Most portable PCs will not need to be equipped with an ugly barrel jack and a proprietary power brick to charge. The USB Implementers Forum (USB-IF) has just announced (via CNET) that it is more than double the amount of power it sends over a USB-C cable up to 240 watts, meaning you will eventually be able to plug in You will find the same type of multipurpose USB-C cable that you currently use on lightweight laptops, tablets and phones, but to charge the best gaming laptops.
Previously, the USB-C power delivery spec tops out at 100 watts, and it certainly puts the industry back a tad – for example, while my own Dell XPS 15 can technically charge USB-C, It requires 130W of power to charge and run on full bore simultaneously.
Some manufacturers have sold off-spec USB-C adapters but they are not always bundled with machines and usually have a fixed, non- There are detachable cables.
But with 240W of power – something that USB-IF is calling “extended power range” or EPR for short – you could theoretically charge a full-fat Alienware m17 gaming laptop over USB-C.
To take advantage of the new device you will need a new USB-C charger and cable, however, you should hopefully be able to tell which one is: “All EPR cable must be clearly marked with EPR cable identification items Will be recognized, “reads part of USB-IF requirements for new imagery. A cable would need to support 5A and up to 50V to be compliant.
There will still be exceptionally fleshy laptops that certainly demand more than 240W of power. The 330W power supply still comes standard with some machines, and there are always foreign notebooks that require more than one power supply to function.
Gaming desktops generally require far more power, the latest desktop graphics card requires a 650W PSU or higher PSU, and 240W may not be sufficient for the latest game consoles from Sony and Microsoft.
On the other hand, as the years pass, some computers are becoming more efficient. Case in point: The colorful new iMac comes with a 143W power adapter. In a year or two, it will be a viable candidate for USB-C power.
