Technical Specifications

Input Voltage: 100–240V AC (universal input design, fully compatible with power grids across different countries and regions)

Output Voltage: Versatile voltage options are available, with mainstream selections including 12V, 15V, 19V and 20V. This wide voltage range makes the adapter well-suited for powering a variety of equipment such as desktop monitors, compact mini-PCs and comparable electronic devices.

Output Current:

4.42A output when working at 12V voltage

3.53A output under 15V voltage condition

2.63A output with 19V voltage input

2.65A output while operating at 20V voltage

All current values above are rated maximum outputs under stable load conditions, ensuring consistent power supply without current fluctuations. The adapter operates in constant voltage mode, so the output current will automatically adjust according to the actual power demand of the connected device (ranging from 0.01A up to the rated maximum value), which effectively prevents overload damage to the equipment.

**Power Adapter FAQ**

*1. What is a power adapter?*

A power adapter is a device that converts electrical power from a wall outlet (AC power) into a form suitable for electronic devices (DC power). It also adjusts voltage and current to match the requirements of your device.

*2. What's the difference between a charger and a power adapter?*

A "charger" includes circuitry to manage battery charging (e.g., for smartphones). A "power adapter" simply provides power without charging logic (e.g., for routers or monitors). All chargers are adapters, but not all adapters are chargers.

*3. What types of power adapters exist?*

- AC/DC Adapters: Convert AC to DC power.

- USB Adapters: Provide USB ports for charging (e.g., USB-A, USB-C).

- Travel Adapters: Change plug shape for international outlets (no voltage conversion).

- Variable Voltage Adapters: Allow adjustable output (e.g., 3V–12V).

*4. How do I know if an adapter is compatible with my device?*

Check:

- Voltage (V): Must match your device's input (e.g., 5V, 12V).

- Current (A or mA): Adapter's current should meet or exceed the device's requirement.

- Connector Size/Polarity: Tip size and polarity (e.g., center-positive) must match.

*5. What happens if I use the wrong adapter?*

- Overvoltage: May damage the device.

- Undervoltage: Device may not work or charge slowly.

- Incorrect Polarity: Risk of short circuits or permanent damage.

*6. Are third-party adapters safe?*

Yes, if they are certified (e.g., UL, CE, FCC) and match your device's specs. Avoid uncertified, cheap alternatives.

*7. Can I use a higher-amp adapter than required?*

Yes. Devices draw only the current they need. Ensure voltage matches exactly.
