January 1, 2025, is the date for mobile phones and other small electronic devices. Saudi Arabia announced a law to standardize charging ports for all...
There is a second stage, starting from April 1, 2026, which will apply to laptops and portable computers.
I’m with them on small devices using USB C, but all laptops is a pretty tall task. Can gaming laptops that need a high voltage even use USB-C? They already struggle with massive charging bricks and thick cables.
The latest USB power delivery standard allows for new voltages of 28, 36, and 48 volts at up to 240 watts at 48V. My current Dell workstation laptop uses two 20V USB C connectors to achieve similar.
I’m imaginining some kind of monstrosity of a gaming laptop with a power cable that looks like a hydra splitting into three or four USB-C connectors, and it’s gloriously silly.
Maybe it’s time for a new thing similar to USB 3.0 micro B, with two USB-C connectors next to each other on the same plug.
It would make since to say something like usb-c is required for up to x volts. Then x-y volts require this other kind of charger.
I mean it’s totally valid if the required technology literally can’t handle certain applications that there needs to a level 2, level 3, and onward option.
I’m chuckling at the idea of someone plugging in an early USB-C device and watching it go up in flames as it gets hit with 48v instead of the 5v that it’s rated for. I know USB-C has a chip that is supposed to negotiate power transfer, but it’s still a funny “what if” thought.
Lol where is this “chip” because between the all the cables, chargers, and devices bought off Alibaba or Aliexpress Amazon that’s bound to happen at some point.
It’s built into the connector. The connector isn’t just wires soldered to contacts; It’s a PCB with actual circuitry. When you plug a device in, it uses that chip to tell the charger how much power to send. Then the charger receives that signal, and sends the appropriate amount of power.
If the signal isn’t received, then the charger should only send the bare minimum amount that any device should be able to handle, for things like flash drives or peripherals. This is why some of the cheaper cables won’t charge your newer devices, because those newer devices need more power and the old cable isn’t negotiating a high enough power transfer.
It’s ironically one of the biggest complaints that people have about USB-C, because it causes a nightmare in regards to compatibility. Old cables and chargers are constantly being phased out as the standard gets developed for more and more power transfer. And that outdated equipment is still sitting on shelves, waiting to be bought. A cable or charger that you bought a month ago may not be compatible to charge a device that you buy today, because that unit is actually a year old and was phased out six months after it was manufactured and shipped, but has been on a store shelf ever since because a retailer bought a bunch and doesn’t want to write them off as a loss.
It means people are constantly re-buying the same gear at higher specs, simply to keep up-to-date with existing standards. And if you don’t re-buy everything then you have a hodgepodge mix of cables and chargers that all look the same and only some of them will charge all of your newer devices. The older stuff looks the same on the outside, but your new phone will refuse to charge when you try to use them.
That’s not really true. The E-Marker in the cable does not do the negotiations. Its involved in it but its not as complicated as you make it sound. There are a total of 3 different completely backwards compatible cable types in regards to power delivery. 60W , 100W (which is legacy) and 240W.
I recently bought a gaming laptop. Specifically a Lenovo Legion 5 with a rx 6600. It has both the big powerbrick charger and can be charged via USB-PD, obv not at the same speed but it is an option that is available.
I specifically buy cables with different colors or from different brands as I upgrade, and keep a note around for what their PD capacity is for each set. It’s annoying, but doable.
the ASUS ROG STRIX SCAR 17, their biggest baddest gamiest 17" laptop, ships with a power adapter rated for 280W. it also offers charging over USB-PD at up to 240W, so would comply with the regulation here.

Pretty much, they magnet together though so you can split them apart and use them as normal with other devices.

Ah… so that explains why I have two dozen USB-C cables and only like 5 of them will fast charge my phone.

Not gaming (obviously!) but the2019 MacBook Pro has a 140W USB-C charger to a single port.
2019 is 96w charger. 140w is 2021 or later.
Probably. But your will have to buy the correct charger and cable. I have a couple 100W cables. The problem is they Al look alike.
The label maker business is about to be booming!

your gaming laptop is struggling because gaming laptops are scams. you’ll never get the performance you want and you’ll pay the premium anyways.

i think some companies use seperate ports for charging and gaming on gaming laptops
