• Commonly 100-240V AC (50/60 Hz) to support worldwide usage.
2. Output Voltage:
• 5V DC (Direct Current) via the USB port.
3. Output Current:
• Maximum 1A (1000mA).
4. Power Output:
• 5 watts (calculated as 5V × 1A).
Features
1. Port:
• Single USB-A port for charging.
2. Compact Design:
• Small and lightweight, suitable for travel or minimal desk setups.
3. Compatibility:
• Compatible with most USB-powered devices.
4. Safety Features:
• Overcurrent protection.
• Short circuit protection.
• Overvoltage protection.
5. Materials:
• Fireproof PC casing.
6. Efficiency:
• Meets energy standards like DOE Level VI or EU Energy Efficiency regulations (varies by region).
Applications
• Charging basic devices such as:
• Small smartphones.
• Wearables (fitness trackers, smartwatches).
• Bluetooth headphones or earbuds.
• Power banks (slow charging).
• Suitable for environments where fast charging isn't necessary.
*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.
