About Universal charger Ewent EW3966 65W 2 Conectores Black

Robust and quality connectors

All Ewent laptop power supplies are made with solid, quality components and fit perfectly into your laptop's power hole. The EW3897 power supply is equipped with 2 connectors in dimensions 7.9*5.5mm and 11*4.6mm (Square), suitable for IBM/LENOVO laptops. This dedicated adapter automatically adjusts to the required voltage, thanks to its smart technology that detects which connector is inserted. To find the connector you need for your notebook, we recommend that you check not only that the dimensions match, therefore the connector "fits", but also that the voltage indicated on the adapter connector is correct for your notebook. For the voltage of each connector, refer to the packaging or label of the original power supply.

ideal for security

No concessions were made for security. The adapter has a quadruple intelligent protection system, which protects against overheating, overvoltage, overcurrent and short circuit. Also, the charging board will stop charging when it senses that the battery is full.

How to calculate laptop power

To know if the dedicated charger is suitable for your notebook, you need to calculate the notebook's wattage. First check the original charger or laptop properties. Then multiply the volts by the amperage to get the total wattage you need. For example: if your original charger has a 15V 3A output, you need an adapter with a minimum power of 45 Watts (15V x 3A).
