Manw USB to DC 5.5x2.1mm Step Up Cable 3.3ft 800mA

SKU CH-6BPJ-0XAYN

Converts 5V USB power to 9V output via a 5.5×2.1mm DC plug with 800mA maximum current and 3.3ft cable length

  • Converts 5V USB to stable 9V output for compatible devices
  • Standard DC 5.5×2.1mm connector fits many common gadgets
  • Maximum 800mA current provides steady power delivery
  • 3ft cable length allows flexible placement and tidy wiring
  • Powers fans, LED lights, routers, speakers and similar 5-9V equipment

Purpose and Compatibility

This Manw step-up cable converts a standard 5V USB port into a 9V DC supply using a 5.5×2.1mm connector. It is designed for users who need to power 9V devices such as fans, LED lights, routers or speakers from a USB source.

Practical Benefits

The 3.3ft length allows flexible placement of connected devices without strain. A maximum current of 800mA provides steady power for compatible low-draw equipment, while the integrated voltage conversion removes the need for a separate 9V wall adapter.

Ideal Users and Limits

This cable suits anyone powering a single 5.5×2.1mm 9V device within the 800mA limit from a USB port. It is not for devices requiring higher current, different connector sizes, or voltage levels other than 9V output.

Questions about this item

Will the DC 5.5×2.1mm connector need replacing after frequent plugging?

The barrel connector is a standard 5.5×2.1 mm type rated for normal daily use; no periodic replacement is expected.

What limits continuous operation before the cable hits its ceiling?

The step-up circuit is capped at 800 mA, so sustained draw above that will trigger protection or voltage drop.

Does the cable get hot or draw extra power when running a router all day?

It converts 5 V USB input to 9 V output with minimal loss, staying cool during typical 800 mA loads.
