Universal charger: a new push from Europe

To date we have two counterparts on the types of charger connectors: Android manufacturers who use USB-C largely (and old smartphones with micro USB-B) and Apple with its Lighthning connector . However, Europe is once again pushing towards the use of a USB-C connector for everyone, including Apple.

During the early 2000s, each manufacturer had its own proprietary charger with a unique connector and certainly not usable on other models of mobile phones. With the advent of smartphones, the various manufacturers have begun to move (also thanks to the push of some organizations) towards a single standard, with the exception of Apple which has remained the owner .

The aim is therefore to adopt a single and shared standard for all types of mobile devices, primarily smartphones and tablets. A new Commission proposal on the subject is expected on 23 September .

The advantages of using universal chargers

The advantages of using universal chargers are manifold. First of all, we look at the perspective of reducing electronic waste . In fact, by switching from one smartphone to another, it is possible to reuse old chargers that should no longer be necessarily thrown away (except for operational problems), and companies could start to stop selling new chargers, giving consumers the possibility to choose whether to use their old chargers. or less.

USB-C is already a shared standard in the mobile device landscape. All major smartphone manufacturers in the world have already made use of this technology . Even Apple, while still stopping at the proprietary lighthing port for most of its devices, has begun using a USB-C input for devices such as the iPad Mini 2021.

Apple is obviously reluctant to completely abandon its connector. Even iPhone 13 has a lightining entrance, and the position of the Cupertino group on the issue is clear: an obligation of this type would entail putting a brake on innovation, affecting consumers in a negative way.

Not only wired charging but also wireless

Obviously , the Wireless Qi charging mode cannot be ignored in any way. Now all manufacturers, from Android to Apple, support wireless charging based on Qi technology.

It is therefore an example of a single standard, which allows you to take advantage of various brands' bases to power the smartphone, albeit with longer times than the wired mode due to the significant reduction in efficiency of the system based on the phenomenon of magnetic induction .

A few details on USB-C

usb-c

USB-C is a standard of USB connectors and cables (version 3.1, 3.0 and 2.0) for data and power transmission that replaces the Type-A and Type-B standards previously used on Android smartphones. Note how it is a standard on the connector and not on the technology behind it . In fact, it thinks that the USB-C standard corresponds with version 3.1 (with its maximum transfer speed of 10 Gb / s), while the Type-C connectors and cables can also support version 2.0 (therefore with maximum speed of 480 Mb / s).

Compared to other formats of connectors and USB ports, the greatest advantage of type C is certainly that of being symmetrical and therefore not having a mandatory physical connection direction , thus facilitating the connection operation.
