    This 1-meter USB step-up cable converts common 5V USB power into constant 9V DC power, with a maximum output current of 800mA. Equipped with a universal 5.5x2.1mm DC male tip, it can easily power various low-power DC devices without a dedicated 9V power adapter.

    The internal high-efficiency step-up module maintains stable voltage transmission during long-time operation, effectively avoiding unstable power fluctuations that may damage your electronics. The flexible outer wire shell resists daily bending and abrasion for extended service life.

    Compatible with all 5V USB power sources including wall adapters, laptop USB ports and portable power banks. Widely suitable for small electrical equipment such as cooling fans, LED lights, mini routers and small speakers.

    No extra drivers or complicated setup required. Just plug the USB end into your power supply and connect the DC barrel tip to your device to start powering instantly, an economical portable power conversion cord for home and outdoor use.
