USB Cable
USB-A to Micro-USB Cable
USB-A to Micro-USB cables were widely used for phones, controllers, cameras, storage devices, and accessories before USB-C became common.
Characteristics
| Connector ends | USB-A to Micro-USB, most commonly Micro-B |
|---|---|
| Reversible | No |
| Typical uses | Older Android phones, game controllers, cameras, portable electronics, accessories, and external storage |
| Common data support | USB 2.0 is common with standard Micro-B |
| SuperSpeed variant | Wider SuperSpeed Micro-B cables and receptacles add contacts for USB 3.x operation and are physically distinct from standard Micro-B |
| Charging | Widely used for legacy USB charging and device power |
| OTG role | OTG behavior depends on the Micro-USB connector form and device implementation; a normal USB-A to Micro-B cable does not by itself make a device a host |
| Main compatibility rule | Identify whether the device uses standard Micro-B or the wider SuperSpeed Micro-B form before choosing a cable |
