2. Setup Instructions
Before connecting the adapter, ensure your device requires a 14V DC input and that the barrel connector dimensions and polarity match. This adapter typically features a 5.5mm outer diameter (OD) and 2.1mm or 2.5mm inner diameter (ID) barrel tip with center positive polarity.
Steps for Connection:
- Verify Device Compatibility: Check your device's power input specifications for voltage (14V DC), current (e.g., 850mA, 1A), and the required barrel connector size and polarity.
- Connect Barrel Tip: Insert the barrel connector of the UpBright adapter firmly into your device's DC input port.
- Plug into Power Outlet: Insert the AC plug of the adapter into a standard 100-240VAC wall outlet.
- Power On Device: Once connected, power on your device. The adapter should begin supplying power.
