USB cables come in different sizes and shapes, making it tricky sometimes to identify the right cable for your device. One of the most common USB cable types is the micro USB cable, used for charging and syncing many smartphones, tablets, cameras and other gadgets. Here’s a guide on how to identify a micro USB cable and make sure you get the right one.
What is a micro USB cable?
A micro USB cable has a small, rectangular USB connector on one end that plugs into your device. The other end of the cable is a standard USB connector that plugs into a power adapter, computer or other USB port.
Micro USB cables are designed for transferring data and charging devices that support micro USB ports. This includes most Android phones and tablets, older Blackberry devices, digital cameras, external hard drives, handheld gaming systems, fitness trackers, and more.
Some key identifying features of a micro USB cable include:
- Rectangular connector approximately 6mm x 2.5mm in size
- Often used with smartphones, tablets, cameras, speakers and other portable electronics
- Supports USB 2.0 data transfer speeds
- Charges devices at up to 2.1A (amperes) power output
Identifying the Micro USB connector
Look closely at the small rectangular connector on one end of the cable. A micro USB connector is wider than it is tall and measures approximately 6mm x 2.5mm.
Count the metal pins inside the connector. A micro USB cable will have 5 small metal pins arranged in a single row inside the port. This 5-pin design is a key way to distinguish micro USB from mini USB connectors and USB-C connectors which have different numbers and arrangements of pins.
Compare with other common USB connectors
One way to identify a micro USB cable is by comparing it side-by-side to other common USB connector types. Here is a quick comparison:
| Connector Type | Shape | Size | Common Uses |
|---|---|---|---|
| Micro USB | Rectangular | 6mm x 2.5mm | Smartphones, tablets, cameras, speakers, fitness trackers |
| Mini USB | Square | 6.9mm x 3.1mm | Older digital cameras, MP3 players, peripherals |
| USB-C | Oval | 8.4mm x 2.6mm | Newer smartphones, laptops, tablets |
| USB 3.0 | Rectangular | 11.5mm x 4.5mm | Flash drives, external hard drives, peripherals |
As you can see, the micro USB connector is the smallest of these common types. It has a very distinct rectangular shape that sets it apart from the square mini USB and oval USB-C connectors. Looking at the size and number of pins is an easy way to confirm you have a micro USB cable.
Check cable labeling or icons
Many cables will have text or icon labels stamped into the plastic insulation near the USB connectors. Look for words like “Micro-B” or a micro USB icon on the cable:
On cables with labeling, there may also be indications of data transfer speeds, like “Hi-Speed USB 2.0”, or power ratings like “5V/1A” printed on the cable. Checking these ratings can provide additional confirmation you have a micro USB cable.
Try connecting to a micro USB device
To be absolutely certain your cable is micro USB, go ahead and try using it! Locate a device you know has a micro USB port like a smartphone or digital camera. Insert the suspected micro USB cable and see if it fits and functions properly. If it connects and works as expected, you can confirm that you have a micro USB cable.
Where to use a micro USB cable
Micro USB cables are designed to work with portable electronics like these:
- Android smartphones and tablets
- Blackberry devices
- Digital cameras
- Bluetooth speakers and headphones
- Handheld gaming systems
- eReaders like Kindle
- Portable chargers and power banks
- Fitness trackers and smartwatches
- GPS devices
- External hard drives and flash drives
You’ll want to use a micro USB cable to charge and sync your device using a USB charging port or data connection on a computer. However, avoid plugging micro USB cables into non-compatible ports like USB-C, or you may damage your device.
Pro tips for using micro USB cables
Here are some useful tips for working with micro USB cables:
- Insert the cable gently and correctly oriented – don’t force it if it doesn’t fit.
- Unplug the cable by pulling the connector, not the cord.
- Avoid wrapping cables too tightly or bending them at sharp angles.
- Inspect cables periodically for damaged, frayed or broken connectors.
- Replace cables that have become worn or damaged.
- Use cables rated for your device’s charging speed to avoid issues.
Conclusion
Identifying a micro USB cable is easy once you know what to look for. Examine the small, rectangular connector, count the five internal pins, and compare to other USB cable types. Check any text labeling for confirmation, or test the cable with a compatible device. With this guide, you can find the right micro USB cable for all your devices.
Making sure you have the right cable for your smartphone, tablet, camera or other gadget saves you from charging or connectivity issues. Follow these tips for recognizing micro USB cables in the future.
