USB 5V to 12V Step Up Boost Converter Cable, USB Power Bank to 12V DC Power Supply Cord, Voltage Boost Cable for WiFi Router, Modem, Cooling Fan, Speaker, Portable Devices Emergency Backup Power

This USB 5V to 12V step-up boost cable is a handy voltage conversion cord designed for emergency power supply. It accepts standard 5V power output from USB ports or power banks and elevates the voltage to steady 12V DC, allowing you to operate your 12V small devices without plugging into wall sockets.

The internal high-efficiency boost module delivers reliable voltage conversion. Equipped with multiple circuit protection mechanisms including over-current protection, short-circuit protection and over-temperature protection, which greatly lower potential risks to connected devices.

It is widely applicable to WiFi routers, network modems, cooling fans, portable speakers and more 12V low-consumption gadgets. During power failures or outdoor activities, you can simply use a power bank to maintain your network or power small appliances.

The all-in-one cable design saves space and is easy to carry. No complicated installation or drivers required, ready to use right after connection.

Important Notice: Please confirm your device requires 12V working voltage and its power consumption is within the cables load range. This cable only supports 5V to 12V boost conversion and cannot be used reversely for voltage step-down.
