What this adapter replaces

This 45W unit replaces a lost or damaged Dell charger that uses the 4.5x3.0mm round connector. It matches the 19.5V 2.31A output required by many Inspiron 11, 13, 14, 15 and 17 models across the 3000, 5000 and 7000 series as well as several XPS 13 units. The jump is worth it when the original brick fails or a spare is needed for travel.

Connector fit and the converter cable

Some Inspiron 3000, 5000 and 7000 laptops require the larger 7.4x5.0mm tip instead of the 4.5x3.0mm plug on this adapter. A converter cable is included in the package to bridge that difference, but only when the laptop side accepts the converter. Buyers who need the 7.4x5.0mm connector natively cannot use this unit without the adapter.

Input voltage range and fixed output

The adapter accepts 100-240V AC input at 50 or 60 Hz, making it usable worldwide with only a plug adapter. Output is fixed at 19.5V 2.31A delivering up to 45W; it does not negotiate other voltages. Laptops that demand higher wattage or a different voltage profile will not charge correctly from this brick.

Questions about this item

Does the 4.5×3.0 mm barrel connector match my Dell laptop charging port?

This adapter uses a 4.5×3.0 mm round connector. Some Inspiron 3000, 5000 and 7000 models need a 7.4×5.0 mm plug instead; a converter cable is included for those units.

What is the correct way to connect the two-piece power cord and adapter?

Plug the AC power cord into the adapter brick first, then insert the 4.5×3.0 mm tip firmly into the laptop. Reversing the order can leave the tip loose and cause intermittent charging.

When should I replace the AC power cord that ships with the adapter?

Replace the cord if the plug blades bend, the insulation cracks, or the connector feels loose in the wall outlet. The adapter itself is rated for 100–240 V input and 45 W output.
