The biggest laptops that charge by USB-C
Until 2021, USB Power Delivery stopped at 100 watts. The PD 3.1 update from the USB-IF added higher voltages, 28, 36 and 48 volts, for 140, 180 and 240 watts, called the Extended Power Range. A 140W USB-C charger uses 28 volts to reach it. Only the largest USB-C laptops ask for that much: Apple's specifications, for example, say the 16-inch MacBook Pro fast-charges from a USB-C power source of 140W or more. Every charger here has a UK three-pin plug.
What you will find here
- 140W GaN wall chargers with two, three or four sockets. Those that list 28V among their USB-C outputs can give 140W from one socket.
- Chargers with a display of the watts, temperature or charging time.
- Desktop charging stations of 175W and 200W in total, with four to six sockets. On these, the strongest single USB-C socket gives up to 100W, and the total is for charging several laptops, tablets and phones at once.
How to choose a 140W charger
Decide which job you want. If one laptop needs 140W, look for a charger that gives 140W from a single USB-C socket: the output list in the description shows 28V at 5A, or says 140W single-port. A charger with a big total and no 28V output will charge that laptop at up to 100W, which works, more slowly.
If you want to charge everything on a desk from one plug, the 175W and 200W stations do that, and each laptop on them gets up to 100W. The descriptions give how the power is shared when several sockets are in use.
The cable is part of the chain. For 140W, the cable must support the Extended Power Range: a cable rated 240W. A 100W cable holds the charger to 100W, and a 60W cable to 60W. See USB-C to USB-C laptop cables.
Questions people ask about 140W chargers
Is a 140W charger safe for a smaller laptop or a phone?
Yes. The charger only steps up to a higher voltage when the device asks for it, so a phone takes a phone's power.
Do I need a special cable?
Yes, for the full 140W: a USB-C cable rated 240W. Below 100W any cable rated 100W or more will do.
My laptop came with a 140W charger. Will a 100W one do?
It will charge it through USB-C, more slowly, and it may not keep up under heavy work.
