Genuine HP 45W AC Adapter

The HP HSTNN-LA40 is a genuine 45W AC adapter designed to power compatible HP laptops and devices. It delivers a regulated 19.5V output at 2.31A for reliable operation. The unit accepts a universal 100-240V input at 50-60Hz for worldwide use. A power cord is included in the package for immediate connectivity.

Build integration and cable management

This adapter connects directly to the laptop barrel jack and a standard wall outlet via the supplied cord. Its 1.1A input draw at full load works with any standard household circuit without special wiring. The external brick design keeps heat outside the laptop chassis, freeing internal space and reducing system temperatures. No software drivers or BIOS updates are required for basic charging function.

Sustained load behaviour

Built-in safeguards protect against incorrect voltage, short circuit and internal overheating during continuous operation. The adapter maintains a steady 45W output as long as the connected device demands it, within thermal limits. Minor cosmetic wear may be present on the housing from inspection and handling, but electrical performance meets manufacturer specifications. It is not intended for devices requiring higher wattage or proprietary communication protocols.

Questions about this item

What is the maximum continuous output this 45W adapter can sustain without overheating?

The adapter delivers 19.5 V at 2.31 A for a total of 45 W and includes internal overheating protection that will shut it down if thermal limits are exceeded.

How much heat and noise does the power brick produce during all-day operation?

The unit has no fan so it runs silently; warmth is normal at full 45 W load but the built-in safeguards prevent excessive temperatures.

Which AC mains cable is needed to connect this charger to a wall socket?

A standard IEC C7 figure-8 power cord is supplied in the box and plugs directly into the adapter's inlet.
