USB 5V to 12V boost cable for portable power

This 118 cm cable converts a standard USB 5 V source into a 12 V 5.5×2.1 mm barrel output. It lets you run a router, LED strip or similar 12 V device from a power bank during an outage or on the move. The inline converter handles up to 2 A input current.

8 W maximum output power

The boost circuit is rated for 8 W total output, so the connected device must draw less than this limit. Exceeding 8 W will trigger the built-in over-current, over-voltage and short-circuit protection and shut the cable down. Check your device’s power rating before use.

No retail packaging included

The package contains only the single black converter cable; no additional adapters, mounting hardware or documentation are supplied. You receive exactly one ready-to-use cable for immediate connection.

Questions about this item

What does the 8 W output limit mean for the 12 V devices I can run?

The boost cable delivers up to 8 W at 12 V, so it can power routers, LED strips or small 12 V appliances rated below that figure.

How does the USB input restrict what the cable can actually supply?

The USB male plug draws a maximum of 2 A at 5 V, which caps the total energy available for conversion to 12 V.

Will the 5.5 × 2.1 mm plug fit my equipment and how long is the lead?

The centre-positive 5.5 mm barrel with a 2.1 mm pin matches the common 12 V DC jack, and the cable runs 118 cm end to end.
