
Three-Port Power Distribution and Limits
Each USB-C port can deliver up to 140W when used alone, with voltage steps of 5V, 9V, 12V, 15V, 20V and 28V at 5A. Dual-port combinations split power as 100W+30W, 67W+67W or 30W+100W. With all three ports active the charger manages 67W+30W+30W or 45W+45W+30W, keeping total output at 140W maximum. The dot-matrix display reports the exact allocation so you can see when a port drops to its lower share.
Replaces Bulky Single-Port Bricks for Multi-Device
The charger replaces a single 140W laptop brick and separate phone or tablet adapters, cutting carry weight to 225 grams and volume to roughly 47 percent of the original Apple 140W unit. It is not suited for buyers who need more than three USB-C ports, require a barrel-connector output for legacy laptops, or want an integrated cable. The jump is worth it when you regularly charge a high-power laptop alongside two other USB-C devices and value the on-screen power readout.

Questions about this item
Will the DELL S2U-Black 140W USB-C GaN Charger power my older MacBook Pro 16-inch alongside a phone and tablet at the same time?
Yes, the charger has three USB-C ports. Each port can deliver up to 140W alone. With three devices connected the default split is 67W+30W+30W, so a 16-inch MacBook Pro can still receive 67W while a phone and tablet share the remaining ports.
How can I verify the DELL S2U-Black 140W USB-C GaN Charger is delivering the correct wattage to each device after I plug them in?
The built-in dot-matrix display shows real-time wattage for every port. You can cycle brightness through high, low or off, and rotate the screen orientation to read it easily whether the charger sits on a desk or a power strip.
What cables come in the box with the DELL S2U-Black 140W USB-C GaN Charger and what must I buy separately?
The package includes only the charger unit. A USB-C cable rated for 140W or 28V/5A is not supplied, so you will need to provide your own cable for each device you want to charge.
