Older portable speakers, GPS units, and media players usually charge and connect over one of two similar-looking but incompatible connectors: Micro-USB or Mini-USB. Buy the wrong one and it simply won't fit. Here's how to tell them apart, and which of our cables fits which.
Micro-USB vs Mini-USB: the quick way to tell them apart
Both are small, flat USB connectors found on older or budget electronics — but they're physically different shapes:
- Micro-USB has a thin, trapezoid-shaped port — this became the standard charging port on most Android phones, budget electronics, and portable speakers roughly 2010 onward.
- Mini-USB is slightly larger and more rectangular with two shallow notches on the sides — common on older digital cameras, MP3 players, GPS units, and pre-2012 electronics.
The safest way to be sure: look at the port on your actual device, or check the connector on the charging cable it originally came with — that will match one of the two below.
Got a Micro-USB device that also needs AUX audio out?
Our 2-in-1 Micro-USB Charging & 3.5mm AUX Audio Adapter Cable, S$2.99, powers your device over Micro-USB while sending audio out over a 3.5mm AUX jack — useful for portable speakers or older phones that need to stay charged while playing through a car stereo or amplifier.
Got a Mini-USB device instead?
Our 3-in-1 AUX Audio & Power Cable (USB-A to Mini-USB & 3.5mm Jack), S$5.99, does the same job for older Mini-USB devices — legacy media players, older cameras, and similar hardware that predates Micro-USB.
Different problem: your external hard drive keeps disconnecting
If what you're actually dealing with is a 2.5-inch external hard drive or SSD enclosure that clicks, disconnects, or fails to be recognised — that's usually not an audio problem at all. It's a power problem: a single USB port often can't supply enough current for the drive to run reliably.
Our USB 3.0 Dual Power Y-Cable (Micro-B), S$5.99, draws supplemental power from a second USB port to keep high-draw drives stable — no audio involved, just a stable connection for your data.

| External hard drive disconnecting/clicking | USB 3.0 Dual Power Y-Cable | S$5.99 |
Frequently Asked Questions
How do I know if my device is Micro-USB or Mini-USB?
Check the port shape: Micro-USB is thin and trapezoid-shaped; Mini-USB is a bit wider with two side notches. If you still have the original charging cable, its connector will match one of the two exactly.
Can I use these cables for data transfer too?
No — the 2-in-1 and 3-in-1 AUX cables are for charging and audio only, not data. If you need to transfer files, you'll need a standard data-capable USB cable for your connector type.
Will the dual-power Y-cable definitely fix my hard drive's disconnecting issue?
In most cases, yes, if the cause is insufficient power from a single USB port — which is the most common reason. If your drive still disconnects after using it, the drive or enclosure itself may have a separate fault.
Do these cables work with USB-C devices?
No — these are specifically for Micro-USB and Mini-USB connectors. If your device uses USB-C, check our USB Hubs and Adapters collection for USB-C compatible options.
