The most powerful USB-C charging
This page lists the products whose highest watt figure is 140W or more. They are for the laptops that draw the most power over USB-C, such as the 16-inch MacBook Pro, which Apple supplies with a 140W adapter, and for desks where one charger runs a laptop, a tablet and phones together. Charging this fast over USB-C came with USB Power Delivery 3.1, which raised the voltage to 28V for 140W, 36V for 180W and 48V for 240W. Before it, the limit was 100W.
What is here
- GaN chargers from 140W to 200W with a UK plug, from three-port wall chargers to six-port desktop chargers with a display. See 140W USB-C laptop chargers.
- Power banks from 140W to 170W, several with USB-C cables built in and a display showing the charge left. See laptop power banks.
- USB-C to USB-C cables rated 240W, some with a small display showing the watts flowing, which is a handy check that the laptop is charging as fast as it should. See USB-C to USB-C laptop cables.
Getting the full power
Three things must all support the higher power: the charger, the cable and the laptop. The cable needs to be a 240W one, which the USB-IF marks with a 240W logo on certified cables; an ordinary 60W cable will hold the laptop back. The laptop must support the higher voltages itself. One that does not simply draws the 100W or less it is made for, which is safe.
On the multi-port desktop chargers, the figure on the box is the total. With several devices plugged in, it is shared, and one port gets the full figure only when it is used alone. Read the port-by-port figures on the product page if you plan to charge a 140W laptop alongside other things.
Questions people ask about 140W and over
Do I need a 140W charger?
Only if your laptop's own charger is 140W or more, or you want to charge several devices from one plug. Check the watts on your original charger's label.
Can I fly with a 140W power bank?
What matters on a plane is the battery's watt-hours, not the watts. Up to 100Wh is allowed in hand luggage without approval; from 100Wh to 160Wh needs the airline's approval. Check the Wh printed on the power bank. Our guide to charging a laptop on the move has the rules.
Is a 240W cable safe with a smaller charger?
Yes. It works with any USB-C charger and carries only what the charger and laptop agree.
