USB 5V to DC 9V Step-Up Cable

This 115cm cable converts a standard USB 5V source into a regulated DC 9V output. It replaces disposable 9V batteries in devices such as digital multimeters, microphones, remotes, toys and medical equipment. The barrel connector follows the 6F22 battery polarity with a positive male centre and negative female sleeve. It draws power from any USB port or charger.

Suits battery-free 9V devices only

Ideal for users who want to eliminate 9V battery waste on low-draw gear like testers, smoke alarms or game controllers. Not suitable for charging rechargeable 9V cells or powering equipment that demands more current than a USB 5V supply can deliver. Buyers needing higher voltage or adjustable output should look at a different converter.

Plug into any USB-A port

The cable requires a USB-A host capable of supplying the device's current draw; no external adapter is included. Its 115cm length frees placement of the 9V device away from the power source. The fixed 9V output means the connected gear must tolerate that exact voltage. Ensure the target device uses the standard 6F22 terminal layout before connecting.

Questions about this item

What USB power source do I need to run this 115 cm step-up cable?

Any USB port or charger that delivers 5 V will power the cable; it converts that input to a steady 9 V DC output.

Will the 9 V terminal connector fit the battery compartment of my 6F22 device?

Yes, the male terminal is positive and the female terminal is negative, matching the standard 9 V 6F22 battery layout.

How can I confirm the cable is delivering 9 V after I plug it in?

Measure the output with a multimeter set to DC volts; you should read 9 V at the terminals when the USB side is powered.
