Overview

The chenyang Micro USB to USB-A OTG Host Adapter 90 Degree Right Angle with Power Port is a compact adapter that lets you connect standard USB-A peripherals to Android smartphones and tablets equipped with a micro USB port. Its 90-degree right-angle design helps keep cable routing tidy in tight spaces, and the integrated external power input ensures stable operation even with power-hungry devices like external hard drives or USB hubs. Supporting USB 2.0 (up to 480 Mbps), this adapter uses a durable metallic shell and weighs only about 10 grams, making it a practical companion for on-the-go use. The included micro USB power port allows you to supply 5V power via a separate USB power adapter, greatly expanding the range of compatible peripherals.

Connectivity & Compatibility

Connector: Micro USB male to USB-A female Compatible devices: Any micro USB-equipped Android phone, tablet, e-reader, or digital camera that supports USB OTG (On-The-Go) host mode. External power input: A dedicated micro USB power port (requires a standard USB power adapter) provides up to 5V input. Low-power devices such as a mouse, keyboard, or basic USB flash drive often work without external power, but high-power peripherals (portable HDD, USB hub, LED accessories) will need it for reliable operation. Data transfer: Limited to USB 2.0 speeds (480 Mbps). USB 3.0 or faster devices will be bottlenecked. * OTG requirement: The host device must explicitly support USB OTG. Many Android devices do, but newer models increasingly use USB-C, so check your device’s compatibility before purchase.

Product Info

Released in the second half of 2023, the chenyang adapter is primarily sold through at a typical price of around ¥3,228 (as of June 2026). The package contains only the adapter itself; no USB power adapter or cable is included. Warranty is not explicitly stated, but ’s return policy applies. This is an entry-level OTG adapter with a niche feature set: the right-angle form factor and the external power port. Few competitors offer both at this price point. Comparable straight adapters (with or without power) are available for slightly less, but lack the space-saving bend. The metallic finish gives it a durable feel that justifies the small premium.

Best Use Cases

In-car setups: Connect a USB flash drive or game controller to your phone while keeping cables neat inside the center console. External power helps maintain a stable connection even when the car’s USB port is underpowered. However, you’ll need a separate 5V/1A+ power source. Tablet desktop mode: Use a keyboard and mouse simultaneously with a tablet. By plugging an external power source into the adapter, you can also run a powered USB hub for additional ports. This works best on older Android tablets that still use micro USB, but requires the tablet to support OTG and have enough processing power for peripherals. Repurposing old Android devices: Turn an older smartphone into a media player or file server by attaching a USB SSD. Data transfer will be limited to USB 2.0, so copying large video libraries may feel slow, but for occasional access it’s perfectly adequate. Who should skip this: Users with USB-C-only devices (most modern smartphones/tablets) should look for a USB-C OTG adapter instead. Anyone needing fast file transfers (USB 3.0+) will be frustrated by the USB 2.0 bottleneck.
