USB-C ready to transition from 100 W to 240 W, enough to charge more robust laptops

Soon, most portable PCs will not need to be equipped with an “ugly” power charger provided by the device’s brand. Is that the USB Implementers Forum (USB-IF) has just announced that it is more than doubling the amount of energy – from 100 Watts to 240 Watts – capable of being carried by a USB-C cable, which means that it will eventually be it is possible to connect with the same type of multifunctional USB-C cable currently used in laptops, tablets and mobile phones to charge all laptops, except for the most powerful gaming notebooks.

Previously, USB-C Power Delivery supported 100 watts, and this definitely slowed the industry down a bit – for example, while a Dell XPS 15 can technically charge via USB-C, it needs 130 W of power to charge and run on your maximum capacity simultaneously. Some manufacturers have sold USB-C adapters without a specification, but they don’t actually always come with the machines and usually have a fixed, inseparable cable to prevent misuse.

But with 240 W of power – something USB-IF is calling the “Extended Power Range” or EPR – in short – it would theoretically be able to power a rugged Alienware m17 gaming laptop with USB-C.

New USB-C chargers and cables will be needed to take advantage of this new specification. Of course, you need to know how to identify and differentiate EPR cables: “All EPR cables must be visibly identified with EPR cable identification items”, says part of the USB-IF requirements for the new specification. A cable will need to support up to 5A and 50V to be compatible.

USB C ready to transition from 100 W to 240 W

Undoubtedly, there will still be particularly robust laptops that demand more than 240 W of power. 330 W power supplies still remain standard on some machines, and there are always outstanding laptops that require more than one power supply to function. Fire desktops often require a lot more power, with a 650 W PSU, and 240 W will not be enough for the latest game consoles from Sony and Microsoft.

On the other hand, some computers are becoming more efficient over the years. Embossed case: iMac’s new color comes with a 143 w power adapter. In a year or two. would be a viable candidate for USB-C power.
