Can I use 65W charger to replace 90W?

Using a 65W charger to replace a 90W charger is generally not recommended. The wattage rating of a charger indicates its power output capability. While it is typically safe to use a charger with a higher wattage rating than what is required, using a charger with a lower wattage rating can have some drawbacks.

When you use a charger with lower wattage, it may not provide enough power to charge your device efficiently, especially if your device requires a higher wattage charger. This can result in slower charging times or a device that doesn't charge at all while in use. Additionally, some devices may display a warning or error message when a charger with lower wattage is connected.

Furthermore, using a charger with lower wattage may not be able to support the full power requirements of your device during intensive tasks such as gaming or running resource-intensive applications. This can lead to the device drawing power from the battery instead of the charger, which can result in reduced performance or even battery drain.

To ensure optimal charging performance and to protect your device, it is generally recommended to use the charger specifically designed for your device or a charger with a wattage rating equal to or higher than what is recommended by the manufacturer. If you are unsure about the compatibility of chargers, it's best to consult the manufacturer's documentation or customer support for guidance.
