How to choose a power supply for a laptop

If the charger from the laptop fails, then the problem needs to be urgently addressed, not delaying, since mini-computers will not be able to hold the charge in themselves for a long time and, accordingly, work will not continue without a new charger. How to choose a suitable charger will be written in this article.

What are the power supply: types

Between the power supplies can vary in several types of characteristics. The most tangible is the connector. If a user purchases a charger with an output not suitable for a laptop, he will not be able to connect the wire and, accordingly, charge his computer. A list of wire options with the respective laptop manufacturers:

  • 5.5x1.7. This output is used only by Acer products.
  • 5,5x2,5. Very popular among various manufacturers exit. It can be found at ASUS, Toshiba, Del, Lenovo, Fujitsu and HEWLETT-PACKARD.
  • 4.0х1.7. Only for HP.
  • 4.8 x1.7. Long but narrow entrance used by LG and Compaq.
  • 7.4х5.0. A connector that in rare cases is an alternative for Dell and HEWLETT-PAKARD.
  • 5.5х3.0. Original entry for Samsung.
  • 6.0х4.4. Exclusive only for Sony.

In order to find out which particular connector uses the mini-computer, just look at the instructions.

In addition to the plug, laptop chargers may also vary in voltage and resistance ranges, but these parameters are insignificant and approximately equal on different devices. If the voltage in the house where it is planned to use a laptop is not stable, then the presence of an adapter on the cable of the wire (rectangular parallelepiped, sometimes a cylinder in the middle of the wire) will provide insurance against combustion.

How to choose a power supply for your laptop

First of all, you should try to choose a power supply unit of the same manufacturer that once produced a model of a laptop that needs charging. If there are no such options in the access, then anyone using the same connector of the plug will do. The presence of the adapter is welcome. In general, the brand and the cost of the power supply have no fundamental value, only the type of connection is important.
