5V to 12V Step-Up USB-C Cable for Portable Devices

This cable converts a standard 5V USB-C power source into a 12V 8W output using an integrated step-up module. It targets users who need to run 12V equipment such as fans, table lamps, wireless routers or speakers from a 5V 2A power bank while travelling or working outdoors. The 4×1.7mm barrel connector fits compatible device inputs directly. The 115cm length gives flexibility for placement away from the power source.

Integrated Converter Module

The built-in step-up circuit replaces a separate wall adapter, letting a single power bank supply 12V gear. Intelligent protection guards against over-current, over-voltage, over-load and short-circuit events. The 4×1.7mm plug is permanently attached, so the cable only works with devices that accept that specific barrel size. No additional tips or software are included in the package.

Plug-and-Play Installation with Polarity Checks

Connect the USB-C end to a 5V 2A-capable power bank, then insert the 4×1.7mm plug into the target device. Installation fails if the power bank cannot deliver the required 2A current or if the device centre-pin polarity does not match the cable. The fixed 115cm length cannot be shortened, and the connector cannot be swapped for other barrel sizes.

Questions about this item

How often should the 4x1.7 mm plug be checked or replaced?

The plug is a standard barrel connector with no moving parts; inspect it only if the cable shows physical damage or intermittent power.

What limits continuous operation of the 12 V 8 W output?

The built-in step-up module is rated for 8 W total; sustained loads above that will activate the over-current protection.

Does the converter get hot or draw more power when run all day from a 5 V 2 A bank?

It delivers up to 12 V at 8 W with built-in overload and short-circuit protection; normal warmth is expected but no fan or active cooling is present.
