The now-outdated connector frequently used to power and charge Android devices was called the Micro-USB charger. It featured a small, trapezoidal shape and was a ubiquitous standard for numerous electronic devices, including smartphones, tablets, and various peripherals, prior to the widespread adoption of newer connector types. For example, many older Samsung, HTC, and LG phones relied on this port for both charging and data transfer.
Its importance stemmed from its near-universal compatibility across a broad range of Android devices, leading to reduced electronic waste and simplified charging solutions for consumers. The prevalence of this connector also fostered a mature ecosystem of accessories, such as charging cables, car chargers, and battery packs. However, it suffered from durability issues related to its relatively fragile design and its orientation-specific insertion, requiring users to align the connector properly.
