Good to know

Check your laptop's power requirements before ordering. The 4.5mm x 3.0mm barrel connector with blue tip is common on many Dell models, but not all 45W Dell laptops use the same plug. The adapter works with 100-240V mains, so it can be used internationally with the appropriate AC power cord.
