Yes, you can use a 100W charger for a 45W phone as the device will only draw the power it requires, regardless of the charger’s maximum output, and this will not cause any damage to the phone. The power regulation in the phone ensures that it charges at its maximum limit, which in this case is 45W, even when using a 100W charger.
Understanding Charger and Phone Compatibility
To understand why using a 100W charger with a 45W phone is safe, it’s essential to grasp how charging works. The charger does not push power into the phone; instead, the phone draws power up to its own limit. This means that as long as the voltage is the same, you can use any charger you want without worrying about damaging your device.
