120 Watt Charger

A 120W charger is significantly faster than many conventional lower-wattage chargers, such as 5W or 20W chargers. This is because a higher wattage means power is delivered at a much higher rate to the device. For example, it is claimed that you can fully charge a 4,600mAh Xiaomi 12 Pro in as short as 18 minutes using a 120W charger.

Yes, 120W fast charging can be safe, but you have to make sure that your charger is from reputable manufacturers like Anker and comes equipped with all the necessary safety features, like overheating protection, short-circuit protection, and so on. For example, the Anker 737 Charger (GaNPrime 120W) is equipped with ActiveShield 2.0 technology, monitoring the temperature in real-time to prevent safety hazards. On the other hand, a low-quality or unbranded charger can pose significant safety risks when operating at 120W and thus should be avoided.

Generally yes. Most phones nowadays have built-in mechanisms that enable them to charge at their maximum supported speed, even if they are connected to a charger that can deliver much more. So, if you are using a 120W charger to charge a phone that supports only 20W charging, the charger will just deliver 20W and leave the extra 100W of capacity unused.

No, a 120-watt charger should typically not affect battery life. Modern smartphones and laptops have advanced battery management systems that regulate charging to prevent overcharging and excessive heat, which are primary factors in battery degradation. However, always use reputable and quality 120w chargers for safety and efficiency.
