Laptop AC Adapter Purchase Guide:

Laptop AC adapter can be divided into original and non-original. Original HP ProBook 4421s power supply is designed by laptop manufacturers for their own specific models, but generally produced by other manufacturers and more expensive. The AC adapter is often not designed for specific notebook models, only the interface, voltage, current etc are compatible, which means that within a certain range they are universal.

  1. Must be clear about the battery charger AC adapter input voltage range. The best is the world's universal 100V ~ 240VAC.
  2. In the power side to leave a margin. Different AC adapter can be mixed use, but the basic principle is the large nominal current laptop AC adapter can replace the small nominal current HP ProBook 4421s AC Adapter, because the large nominal current power adapter with enough current margin, when replace a small nominal current power supply will not overheat or output low voltage. On the contrary, if you use a small nominal current power adapter instead of a large one to use, there may be overheating, causing aging or even lead to wire line burning, it's potentially dangerous to users.
  3. Must be clear about the power adapter output voltage and current. Best to select the products that nominal voltage and current are fully consistent with original laptop ac adapter. Although the adapter output voltage and current have a small change range, the overcurrent / overvoltage protection points are accurate test set by the manufacturer, different laptop with different load resistance, once the notebook computer has some circuit failures, the power adapter can play a protective effect. If you use a non-nominal voltage / current HP ProBook 4421s charger, then for its overvoltage / overcurrent protection set point is different, it could not protect the notebook.
  4. The AC adapter for HP ProBook 4421s interface of different brands are dissimilar, to make it clear about the power adapter pore size of DC output line.
