Power adapter conversion

This cable converts a 4.0x1.7mm barrel power supply into a Mini USB male plug for charging compatible devices. It measures 11cm including connectors with a 3.5mm wire diameter. The pack contains two cables for immediate use. Ideal for repurposing spare barrel adapters into USB power sources.

Connector compatibility

The critical specification is the 4.0x1.7mm female barrel jack paired with a USB Mini-B male connector. Verify your power supply tip and device port match these exact dimensions before purchasing. Mismatched sizes will prevent a secure connection or power delivery. Nominal cross section is 0.3 mm square.

Suitable for legacy USB Mini devices

This suits owners of older cameras, GPS units or hard drives that charge via Mini USB and have a matching barrel adapter available. It is not for devices requiring Micro USB, USB-C or Lightning connections. Buyers needing longer reach or a different barrel size should look elsewhere.

Questions about this item

How much length does the 11 cm cord add between my barrel power supply and a Mini-USB device?

The cable measures 11 cm including both plugs, giving roughly 4.33 inches of reach between the 4.0×1.7 mm barrel jack and the Mini-USB male connector.

What does the 4.0×1.7 mm barrel jack limit in real use?

The jack only fits power supplies with a matching 4.0 mm outer and 1.7 mm inner diameter, so it caps compatibility to adapters using that exact barrel size.

Will the 3.5 mm wire diameter let this cord pass through a standard camera housing grommet?

The cord’s maximum outside diameter is 3.5 mm (0.14 inches), so it fits through any opening larger than that, such as typical camera grommets.
