   • Frequency: 50-60Hz.
   • Standard for most modern laptop chargers, allowing use in various regions.

2. Output Voltage:

   • 20V DC (direct current).

3. Current:

   • 3.25A.
   • This indicates the maximum current the charger can provide. It determines the charging speed and is matched to the device's needs.

4. Wattage:

   • 20V × 3.25A = 65W.
   • This is the total power output of the charger, which should match or exceed the wattage requirements of your device.

5. Connector Type:

   • USB-C Pin/Connector.
   • USB-C has become the standard for power delivery, allowing for more versatile charging and compatibility across different devices. It supports both data transfer and power delivery.

6. Compatibility:

   • This charger is designed primarily for Lenovo laptops, such as those in the ThinkPad series, which support USB-C charging. However, due to the use of the USB-C standard, it may also be compatible with other devices that support the same power input through USB-C.

7. Cable Length:

   • Typically around 1.5 to 2 meters (5 to 6.5 feet), depending on the specific model of the charger.

8. Safety Features:

   • Over-voltage protection: Prevents damage from excessive voltage.
   • Short-circuit protection: Shuts down the charger in case of a short circuit.
   • Temperature protection: Prevents overheating.
   • Over-current protection: Limits current to prevent overcharging or damage to connected devices.

Usage:

This charger is commonly used with Lenovo laptops that have a USB-C power input. Devices like the Lenovo ThinkPad X1 Carbon, Lenovo Yoga series, and other USB-C powered models are typical examples. It is also suitable for other USB-C PD (Power Delivery) compatible laptops and electronics.

Potential Issues & Troubleshooting:

1. Loose Connection: Ensure that the USB-C connection is securely inserted into both the charger and the laptop. Loose connections can result in intermittent charging or no charging at all.
2. Cable Damage: Check for visible signs of wear or fraying on the cable, as damage could prevent proper charging.
3. Overheating: Make sure the adapter has proper ventilation during use, as excessive heat can indicate a problem with the charger.
