USB 2.0 step-up cable for 12 V devices

This 0.3 m cable converts a USB 2.0 Type-A 5 V source into a 12 V DC 5.5 × 2.1 mm male output. It is intended for users who need to power small 12 V equipment from a standard USB port or power bank. The male-to-male design plugs directly into the host and the device without extra adapters.

Handles 12 V loads up to 800 mA

The built-in boost circuit accepts a maximum 5 V 2 A input and delivers up to 12 V at 800 mA. It will run compatible routers, mini monitors, speakers, fans and similar gear within that envelope. Devices drawing more current or requiring a different voltage will not operate reliably.

Limited to USB 2.0 power delivery

The cable uses the USB 2.0 interface, so input current is constrained by the host port or charger capability. It provides no data path — only two-core power conductors — and cannot support devices that need higher wattage or a different connector polarity.

Questions about this item

Will the 0.3 m step-up cable let me run a 12 V router from an older 5 V 2 A USB power bank?

Yes, the cable accepts 5 V 2 A input and delivers 12 V at up to 800 mA through the 5.5 × 2.1 mm plug, matching many legacy routers.

How do I confirm the boost converter is active once I plug it in?

The built-in indicator light illuminates when the cable is powered and the protection IC is functioning.

Does the package include a USB power source or only the 180° angled cable itself?

Only the 0.3 m USB-A to DC5521 step-up cable is supplied; a 5 V USB charger or power bank must be provided separately.
