2. Informazioni sulla sicurezza
Osservare le seguenti precauzioni di sicurezza per evitare lesioni o danni al dispositivo e alle apparecchiature collegate:
- Nota importante: This product is an AC to DC adapter, not a charger. It cannot be used to charge electronic devices with batteries.
- Verificare sempre il volume correttotage and current requirements of your device before connecting. Incorrect voltagpuò danneggiare la tua attrezzatura.
- Garantire il volume di lavorotage of your device is DC 4V~24V and the current is not greater than 6A.
- For optimal performance and longevity, it is recommended to use the adapter at less than 80% of its full load capacity (i.e., less than 115.2W).
- The adapter features built-in safety protection systems including automatic over-voltage cut-off, over-current cut-off, over-temperature cut-off, and short-circuit cut-off.
- The exterior is made of fire-retardant material to minimize fire hazards.
- Use only indoors. Keep the adapter away from water, moisture, and high temperatures.
- Do not disassemble or modify the adapter. Refer all servicing to qualified personnel.

3. Contenuto della confezione
Verificare che tutti gli articoli siano presenti nel pacco:
- 1 x SHNITPWR Adjustable AC/DC Power Adapter
- 14 x DC Connector Tips
- 1 x Reverse Polarity Converter Cable
4. Istruzioni per l'installazione
Follow these steps to set up your power adapter:
- Verifica la compatibilità del dispositivo: Before connecting, confirm that your electronic device requires a DC input voltage between 4V and 24V and a current not exceeding 6A. Check your device's specifications or original power adapter.
- Select the Correct DC Tip: The adapter comes with 14 different DC connector tips. Identify the tip that matches your device's power input port. The original tip is 5.5x2.5mm. Other common tips include 6.5x4.4mm+Pin, 5.5x2.1mm, 5.5x3.0mm+Pin, 5.0x2.5mm, 6.3x3.0mm, 5.5x1.7mm, 4.8x1.7mm, 4.0x1.7mm, 3.5x1.35mm, 3.0x1.1mm, 2.5x0.7mm, Micro-B, Type-C, and a DC terminal connector for custom wiring.

Figure 4: Included DC Connector Tips and Polarity Converter
- Controllare la polarità: Most devices use center-positive polarity. If your device requires center-negative polarity, use the included reverse polarity converter cable. Connect the selected DC tip to the converter cable, then connect the converter cable to the adapter's output cable.
- Imposta Vol.tage (Before Connecting to Device): With the adapter unplugged from the wall outlet, rotate the voltage adjustment knob to the 'OFF' position. Then, connect the adapter's AC plug to a standard 100-240V AC wall outlet. The LCD display will illuminate. Carefully rotate the voltage adjustment knob to select the required output voltage for your device. The LCD display will show the current output voltage.
- Connetti al dispositivo: Una volta che il voltage is set and verified, connect the DC output tip to your electronic device.

5. Istruzioni per l'uso
After successful setup, operate the power adapter as follows:
- Accensione/spegnimento: The adapter can be turned on or off by rotating the voltage adjustment knob. Turn it to the 'OFF' position to power down without unplugging.
- Voltage Regolazione: Use the rotary knob to precisely adjust the output voltage from 4V to 24V. The LCD display provides real-time voltage letture.
- Monitoraggio: The LCD display continuously shows the output voltage, allowing you to monitor the power supply to your device.
- Gestione del carico: To ensure the longevity of the adapter and prevent overheating, avoid operating it consistently at its maximum 144W (6A) capacity. Maintain the load below 80% (approx. 115.2W).

6. Manutenzione
Proper maintenance ensures the longevity and reliable operation of your power adapter:
- Pulizia: Disconnect the adapter from the power outlet and all devices before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
- Magazzinaggio: Conservare l'adattatore in un luogo fresco e asciutto quando non lo si utilizza. Evitare temperature estreme e la luce solare diretta.
- Cura del cavo: Do not bend or crimp the power cables excessively. Avoid placing heavy objects on the cables.
7. Risoluzione Dei Problemi
If you encounter issues with your power adapter, refer to the following:
- Nessuna alimentazione/Display spento:
- Ensure the adapter is securely plugged into a working wall outlet.
- Controllare che il volumetage adjustment knob is not in the 'OFF' position.
- Verify the wall outlet is supplying power by testing with another device.
- Il dispositivo non si accende:
- Confirm the selected DC tip is firmly connected to your device and the adapter.
- Double-check that the output voltage displayed on the adapter matches your device's requirements.
- Ensure the polarity is correct for your device. Use the reverse polarity cable if necessary.
- Verify your device's current requirement does not exceed 6A. If it does, the adapter's over-current protection may activate.
- Test the adapter with another compatible device to isolate the issue.
- Surriscaldamento dell'adattatore:
- Reduce the load on the adapter. Ensure the connected device's power consumption is below 80% of the adapter's maximum capacity (115.2W).
- Assicurare un'adeguata ventilazione attorno all'adattatore. Non coprirlo.
- Vol. imprecisotage Visualizzazione: While the built-in display is generally accurate, minor discrepancies may occur. For applications requiring extreme precision, verify the output with an external multimeter.
