This USB step-up converter upgrades common 5V USB power to stable 9V or 12V adjustable DC power, fitted with a 3.5x1.35mm barrel connector to power various low-voltage small appliances without dedicated matching chargers.
The integrated digital LED display intuitively shows real-time voltage and current data, allowing you to check operating status at a glance. Adopting high-efficiency boost chip, the module minimizes power loss and heat accumulation, maintaining steady output voltage even under sustained load to avoid device shutdown or damage caused by unstable power.
Multiple built-in safety protections against overcurrent, overvoltage, short circuit and overheating automatically cut off output once abnormal conditions occur, fully protecting your connected equipment. Mini lightweight body takes little storage space, easy to carry for indoor use, outdoor shooting and travel.
Simply insert the USB end into any 5V power source and connect the DC tip to your target device to start power supply instantly. It is a practical multi-scene power conversion accessory to replace multiple single-specification chargers.
