USB 2.0 boost cable for 12 V devices

This 30 cm cable converts a USB 2.0 male port into a 90° DC 3.5×1.35 mm male plug, stepping 5 V input up to 12 V output. It suits routers, desk lamps, mini fans, Bluetooth speakers and similar small electronics that draw power from a USB adapter or power bank. The two-core design handles charging only and cannot carry data.

Sustained load behaviour

The cable is rated for a maximum input current of 2 A and a maximum output of 0.8 A at 12 V, giving a 10 W ceiling. Under continuous use the oxygen-free copper conductors keep resistance low and heat transfer minimal, while the indicator light confirms active operation. Exceeding the stated current or voltage limits will cause the connected device to stop working.

USB 2.0 power-delivery limits

A standard USB 2.0 port supplies 5 V, so the built-in boost circuitry is essential to reach 12 V for the barrel jack. The 10 W maximum means the cable cannot run higher-wattage equipment, and the fixed 3.5×1.35 mm plug fits only devices with that exact jack size. Users must verify their equipment matches both the voltage and the connector before purchase.

Questions about this item

How much heat does the 30 cm cable generate when running at the 10 W maximum power all day?

The cable uses 22 AWG oxygen-free copper and is described as having low heat transfer, so it stays cool during continuous operation at up to 10 W.

What power source must I already own to use this boost cable with a 12 V router?

You need a USB 2.0 port or adapter that can supply 5 V at 2 A to deliver the full 12 V 0.8 A output.

Will the 90° DC 3.5×1.35 mm plug fit the power jack on my older 9 V desk lamp?

The cable outputs a fixed 12 V, so it is not suitable for a 9 V device; check that your lamp accepts 12 V before connecting.
