- สายไฟสวิตช์: The rocker switch typically has three prongs. Connect the positive (+) input to one of the silver prongs, the positive (+) output to the other silver prong, and the gold prong to the negative (-) circuit.
- เชื่อมต่อส่วนประกอบ: Wire the positive terminals of the USB Charger, Voltmeter, and Power Outlet to the positive output of the rocker switch.
- การต่อลงดิน: Connect all negative terminals of the USB Charger, Voltmeter, and Power Outlet, along with the gold prong of the switch, to a common ground point or the vehicle's negative battery terminal.
- แหล่งพลังงาน: Connect the positive input of the rocker switch to a fused 12V/24V power source from your vehicle's battery or accessory circuit.
บันทึก: Always use appropriate gauge wiring and an inline fuse (not included) for protection against overcurrent. Consult a professional if you are unsure about electrical wiring.
4. การดำเนินการ
4.1 การเปิด/ปิดเครื่อง
Use the integrated LED rocker switch to turn the entire panel's power supply ON or OFF. The LED indicator on the switch will illuminate when power is active.
4.2 Using the Dual USB Charger
Plug your USB-compatible devices into either of the two USB ports. The charger automatically detects your device and delivers optimal charging speed up to 2.1A per port, with a total output of 4.2A.
4.3 Monitoring Voltage with the LED Voltmeter
The digital LED voltmeter continuously displays the real-time voltage of your vehicle's battery (5-48V). This allows you to monitor battery health and prevent unexpected power issues.

เล่มปกติtage ช่วง:
- ก่อนสตาร์ทรถ: 13.4V - 14.8V
- After starting the vehicle: 12.2V - 12.8V
หากมีเล่มtage drops below 12V, it indicates an abnormal voltage, and the battery should be checked or replaced as soon as possible.
4.4 Using the 12V Cigarette Lighter Socket
Insert any compatible 12V accessory into the cigarette lighter socket. Ensure the accessory's power requirements do not exceed the panel's maximum current rating.
5. ข้อมูลด้านความปลอดภัย
- ควรตัดการเชื่อมต่อแบตเตอรี่รถยนต์ทุกครั้งก่อนทำการซ่อมแซมหรือดัดแปลงระบบไฟฟ้า
- Ensure proper wiring polarity (positive to positive, negative to negative) to prevent damage to the device and vehicle.
- Use an appropriate inline fuse for the main power input to protect against overcurrent.
- Do not exceed the maximum current rating of the panel or individual components.
- Keep the rubber caps on the USB ports and cigarette lighter socket when not in use to protect against water and dust.
- This product is designed for 12V/24V DC systems only. Do not connect to AC power.
