Compatible HP 45W AC Adapter

This 45W 19.5V 2.31A AC adapter replaces original HP chargers including part numbers 741727-001, TPN-C125 and HSTNN-LA40. It suits HP Stream and 15-inch models such as 15-f387wm, 15-f272wm and 15-r132wm where a 4.5mm x 3.0mm blue-tip connector is required. The package includes one adapter and one AC power cord.

Thermals Noise and Power Draw

Input accepts AC 100-240V at 50-60Hz with a 1.3A draw, allowing worldwide use without a voltage switch. The unit meets CE, FCC and ROHS safety certifications for secure operation. No moving parts are present, so the adapter runs silently during normal charging.

Sustained Load Behaviour

Continuous 45W output at 19.5V 2.31A is maintained for daily charging and typical workloads. The 30-day money-back period and 12-month warranty cover defects under sustained use. Buyers who need a higher-wattage unit for larger HP laptops should verify their model requires only 45W before purchase.

Questions about this item

How do I install the Blueskysea 45W AC adapter and what step do people often get wrong?

Connect the AC power cord to the adapter, plug into a 100-240V 50-60Hz outlet, then insert the 4.5mm x 3.0mm blue-tip connector into the laptop; the step people get wrong is forcing the connector without aligning the interior 3.0mm diameter pin.

What maintenance or replacement will the Blueskysea 45W charger need later?

The adapter itself is maintenance-free; plan to replace the detachable AC power cord if the plug or cable sheath shows wear, and replace the whole unit if output drops below 19.5V 2.31A or the blue-tip connector becomes loose.

What limit shows up first on the Blueskysea 45W adapter under sustained use?

The 45W output ceiling at 19.5V 2.31A is the first limit; continuous loads at or near 45W will cause the unit to reach its thermal design threshold before any other constraint appears.
