Can I Use a 100W Charger for a 65W Phone?

Modern phone chargers, employing USB Power Delivery (PD), possess the ability to dynamically adjust their power output. This dynamic adjustment enables a 100W charger to safely and effectively charge a 65W phone. However, the converse is not true; a 65W charger would be inadequate to power a 100W device.

Understanding Power Delivery

USB Power Delivery is a protocol that defines standardized voltage and current combinations for power delivery over USB cables. It allows devices to negotiate the appropriate power level they need and supports higher power outputs than traditional USB standards.

In the case of phone charging, a 65W charger can provide up to 65 watts of power, while a 100W charger can deliver up to 100 watts. When a 65W phone is connected to a 100W charger, the charger will detect the phone’s power requirements and adjust its output accordingly.

Safety Considerations

It is important to note that a 100W charger will only supply up to the maximum power that the connected device can handle. In this case, the 65W phone will only draw 65W of power from the 100W charger, ensuring safe and efficient charging.

Conclusion

In conclusion, using a 100W charger for a 65W phone is safe and effective, thanks to the dynamic power adjustment capabilities of USB Power Delivery. Conversely, using a 65W charger for a 100W device may result in insufficient power and slow charging. Therefore, it is important to select a charger that matches or exceeds the power requirements of the device being charged to ensure optimal performance and charging efficiency.
