45W Dell AC adapter with 4.5×3.0 mm tip

This 45 watt power supply delivers 19.5 volts at 2.31 amps and accepts 100 to 240 volt mains input at 50 to 60 hertz. It fits Dell Inspiron 15 3000 models 3551, 3552, 3558, 3565 and 3567 plus many other Inspiron, Latitude, Vostro, XPS and Optiplex laptops listed in the compatibility data. The connector size is 4.5 by 3.0 millimetres.

Smart protection against wrong voltage.

Built-in safeguards labelled IV, SC and IO cut power if the adapter detects incorrect voltage, a short circuit or internal overheating. These features reduce the risk of damage to the laptop’s charging circuitry compared with unprotected units. The package includes the adapter and a detachable mains cord.

Simple plug-in replacement.

Installation is a direct swap: connect the mains cord, plug the barrel tip into the laptop and power on. The most common issue is ordering this 45 watt unit for a laptop that requires a higher rating or a different barrel size, which will prevent charging or cause the adapter to overheat. Check the original part number against the compatible list before purchase.

Questions about this item

Does the 4.5×3.0 mm connector wear out and need replacement?

The barrel connector is a standard passive part; it does not contain active components that degrade, so only physical damage would require a new adapter.

What limits continuous 45 W output during all-day use?

The adapter is rated for 45 W steady output; sustained loads at that level are within its design envelope.

How much heat or noise does the 19.5 V 2.31 A unit produce when running 24/7?

It uses passive cooling with no fan, so it runs silently; the case will become warm but stays within normal operating temperature for a 45 W supply.
