Replacement AC adapter for Dell laptops

This 65 W usbroway adapter supplies 19.5 V at 3.34 A through a 7.4 mm by 5.0 mm barrel connector with a three-prong inlet. It accepts 100 to 240 V AC input at 50 to 60 Hz and includes the AC power cord. The unit is new and carries built-in overload, over-voltage and short-circuit protection.

Who this suits and who it does not

Buyers replacing a lost or failed Dell charger matching the listed part numbers such as PA-12, LA65NS2-01 or 492-BBKH will find a direct fit. It is not for laptops that require a higher wattage, a different voltage or a USB-C power delivery connector.

Deciding specification: 7.4 mm by 5.0 mm connector

The barrel plug measures 7.4 mm outer diameter by 5.0 mm inner diameter, which must match the laptop’s DC jack exactly. If the original adapter uses a different connector size or a USB-C port, this unit will not connect.

Questions about this item

How much heat and power draw should I expect from the 65 W 19.5 V adapter when it runs continuously?

The adapter draws up to 1.5 A from a 100–240 V supply and delivers 19.5 V at 3.34 A, so sustained load is 65 W with built-in overload and over-voltage protection.

Which cables or cords must I already have to use this charger with my Dell laptop?

The package includes the AC adapter and a detachable AC power cord; you only need a wall outlet that accepts the 3-prong plug.

Will the 7.4 × 5.0 mm connector fit the charging port on my older Dell Latitude E6430?

Yes, the E6430 is listed among the compatible models and uses the same 7.4 mm × 5.0 mm barrel connector.
