USB to DC Step-Up Adapter

This compact adapter converts a standard USB 5V source into stable 9V or 12V DC power through a 5.5x2.1mm male plug. It suits owners of routers, CCTV cameras, LED strips, single-board computers and other low-power 9V or 12V devices who want to run them from power banks, laptop ports or USB chargers. The integrated cable design removes the need for a separate bulky module and simplifies wiring in tight spaces.

Replaces Bulky External Power Bricks

The unit upgrades an existing 5V USB supply so you can retire the original wall wart that came with a 9V or 12V device. The jump is worthwhile when you need portable or UPS-backed operation for a router or camera, or when a single USB hub must feed several low-voltage gadgets. It is not for equipment that draws more current than the USB host can deliver, nor for appliances requiring voltages other than 9V or 12V.

Plug-and-Play Installation

Connect the USB end to any 5V port and the DC plug into the device; no drivers or configuration are required. The built-in boost chip maintains steady output with low ripple, and the flexible jacket resists repeated bending. Problems usually arise only if the USB source cannot supply sufficient current for the connected load, causing voltage sag or intermittent operation.
