45 W AC adapter for HP laptops

This 45 W AC adapter delivers 19.5 V at 2.31 A through a 4.5 mm by 3.0 mm barrel connector. It replaces the original charger for many HP Spectre x360, Stream, EliteBook Folio, Split, Pavilion x360 and TouchSmart models. The unit accepts 100 to 240 V input at 50 to 60 Hz for worldwide use.

3.9 ft power cord and barrel plug

A 3.9 ft extended power cord is included, giving extra reach from wall outlet to desk. The fixed barrel plug matches the 4.5 mm by 3.0 mm jack used on the listed HP notebooks, so no separate tip is required. The adapter body is compact and runs without a fan.

Replaces lost or worn OEM chargers

This adapter matches the voltage, current and connector of the original HP 45 W units such as part numbers 740015-002, 741727-001 and PA-1450-56HA. It is not suitable for laptops that require a higher wattage or a different connector size.

Questions about this item

What output voltage and current does the 4.5 × 3.0 mm barrel connector deliver?

The adapter supplies 19.5 V at 2.31 A through its 4.5 mm outer, 3.0 mm inner barrel plug, giving a 45 W maximum.

What physical clearance does the 4.5 × 3.0 mm plug need at the laptop side?

The straight barrel jack requires only the depth of the laptop’s 4.5 mm × 3.0 mm DC socket; the brick itself measures roughly 100 × 40 × 30 mm and sits on the desk.

Which step do buyers often skip when fitting this charger?

Confirm the laptop’s original adapter shows exactly 19.5 V, 2.31 A and a 4.5 × 3.0 mm tip before plugging in; mismatched voltage or tip size will prevent charging.
