This article covers chenyang 2イン1マイクロUSB OTG電源アダプター Micro USBオス→USB 2.0メス 90度左角度コネクタアダプター.

Overview

The chenyang 2-in-1 Micro USB OTG Power Adapter is a compact accessory that connects Micro USB-equipped smartphones and tablets to USB 2.0 peripherals via a 90-degree left-angle connector. Its aluminum alloy body measures just 11×11×11 cm and weighs only 20 grams, making it highly portable and ideal for tight spaces like car dashboards or crowded desks. This adapter stands out with its 90-degree left-angle design, which routes cables sideways to save space and reduce strain on the device port. It supports OTG (On-The-Go) functionality, allowing you to connect USB flash drives, mice, keyboards, and other peripherals directly to your mobile device. The 2-in-1 design also enables simultaneous power delivery, so you can charge your device while transferring data through a single adapter.

Connectivity & Compatibility

The adapter features a Micro USB male connector on the host side and a USB 2.0 female port on the device side. It supports USB 2.0 standards with data transfer speeds up to 480 Mbps. It is compatible with OTG-enabled Android smartphones and tablets, as well as some Windows tablets that use Micro USB ports. Always verify that your device supports OTG before purchasing. Setup is straightforward: plug the Micro USB male end into your device's charging/data port, then connect your USB peripheral (flash drive, mouse receiver, etc.) to the USB 2.0 female port. For power-hungry devices like external hard drives, an additional power source may be required.

Product Info

Released around fall 2023, this adapter is priced at approximately ¥3,228 on as of June 2026. The package includes only the adapter itself; warranty terms follow the manufacturer's policy, so check the product page for details. Positioned as an entry-level OTG solution, the chenyang adapter offers solid value with its aluminum alloy build and practical 90-degree connector. While it lacks the premium branding of first-party accessories, its compact design and dual functionality (data + power) make it a cost-effective choice for everyday use.

Best Use Cases

First, this adapter is perfect for drivers who use their smartphone as a GPS navigator in the car. The 90-degree left-angle connector keeps the cable neatly tucked to the side, reducing clutter on the dashboard. However, it works best when the device's Micro USB port is on the left side; right-side ports may require awkward cable routing. Second, it suits users who frequently transfer files between their smartphone and USB flash drives. With OTG support, you can quickly move photos, documents, or music without needing a computer. The small footprint means it won't take up much desk space. Third, it's ideal for tablet users who attach their device to a stand and want to connect a USB mouse or keyboard. The angled connector avoids interference with the stand, providing a stable connection. Just check your tablet's port orientation to ensure the left-angle design fits.

Things to Consider

This adapter is exclusively for Micro USB ports; it will not work with USB Type-C devices found on most modern smartphones and tablets. Additionally, OTG functionality depends on your device's hardware and software support—non-OTG devices will not recognize connected peripherals. The 90-degree left-angle design is optimized for devices with the Micro USB port on the left side. If your device's port is on the right or top, the cable may protrude awkwardly. Measure your device's port location before buying. While the adapter supports power delivery, it is not designed for high-current devices like external hard drives. Stick to low-power peripherals such as flash drives, mice, and keyboards for reliable operation.
