Specifications

• Voltage: 19.5V
• Current (Amperage): 3.34A
• Wattage: 65W (derived from multiplying volts by amps)
• Connector Type: Large Barrel Pin (typically 7.4mm outer diameter with 5.0mm inner diameter)
• Pin Type: The connector is often referred to as a "large pin" or "big pin," typically a barrel connector with a center pin inside.

Compatibility

This type of power adapter is commonly used for mid-range Dell laptops, including:

• Dell Inspiron Series
• Dell Latitude Series
• Dell Vostro Series
• Dell XPS Series (Older models)

However, compatibility can depend on specific models, so it’s always best to check your laptop's model number. The 65W adapter is standard for laptops that don't require high power, such as ultrabooks or mid-performance machines.

Important Considerations

• Power Requirements: Ensure that your laptop requires a 65W (19.5V, 3.34A) adapter. Using an adapter with a higher or lower wattage could potentially cause performance issues or damage.
• Pin Size: The large pin (7.4mm) connector has a slightly different design compared to the newer smaller pin adapters (4.5mm or USB-C adapters). Make sure this fits your laptop’s power jack.

Identifying the Correct Adapter

1. Check Your Laptop’s Label: Look for the voltage and amperage ratings near the power input or on the original charger (if you have it). Ensure they match the 19.5V, 3.34A specs.
2. Look for Dell OEM Adapters: It’s always better to get an original equipment manufacturer (OEM) adapter to ensure quality and compatibility.
3. Fitment: Ensure the adapter's plug fits snugly into your laptop's power input. A large barrel pin is typically for older laptops, so newer models might need a different size.
