Replacement charger for HP laptops
This 45W AC adapter supplies 19.5V at 2.31A through a 4.5mm x 3.0mm blue-tip connector with a centre pin. It fits HP Stream 11, 13 and 14 models as well as Pavilion x360 11, 13, 15 and 17 units. Envy, ProBook, EliteBook, Spectre and standard 14 and 15 notebooks are also supported.
Thermals noise and power draw
The unit delivers a steady 45W output for everyday computing without drawing excess current. Built-in smart chips guard against over-heating, over-charging, short-circuiting and voltage surges during continuous use. No fan is present so operation stays silent in any environment.
Compact build with detachable cord
A lightweight housing slips easily into laptop bags or backpacks for travel or office backup. The package includes a detachable mains lead so the adapter can be stored or replaced separately. Buyers who need a higher-wattage supply or a different tip diameter should verify their original charger before ordering.

Questions about this item
How do I install the 4.5 mm x 3.0 mm blue-tip connector and what step is often missed?
Align the centre pin with the laptop port and push straight in until it clicks; the step many miss is confirming the original charger also reads 19.5 V and 2.31 A before connecting.
What maintenance or replacement will the 45 W adapter need over time?
The detachable power cord can wear at the strain relief; replace it with any standard IEC C7 figure-8 lead if fraying appears, while the adapter body itself is maintenance-free.
What limit appears first when the charger runs continuously at full 45 W load?
Thermal protection activates first; the built-in smart chip shuts the unit down if internal temperature exceeds the safety threshold, then auto-resets once cooled.
