Laptop-level power
At 65 watts and over, a charger is no longer only a phone charger. This is where USB-C chargers start to cope with many laptops as well as tablets and phones, so one charger can do the lot in a bag, on a desk or in the car. This page gathers every charger whose own listing gives 65 watts or more as its top power. Everything here also appears on the 45W and over page.
What is here
Today that is a dual-port USB-C car charger rated up to 100W with USB Power Delivery, for the car's 12-volt socket. It keeps a laptop that charges over USB-C going on the road while a phone charges from the other socket. The 100W is the most it gives, shared between the two sockets when both are in use. More chargers join this page as they are added to wall chargers and car chargers.
USB Power Delivery at the top end
USB Power Delivery is the shared standard for fast charging over USB-C, written by the USB Implementers Forum, the body behind USB. Before its 3.1 revision it went up to 100 watts, using 20 volts on a cable rated for 5 amps. Revision 3.1 added higher steps at 28, 36 and 48 volts, for 140, 180 and 240 watts, for laptops and bigger kit. Phones use the lower steps, and a phone on a 100W charger takes only what it asks for.
The cable is half of it
Above 60 watts, the cable decides as much as the charger. Most USB-C cables carry 3 amps, which at 20 volts is 60 watts. To go higher, a cable must carry 5 amps and hold a small chip called an e-marker that tells the charger it can. Cables certified by the USB-IF show a 60W or 240W logo, so the rating is printed on them. If a cable's listing gives no rating, assume 60 watts. Several of the USB-C to USB-C cables here list 100W or 240W.
Questions people ask about 65W and over chargers
Will this charge my laptop?
If the laptop charges over USB-C, very likely, but check the watts on the laptop's own charger. A laptop given less than it wants charges slowly, or only holds its level while in use.
Is it safe for my phone?
Yes. The phone and charger agree a speed between them, and the phone takes only what it can use.
Should I leave a car charger plugged in?
In some cars the socket stays live with the engine off, so unplug it when you leave, and check the input if you drive a 24-volt lorry or van. The guide to fast charging covers the rest.
