HP Elitebook 820 G3 Original Charger, Ac Adapter And 3Pin Plug Black

Tips for how to choose the right power adapter/charger for your laptop:

• Please make sure the power adapter’s Output & Connector Size are matching your original Adapter’s.
•  Output Voltage and polarity must match with your old adapter.
•  Output Current is not as critical as output voltage, you could select either same or higher output current adapter.
•  If the previous three notes are the same as your adapter, you can be sure our adapter is compatible, even if your model is not listed.
• You can check with the Output Voltage and Output Current on the label of your original charger or the bottom/back of your laptop. As to the polarity (connector size) you can measure it or compare with ours.
