Instructions
1
Gather information about different brands and modelspower adapters, especially for universal units. On the Internet, you can read customer reviews and consult with managers of specialized online stores.
2
When choosing an adapter, pay attention to thethe main characteristics are current strength and output voltage. Power supply units usually have an output voltage of 15-20 V. It is possible to have a spread of 1-2 V with a device, but no more. For large voltage variations, the power supply and the device may become unusable. A weak adapter will not spoil the laptop or netbook, but it will burn itself. Therefore, choose the best option.

If you choose an adapter with a power reserve, it will be more reliable, as it warms less and thereby serves longer.
6
Also, be sure to pay attention to such a parameter as the voltage polarity. It must coincide with the block Supply and a portable device. Otherwise, the power will not be supplied.
7
Find out which computer shop sells the selected adapter model Supply. Order the device. You can also buy these things in online stores.
