No more laptop chargers and their proprietary connectors. USB-C certification evolves to homologate going from 100 to 240 watts of maximum power via the USB socket standard being deployed.

[EN VIDÉO] In 2050, we will be working with transparent computers Today we are glued to our screens, but tomorrow, augmented reality and the power of computers will free us from our workstations, thanks to transparent or virtual screens. This is what Planète + explains to us in its new episode of Dreaming the Future, broadcast this Friday, February 3, 2017, and of which here is an exclusive extract.
Here is a revolution in the revolution ofUSB. The last standard USB-C which is being rolled out gradually, both on mobile devices and on computers, whether they are PCs or Mac, will remove the ugly power plugs proprietary to laptops. To go further, the USB Developers Forum (USB-IF) comes to announce that the standard be changed to “revision 2.1”. A revision which certifies that it is possible to go beyond twice the current power in watt that this connection can accept.
While she capped at 100 Watts, which was already enough to power most of the computers portable, it now peaks at 240 Watts. With such power, it is now possible to power the vast majority of desktops and laptops for gamers.
Cables of 5 A and 50 V minimum
Being able to use theUSB-C beyond its previous specifications was already known and non-standard adapters were even marketed to achieve this. This did not pose any particular problems since indeed, it is possible from the start to push this power to 240 Watts. The new specification was dubbed “Extended Power Range” (EPR). It is precisely this label that will be affixed to cables and compatible chargers.
To be part of this category, a cable will have to support up to 5 A and 50 V. So, obviously, for machines requiring more power, the standard will not suffice and there will always be power supplies going beyond, with their proprietary cables.
