What this adapter powers

This 45W AC adapter supplies 19.5V at 2.31A to compatible HP laptops through a 4.5×3.0mm blue-tip connector. It replaces the original charger for Stream, Pavilion, Envy x360 and EliteBook Folio models listed in the compatibility data. The unit accepts 100-240V 50-60Hz mains input and includes the mains power cable.

Build integration and cable reach

The 8.8ft total cable length gives flexibility for desk, meeting-room or travel setups without needing an extension lead. A single barrel plug connects to the laptop; the bundled mains cable plugs into any standard wall outlet. No extra modules, docks or proprietary bricks are required to deliver the rated 45W output.

Sustained-load behaviour

Multiple intelligent protection circuits guard against over-voltage, over-current and short-circuit conditions during continuous operation. The adapter is designed to maintain a steady 19.5V 2.31A output while the laptop charges and runs demanding tasks simultaneously. It ships new with a 12-month warranty period.

Questions about this item

How long can the 45W adapter run continuously before thermal limits engage?

The unit has no stated thermal-limit duration; its multiple intelligent protections shut it down if internal temperature exceeds safe levels.

What is the fan noise level and surface temperature when the charger operates at 19.5V 2.31A all day?

The adapter uses passive cooling with no fan, so acoustic noise is negligible and the case remains warm but within normal operating range.

Which mains plug type must I already have for the included power cable to connect?

The supplied mains lead fits a standard UK three-pin socket; other regions require a suitable travel adapter.
