DELL 45W 3 Pin Adapter

This genuine DELL AC adapter delivers 45 watts of power through a three-pin connector. It is built for owners of compatible Dell laptops that require a 45W input. The unit is supplied new and ready for immediate use as a replacement or spare charger.

Suitable for 45W Dell laptops only

This adapter suits users replacing a lost or faulty 45W Dell charger with a matching three-pin tip. Buyers whose laptops require a higher wattage rating or a different connector type should look at other options. The fixed output makes it unsuitable for variable-voltage or USB-C charging needs.

45W fixed output rating

The single specification that determines fit is the 45 watt output. Only systems designed for this exact power level will charge correctly and safely. Verify the laptop's required wattage and connector style before purchasing.

Questions about this item

What does the 45 W rating mean for charging speed?

The 45 W output supplies up to 45 watts of power, which determines the maximum charging rate for compatible Dell laptops; actual speed depends on the laptop's power management.

What physical connector does this adapter use to fit the laptop?

It uses a 3-pin barrel connector that mates with the matching Dell power jack; verify your laptop's port shape before ordering.

How do I install this adapter, and what step is often missed?

Plug the AC cord into the brick, insert the barrel tip firmly until it seats, then connect the mains plug; the step often missed is fully seating the barrel so the pin makes contact.
