Choosing the right power adapter – key parameters.

When choosing a new power adapter, it is worth paying attention to a few key parameters: power (W), voltage (V) and current (A). The power of the new power adapter should be at least equal to the value on the laptop label – higher power is permissible and may reduce the load on the device. The voltage should be close to the value of the original power adapter (+/- 0.5V), and the current may be equal or higher. However, the most important thing is to choose the right plug – it must be identical to the one in the original power adapter. This model uses a 2.5 x 0.7 mm plug. Remember that an incorrectly selected power adapter can lead to damage to the laptop or shorten the battery life.
