45 W 19.5 V HP AC Adapter

This 45 W AC adapter supplies 19.5 V at 2.31 A for HP laptops that charge through a 4.5 mm blue-tip barrel connector. It replaces a long list of original HP part numbers covering the 11, 13, 14, 15 and 17 series. The unit is sold new and ready for immediate use.

4.5 mm Blue Tip Connector

The decisive specification is the 4.5 mm by 3.0 mm blue-tip barrel plug; only laptops with that exact charging port will fit. Voltage and amperage are fixed at 19.5 V and 2.31 A, so the adapter cannot serve devices that require a different output. No other connector types or power ratings are provided.

For HP Blue-Tip Laptop Owners

Buyers with a compatible HP 11, 13, 14, 15 or 17 series laptop using the blue-tip port can use this adapter as a direct replacement. Users whose laptops need a different connector size, a higher wattage such as 65 W or 90 W, or a USB-C power input should look at other options.

Questions about this item

What does the 45W rating mean when the adapter is powering an HP laptop?

It supplies up to 45 watts at 19.5 volts and 2.31 amps, enough to charge and run compatible HP 11, 13, 14, 15 and 17 series models while in use.

What connector standard does the 4.5 mm blue tip use and what does it limit?

The 4.5 mm by 3.0 mm barrel plug fits HP blue-tip charging ports and limits the adapter to laptops that accept that exact tip size.

What physical clearance does the 4.5 mm blue-tip connector need to seat properly?

The straight 4.5 mm by 3.0 mm barrel requires a clear, unobstructed port on the laptop side so the tip can insert fully and lock in place.
