The HP 2R880AV is a 45 W AC adapter for powering HP notebooks. HP identifies this exact part number as a Smart nPFC RA adapter, so the model designation helps distinguish this version when matching an adapter to an HP notebook.
It provides 19 V output at 2.31 A. The black housing and right-angled connector identify its design; the angled connector can help route the cable alongside the notebook. It is intended for use as an external power supply at home or in an office.
