When a Dell laptop needs a replacement power adapter, a standard AC-only charger may not cover every power source required during mobile work. The DA65NS3-00 (DK138 / 0DK138) PA-12 Auto/Air adapter is a 65W AC/DC laptop power supply designed for compatible Dell notebooks. It delivers 19.5V DC at 3.34A and accepts 100–240V AC or a compatible 11–16V DC input when the appropriate cable and outlet are available.
Before ordering, compare the model number on your current adapter, the laptop's required voltage and wattage, and the 7.4mm × 5.0mm connector with its center identification pin. A matching barrel diameter alone does not establish full compatibility.

OEM and Replacement Compatibility
The DA65NS3-00 model appears in Dell regulatory documentation among Delta adapter models specified for certain Dell notebook platforms. Supplier catalog references associate DA65NS3-00 with DK138 / 0DK138 and the PA-12 Auto/Air 65W adapter family. These identifiers help match the replacement to the existing adapter; they do not establish that every power adapter in the PA-12 family is interchangeable.
Use the cross-reference only after checking your existing adapter label, output rating, connector dimensions, and center identification pin.

Frequently Asked Questions
How can I confirm that DA65NS3-00 / DK138 will fit my Dell laptop?
Check your existing adapter for DA65NS3-00, DK138 or 0DK138, then verify the 19.5V output, required wattage, 7.4mm × 5.0mm barrel size and center identification pin. Confirm your exact notebook model as well.
Can this adapter power a laptop from a car or an airplane outlet?
The Auto/Air design supports compatible 11–16V DC input when the correct DC cable and power outlet are available. Aircraft outlet types and availability vary. Do not connect the adapter to a DC source outside its specified input range.
Are the car and airplane cables included?
The adapter's Auto/Air designation does not by itself confirm the package contents. Check the exact kit description and included-accessory list before purchase if you need a vehicle or in-flight DC cable.
Can it replace any Dell 65W charger?
No. The laptop must accept the adapter's 19.5V output, the available current and power must meet its requirements, and the physical connector and center identification pin must be compatible. Other Dell 65W adapters may use different connectors or specifications.
Why might a laptop fail to recognize a replacement adapter?
A mismatched or damaged center identification pin, an unsuitable adapter, a defective cable, or a laptop charging-port issue can prevent proper recognition. Check compatibility and inspect the connector before assuming the laptop battery is faulty.
