Additionally, if you plan to upgrade to a more power-hungry device in the future, a higher-wattage charger can future-proof your setup.
What is the difference between a 45W and 65W charger?
The main difference between a 45W and 65W charger lies in their power output. A 45W charger is designed for smaller ThinkPad models that require less power, while a 65W charger is suitable for larger or more power-hungry devices. The higher wattage charger can also provide faster charging times for devices that support it.
In addition to power output, the two chargers may also have different connector types or polarity. For example, a 45W charger may have a smaller connector, while a 65W charger may have a larger one. It’s essential to ensure the charger you choose has the correct connector type and polarity for your ThinkPad model.
