DC 5V to 9V 12V Step Up Boost Converter Power Cable 5.5x2.1mm DC Barrel Jack Voltage Boost Module Wire for Router, CCTV Camera, LED Strip, Small Fan and Low-Voltage Electronic Equipment Power Supply

This DC 5V to 9V/12V step-up boost converter power cable is a compact wired voltage lifting module designed to upgrade low-voltage 5V power sources into higher 9V or 12V working voltage, solving the problem that many small electronic devices cannot be directly powered by ordinary 5V power banks, USB adapters and computer USB ports.

It adopts a built-in high-efficiency DC-DC boost chip with stable voltage regulation performance, effectively filtering voltage ripple and avoiding equipment damage caused by unstable power supply. The terminal is equipped with a universal 5.5*2.1mm DC male barrel connector, which is the most common power interface for wireless routers, optical modems, mini cooling fans, LED light strips, small surveillance cameras, portable audio players and single-board microcontrollers.

The internal circuit adds multiple safety protection mechanisms including over-current protection, over-voltage protection, short-circuit protection and thermal shutdown protection. Once abnormal load or short circuit occurs, the module will automatically cut off output to protect both the connected load and the front-end 5V power supply.

The overall cable integrated structure eliminates the trouble of additional circuit board installation and wiring, features flexible wire body for easy layout in narrow spaces such as equipment cabinets and DIY project boxes. It is widely used in daily household power expansion, electronic hobby DIY production, temporary outdoor equipment power supply and laboratory low-power test projects. Please confirm your devices required working voltage and rated current before purchase to match the correct output version.
