What this cable does

A USB 2.0 male to DC 5.5×2.1mm boost cable steps 5 V input up to 12 V output. It lets you power 12 V devices such as routers, cameras or mini speakers from a standard USB‑A port or power bank. The 1 m length gives flexibility for desk or travel use.

Build and daily use

Oxygen‑free copper conductors reduce resistance and resist corrosion over time. An integrated protection IC guards against over‑voltage, over‑current, overload and short‑circuit conditions. A built‑in switch and indicator light show when the converter is active.

Power limits to know

The adapter is rated for a maximum 5 V 2 A input and 12 V 800 mA output. Devices drawing more current than 800 mA at 12 V will not operate reliably. Check your equipment’s power label before connecting.
