Charging Cables

Introduction

The 3 most common types of charging cables for mobile devices today are Micro-USB, USB-C and Lightning.

Different Types of Charging Cables

The aim of mandatory USB-C policy is to reduce waste and make it easier for consumers to use the same charge for different devices.

    • Apple has argued that this rule would stifle innovation and harm consumers, but newer Apple product, such as MacBook Air, iPad and iPhone 15, have already migrated to USB-C.



    Micro-USB

    Micro-USB is an older type of connector that can be found on most Android phones released prior to 2015.

    • It offers a transfer speed of 480 Mbps and a maximum current of 1.8A.

    While micro-USB is still present in some budget Android devices and older models, its presence is rapidly diminishing.



    Lightning

    On the other hand, Lightning is a proprietary connector used by iPhones and other Apple devices since September 2012.

    • It offers a transfer speed of 480 Mbps and a maximum current of 2.4A.
    • To use fast charging, a USB-C to lightning cable and a 20W or higher power adaptor are required.

    To avoid malfunctions with Apple devices, it is crucial to use MFi-certified Lightning cables.

    USB Type C

    USB type C is a newer type of connector that is used by most mid- to high-level Android smartphones and latest iPhone 15.

    • It supports faster data transmission than Lightning, with
      • USB 3.1 up to 10 Gbps.
      • USB 3.2 up to 20 Gbps.
      • USB 4 up to 40 Gbps.
    • It also has a native power support for 100W/3A and up to 240W/5A; Hence, it can charge devices quickly, including laptops.

    Despite the abundance of "quick charging" technologies from various Android manufacturers, limited compatibility due to conflicting standards pose a significant challenge.

    • To illustrate, a Samsung phone using USB Type C may not benefit from Xiaomi 120 W hypercharge.



    Summary

    Wireless charging, particularly with MagSafe, holds immense promise for convenience and ease of use.

    • However, the limitations of its fast charging capabilities are a significant hurdle hindering its broader adoption and appeal.
