15 cm 5.5×2.1 mm barrel-to-Mini-USB adapter

This short cable converts a 5.5×2.1 mm DC barrel output into a Mini-USB-B plug so a standard power adapter can charge or run Mini-USB devices. The 15 cm length keeps cable clutter low in tight camera rigs or embedded projects. It is built for installers who need a quick gender-and-type change without soldering.

Sustained-load behaviour

The 0.3 mm² conductors and 3.5 mm outer diameter are sized for the modest currents typical of USB charging, not for high-wattage DC distribution. Voltage drop stays negligible over the 15 cm run at normal USB current levels. The moulded strain relief on each end resists fatigue from repeated connect-disconnect cycles.

Practical limits of the barrel-to-USB interface

Polarity follows the centre-positive convention common on 5.5×2.1 mm jacks; reversing the source will not damage the cable but will leave the USB device unpowered. The Mini-USB-B plug fits legacy cameras, GPS units and older portable gear; it will not mate with Micro-USB or USB-C ports. No data lines are connected, so the cable cannot be used for sync or firmware updates.

Questions about this item

Will the 15 cm cable add noticeable resistance or heat when powering a device all day?

The 15 cm length with 0.3 mm² cross-section keeps voltage drop minimal, so the cord stays cool during continuous use.

What must I already own to use this 5.5×2.1 mm barrel-to-Mini-USB adapter?

You need a power supply with a 5.5×2.1 mm male barrel plug and a device that charges via a Mini-USB port.

Can I keep using my older 5.5×2.1 mm barrel power supply with a legacy Mini-USB device?

Yes, the female barrel jack accepts the older supply and the Mini-USB male plug fits the legacy device directly.
