II. GaN Charger Overview

Explanation of the 65W power rating

The 65W power rating refers to the maximum amount of power that a charger can deliver to a device. In other words, a 65W charger can supply up to 65 watts of power to the device being charged. This is important because different devices have different power requirements, and if a charger cannot deliver enough power, it will charge the device slower or not at all.

For example, laptops typically require more power to charge than smartphones, so a 65W charger is ideal for charging a laptop quickly and efficiently. However, if you try to charge a smartphone with a 65W charger, it may deliver more power than the device can handle, potentially causing damage to the battery.

It’s also worth noting that the power rating of a charger doesn’t necessarily mean that it will always deliver that amount of power. Instead, it refers to the maximum amount of power that the charger is capable of delivering under ideal conditions. The actual power output may be lower depending on factors such as the device being charged, the charging cable used, and the ambient temperature.

Overall, the 65W power rating is an important factor to consider when choosing a charger for high-powered devices, as it ensures that the device can be charged quickly and efficiently.
