Hadepa 11-Y000 45W 19.5V 2.31A laptop charger

Hadepa 45W charger for HP Stream and Pavilion

The Hadepa 11-Y000 supplies 19.5 volts at 2.31 amps for a total of 45 watts. It matches the 4.5 by 3.0 millimetre blue-tip connector used by HP Stream 11, 13 and 14 models and a wide range of Pavilion x360 and Notebook 15 or 17 units. The adapter accepts 100 to 240 volt input at 50 to 60 hertz, making it suitable for worldwide travel. It replaces original part numbers such as 740015-002, L25296-001 and 854054-001.

45W output with 19.5V 2.31A limit

The unit delivers a fixed 45 watt maximum, so it comfortably powers ultraportables and convertibles that specify a 45 watt brick. Systems that require a 65 watt or higher adapter will not receive enough power and may throttle or refuse to charge. The 19.5 volt rail is regulated to 2.31 amps, giving no headroom beyond the rated load. Buyers whose laptop ships with a larger supply should not use this model as a primary charger.

Thermals and noise in daily use

The compact corded design relies on passive cooling, so it runs silently under normal loads. In typical office or web-browsing scenarios the case stays warm but not hot to the touch. Continuous full-load operation will raise the enclosure temperature further, though the adapter remains within its rated operating range. No fan or active cooling is present, eliminating mechanical noise entirely.
