Have you lost or failed your notebook power supply, or do you need a spare? The Ewent EW3897 65W dedicated notebook adapter for IBM/LENOVO is a perfect replacement for the one that came with your notebook.
Robust and quality connectors
All Ewent notebook power supplies are made with solid and quality components, and fit perfectly into the power hole of the notebook. The EW3897 power supply is equipped with 2 connectors of the dimensions 7.9*5.5mm and 11*4.6mm (Square), suitable for IBM/LENOVO notebooks. This dedicated adapter automatically adjusts to the required voltage, thanks to its intelligent 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 and therefore the connector "fits", but also that the voltage indicated on the adapter connector is the correct one for your notebook . To know the voltage of each connector, please refer to the packaging or label of the original power supply.
Optimal for security
No concessions have been made for safety. The adapter has a quadruple intelligent protection system, which protects against overheating, overvoltage, over current and short circuits. Also, the charging board will stop charging when it notices that the battery is full.
How to calculate notebook wattage
To find out if the dedicated charger is suitable for your notebook, you need to calculate the wattage of the notebook. First check the original charger or the properties of the notebook. Then multiply the volts by the amperage to get the total wattage needed. For example: if your original charger has an output of 15V 3A, you need an adapter with a minimum power of 45 Watts (15V x 3A).
