The wait is finally over. From 2024, USB-C will be the common standard for electronic devices in the EU – and we have already seen the impact !
It means
- 🔌The same charger for all phones, tablets and cameras
- ⚡ Harmonised fast-charging technology
- 🔄Reduced e-waste
One charger to rule them all.
Now, a reality.

Unbundling the sale of a charger from the sale of the electronic device .
The ‘common charging’ requirements will apply to all handheld mobile phones, tablets, digital cameras, headphones, headsets, portable speakers, handheld videogame consoles, e-readers, earbuds, keyboards, mice, and portable navigation systems as of 2024. These requirements will also apply to laptops as of 2026. Such transition periods will give industry sufficient time to adapt before the entry into application.
Consumers will be able to purchase a new electronic device without a new charger. This will limit the number of chargers on the market or left unused. Reducing production and disposal of new chargers is estimated to reduce the amount of electronic waste by 980 tonnes yearly
Producers will need to provide relevant visual and written information about charging characteristics, including information on the power the device requires and whether it supports fast charging. This will help consumers understand if their existing chargers meet their new device’s requirements and/or help them select a compatible charger. Combined with the other measures, this will help consumers to limit the number of new chargers purchased and save at least €250 million a year on unnecessary charger purchases.
L’attente est finalement terminée. À partir de 2024, l’USB-C deviendra la norme commune pour les appareils électroniques dans l’UE – et nous avons déjà vu son impact !
Cela signifie
- 🔌Le même chargeur pour tous les téléphones, tablettes et appareils photo
- ⚡ Technologie de charge rapide harmonisée
- 🔄Réduction des déchets électroniques

Les exigences de « charge commune » s’appliqueront à tous les téléphones mobiles portables, tablettes, appareils photo numériques, écouteurs, casques, haut-parleurs portables, consoles de jeux vidéo portables, liseuses électroniques, écouteurs, claviers, souris et systèmes de navigation portables à partir de 2024. Ces exigences s’appliquera également aux ordinateurs portables à partir de 2026. De telles périodes de transition donneront à l’industrie suffisamment de temps pour s’adapter avant l’entrée en application.
Les consommateurs pourront acheter un nouvel appareil électronique sans nouveau chargeur. Cela limitera le nombre de chargeurs sur le marché ou inutilisés. On estime que la réduction de la production et de l’élimination des nouveaux chargeurs permettrait de réduire la quantité de déchets électroniques de 980 tonnes par an.
Les producteurs devront fournir des informations visuelles et écrites pertinentes sur les caractéristiques de charge, y compris des informations sur la puissance requise par l’appareil et s’il prend en charge une charge rapide. Cela aidera les consommateurs à comprendre si leurs chargeurs existants répondent aux exigences de leur nouvel appareil et/ou les aidera à sélectionner un chargeur compatible. Combinée aux autres mesures, cette mesure aidera les consommateurs à limiter le nombre de nouveaux chargeurs achetés et à économiser au moins 250 millions d’euros par an sur les achats inutiles de chargeurs
Since everyone here seems so confused by USB naming schemes, a short primer:
USB 3.0, 3.1, 3.2, and USB4 are the major and minor revision number of the standard. You don’t have to worry about it if you are not implementing it yourself.
The Gen number indicates the supported transfer speed, Gen 1 is 5Gbps, Gen 2 is 10, Gen 3 is 20, regardless of the spec revision.
(USB 2.0 is 480mbps)
Dual lane (Gen ?x2) means you take the speed of the Gen number and multiply it by 2.
The only major difference between USB 3 and 4 is that USB4 uses Type C plug only, whereas USB 3 can use a variety of connectors.
All USB-PD compliant cables support up to 100w of power delivery, only cables labeled as EPR (extended power range) supports up to 240w of power.
Also to add to this, the USB-C connector is perfectly compatible with the actual USB data protocol all the way back to the original USB (1.0) in low speed mode (with its mind-dazzling 1.5Mb/s speed) - all the required pins are still there as are the bits of electrical signalling necessary in the original USB protocol.
It’s just that USB-C adds more data lines and other things used in the more modern versions of the USB protocols (including for the newer power protocol - USB-PD, though maintaining backwards compatibility with the old power provision which was controlled via the USB data protocol itself) as well as support for the connector being flippable (works whatever way you plug it in) which is done by basically having the original lines appear twice, one on each side of the connector.
Isn’t there a change in how USB is represented now? They should now have the max speed and power on the cable/adapter
What the above user is saying is how it’s listed in specs and technical documents
What you are saying is how the USB IF recommends it be marketed. In theory, yours is the only one the average person should worry about these days
However in the real world it’s an absolute mess of OEMs advertising their ports as being one or the other naming schemes, or neither and just saying “USB”
Isn’t standard USB C cables only 3A (60W)? And 5A (100W) only if they identify themselves with a built in chip?
Also, USB4 can optionally support PCIe tunneling, which is a fancy way of saying it supports plugging more advanced types of hardware in (like GPUs, high-speed network cards or NVMe SSDs) at speeds of up to 40Gbps.
And there is USB4 v2 (not kidding, that’s the name) which extends USB4 to up to 80Gbps, but there are no devices that support that yet.
