Choosing the right power adapter – simple and effective

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 given on the laptop label, and even higher – this will ensure less load and better cooling. The voltage should be close to the value of the original power adapter (+/- 0.5V), and the current can be equal or higher. However, the most important thing is the compatibility of the plug – it must be identical to the original. Remember to check the INPUT or OUTPUT markings on the bottom of the laptop or the nameplate of the old power adapter.

The power adapter is characterized by an output voltage of 19V and a current of 4.74A. It has a standard plug with a diameter of 5.5 x 1.7 mm, which guarantees compatibility with many Acer laptop models. The power cable is approximately 1.13m long, and the weight of the whole set is about 339g. The device is covered by a 3-year manufacturer's warranty, which confirms its high quality and reliability.
