Dell 65W 4.5mm laptop charger

This 65W AC adapter delivers 19.5V at 3.34A through a 4.5mm by 3.0mm barrel connector. It supports a wide input range of 100 to 240V at 50 to 60Hz. The unit is compatible with numerous Dell Inspiron and Latitude models listed in the specifications. It serves as a direct replacement for original Dell chargers with matching part numbers.

Build quality and daily use

The adapter weighs 0.308 kilograms and includes a detachable three-prong AC power cable. Its 4.5mm by 3.0mm connector fits many Inspiron 3000, 5000 and 7000 series laptops, though some models in those same series require a larger 7.4mm by 5.0mm plug. Buyers must verify the connector size before purchasing to avoid a physical mismatch. The corded design allows the cable to be replaced separately if damaged.

Upgrade context and limits

This charger replaces lost or failed 45W or 65W Dell adapters that use the 4.5mm connector and 19.5V output. It also covers compatible part numbers such as LA45NM140, DA45NM140 and HA65NS5-00. It is not suitable for Dell laptops that require the 7.4mm by 5.0mm barrel plug or a different voltage. Buyers needing higher wattage or a different connector type should look elsewhere.

Questions about this item

What connector standard does the 4.5 mm × 3.0 mm barrel plug use and what power does it deliver?

The 4.5 mm × 3.0 mm barrel connector supplies 19.5 V at 3.34 A for a 65 W output and is backward compatible with 45 W Dell systems.

What physical clearance and weight should I allow for the adapter brick and its 3-prong mains lead?

The unit weighs 0.308 kg and ships with a standard 3-prong AC cable; the brick fits typical laptop-bag compartments and requires a 100-240 V wall outlet.

How do I install the charger and which step is most often missed?

Plug the 3-prong cable into the adapter, connect the barrel tip to the laptop, then insert the mains plug into a 100-240 V socket; the step users skip is seating the barrel fully until it clicks.
