3. Setup
Follow these steps to set up your PERFEIDY AC Adapter:
- Identify Device Requirements: Before connecting, determine the voltage (V), amperage (A), and polarity (center positive or center negative) required by your electronic device. This information is usually found on the device itself, its original power adapter, or in its user manual. This adapter provides 5V DC output.
- Select the Correct DC Jack: Choose one of the 10 interchangeable DC jacks that matches the physical connector size of your device. Ensure a snug fit to prevent loose connections.

Figure 3.1: Visual guide for selecting the appropriate DC jack from the provided set to match your device's input port. Ensure the physical dimensions and type (e.g., Type C, Micro USB) are correct.
- Check Polarity: Verify the polarity of your device. The PERFEIDY adapter is designed for Center Positive (+) / Outer Negative (-) polarity. If your device requires a different polarity, this adapter is not suitable.

Figure 3.2: Diagram illustrating how to check the polarity of your device and confirming that the adapter supports Center Positive (+) and Outer Negative (-) configuration. This is crucial for preventing damage.
- Attach the Selected Jack: Firmly connect the chosen DC jack to the adapter's main output cable. Ensure it clicks securely into place.
- Connect to Device: Plug the attached DC jack into your electronic device's power input port.
- Connect to Power Outlet: Plug the AC adapter into a standard 100-240V AC wall outlet.
- Verify Operation: Confirm that your device powers on and functions correctly.
Important: Always ensure the voltage, amperage, and polarity match your device's requirements. Using an incorrect adapter can damage your device.
