USB step-up adapter for 9V and 12V devices

This adapter converts a standard 5V USB source into selectable 9V or 12V DC output. It delivers up to 1A at 9V or 0.8A at 12V through a 3.5mm x 1.35mm barrel connector. An integrated LED display shows the active output voltage. The 0.8 metre cable allows flexible placement for routers, fans or audio gear.

Suits low-power gear needing 9V or 12V from USB

Ideal for powering a router, Bluetooth speaker or small fan from a power bank during outages. Not suited for devices drawing more than 1A at 9V or 0.8A at 12V. Buyers needing higher current, adjustable voltage beyond the two fixed steps, or a different connector size should look elsewhere.

Dual-voltage selector with LED readout

A physical switch toggles between the two fixed output levels, and the onboard LED display confirms the selected voltage in real time. This single feature determines whether the adapter matches the target device’s input requirement.

Questions about this item

How do I confirm the adapter is supplying the voltage I selected?

The built-in LED display shows the active output voltage, either 9 V or 12 V, after you flip the switch.
