HP/Compaq Pavilion N3390 AC Adapter

Power AC adapter, also known as laptop AC adapter, laptop adapter, AC adapter, or simply power adapter. Laptop AC adapter supplies power to your laptop computer, and at the meantime it also charges your laptop battery. You can use it even if you do not have a battery inside your laptop. It is the device that connects your laptop computer to the wall. It is the thing that you let your pet chew on and break. It is also the cord that you trip over, yet you can not live without it. The AC adapter includes an adapter "brick" and a power cord. Some adapters use 3-prong power cords while others use 2-prong. This is, however, not a critical specification of an AC adapter.

The most important aspects of your AC adapter is the output amperage and voltage (e.g., 15V,0.8A), as well as the connector "tip" that plugs into your laptop computer. Evidently if the tip does not fit your computer, nothing else matters. The output voltage has to be large enough to "push" electricity into your computer. The multiple of voltage and amperage is called wattage. For example, 15V 8A equals 120W (watts).
