45W 19.5V AC Adapter for Dell Inspiron

This 45-watt AC adapter delivers 19.5 volts at 2.31 amps to compatible Dell Inspiron laptops. It accepts a worldwide 100 to 240 volt input at 50 or 60 hertz. The unit is designed for owners of listed Inspiron 11, 13, 14, 15 and 17 models who need a replacement power supply. It is not for buyers who require a higher wattage output or a different connector type.

4.5 mm × 3.0 mm barrel connector fit

The critical specification is the DC connector with a 4.5 mm outer diameter and a 3.0 mm inner diameter. This tip size must match the laptop's charging port exactly for the adapter to function. The product is incompatible with several Inspiron 15 models including the 3520, 3521, 3531, 3542 and 3537. Buyers must verify their original adapter tip dimensions before purchasing.

Thermals noise and power draw in use

The adapter operates from a 100 to 240 volt AC source drawing up to 1 amp and supplies a steady 45 watt DC output. It has no internal fan so operation is silent. Normal warmth occurs during charging but the unit stays within standard limits for a 45 watt external power supply. No active cooling or unusual noise is produced.
