45W HP Laptop Charger with 4.5mm Tip

This 45-watt AC adapter supplies 19.5 volts at 2.31 amps through a 4.5 by 3 millimetre round connector. It is built for HP Pavilion and Stream laptops that ship with a 45-watt power requirement. The unit weighs 10.5 ounces and measures 4.26 by 1.81 by 1.38 inches.

Suitable for 45W HP Models Only

Owners of compatible Pavilion 15, 17 and Stream 11, 13, 14 series machines that specify a 45-watt input can use this charger. Buyers whose laptops demand 65 watts or more must select a higher-capacity adapter instead.

45-Watt Limit and Connector Fit

The adapter comfortably powers supported systems up to its 45-watt ceiling. It cannot charge any laptop rated above 45 watts, and the 4.5-millimetre tip will not mate with larger or smaller barrel ports.

Questions about this item

Does my laptop need a 4.5 mm round tip connector for this 45W adapter to work?

Yes, the adapter uses a 4.5 mm round tip connector. Your HP laptop must accept that exact size; it will not fit models that require a different connector.

Can I keep using my older 65W HP charger alongside this 45W unit?

No, this 45W charger is only for laptops that require 45W power. Using it on a 65W or higher system will not charge the battery.

How can I verify the adapter is delivering the correct 19.5 V output after I plug it in?

Measure the DC output with a multimeter set to volts; it should read 19.5 V at the connector when the adapter is powered.
