Tips

Before connecting, verify that your device requires 5V and draws no more than 4A. The barrel plug must match the size and polarity of your device's input—center positive is the most common, but always double-check. For devices with different connector sizes, use a suitable adapter tip. Keep the adapter in a well-ventilated area and avoid covering it during operation.
