45 W 19.5 V HP-compatible AC adapter

This 45 W charger delivers 19.5 V at 2.31 A through a 4.5 mm by 3.0 mm barrel connector. It suits owners of supported HP Stream, Pavilion, EliteBook, ProBook, Spectre, Chromebook and ZBook models who need a replacement or spare power supply.

100-240 V AC input for worldwide use

The adapter accepts AC 100-240 V at 50-60 Hz so it works on mains supplies across different regions without a voltage converter. A single unit therefore covers travel or relocation between compatible power grids.

4.5 mm x 3.0 mm barrel limits interchangeability

The fixed 4.5 mm outer and 3.0 mm inner diameters mean the plug fits only laptops designed for that exact connector size. Owners of devices with different barrel dimensions or USB-C charging cannot use this adapter.

Questions about this item

Will the 4.5 mm × 3.0 mm barrel connector need replacing after frequent plugging?

The connector is a standard 4.5 mm outer, 3.0 mm inner barrel; it is rated for normal daily insertion cycles and does not have a user-replaceable tip.

What limits continuous output before the adapter throttles?

The unit is rated for a steady 19.5 V at 2.31 A (45 W); sustained loads above that will trigger its internal over-current protection.

How hot or noisy does the 45 W brick get when left on all day?

It runs silently with no fan; under full 45 W load the case becomes warm but stays within normal operating temperature for a sealed adapter.
