USB-C is set to go from 100W to 240W, enough to power more rugged laptops – fr


Soon, the majority of laptops habit must be equipped with an ugly cylindrical jack and an exclusive power supply to charge. The USB Implementers Forum (USB-IF) has just announced (via CNET) that it is more than double the amount of power you can send through a 240-watt USB-C cable, which means you’ll eventually be able to plug in the same type of versatile USB-C cable you currently use on lightweight laptops, tablets, and phones to charge all but the most rugged gaming laptops.

Previously, the USB-C Power Delivery specification peaked at 100 watts, and that has definitely held the industry back a bit – for example, while my own Dell XPS 15 can technically charge over USB-C, it needs 130W. power to charge and run at full bore simultaneously. Some manufacturers have sold out-of-spec USB-C adapters (I have a Dell docking station that outputs 130W), but they don’t always come with machines and usually have a fixed, non-detachable cable to prevent use. abusive.

But with 240W of power – something USB-IF calls “Extended Power Range” or EPR for short – you could theoretically charge a full Alienware m17 gaming laptop via USB-C.

You’ll need new USB-C chargers and cables to take advantage of the new specification, of course, although you should hopefully be able to tell which is which: “All EPR cables will be visibly marked with items. EPR cable identification ”part of the USB-IF requirements for the new specification read. A cable will need to support up to 5A and 50V to be compliant.

Judging by the photos below, it looks like manufacturers need to change the design of their chargers as well:


There will always be exceptionally rugged laptops that demand over 240W of power, of course. 330W power supplies still come standard with some machines, and there are always exotic machines that require more than one power supply to run. Gaming desktops typically require a lot more power, with a 650W or greater power supply required for the latest desktop graphics cards, and 240W may not be enough enough for the latest game console from Sony and Microsoft.

On the other hand, some computers become more and more efficient over the years. Case in point: The new colorful iMac comes with a 143W AC adapter. In a year or two, that would be a viable candidate for USB-C power.
