Are you curious about 120W chargers and how they work with different phones? In this video, I will explain the science and technology behind 120W chargers and why they are faster and more efficient than other chargers. I will also show you how fast a 120W charger can charge a Xiaomi phone, and compare it with other chargers.
A 120W charger is a very powerful charger that can deliver up to 120 watts of power to a compatible device. This means that it can charge a phone battery much faster than a standard 5W or 10W charger. However, not all phones can use a 120W charger, and some may not benefit from it at all. The compatibility and performance of a 120W charger depend on the phone’s battery capacity, charging circuitry, and software.
The battery capacity of a phone is measured in milliampere-hours (mAh), which indicates how much current the battery can store and deliver. The higher the mAh, the longer the battery life. However, the mAh alone does not determine how fast a battery can charge. The charging speed also depends on the voltage (V) and the current (A) of the charger and the phone. The power (W) of the charger is the product of the voltage and the current: W = V x A.
A 120W charger can deliver a high voltage and a high current to the phone, but the phone may not be able to handle it. The phone has a charging circuit that regulates the voltage and the current that the battery receives. The charging circuit also monitors the temperature and the health of the battery to prevent overheating or overcharging. The phone also has a software that controls the charging algorithm and the charging profile. The charging algorithm determines how the voltage and the current change over time during the charging process. The charging profile defines the optimal voltage and current levels for the battery at different stages of the charging process.
Therefore, the phone and the charger need to communicate and negotiate the best voltage and current levels for the charging process. This is done through a protocol called Power Delivery (PD), which is a standard for fast charging devices. PD allows the phone and the charger to exchange information and adjust the power delivery accordingly. However, not all phones and chargers support PD, and some may have different versions or implementations of PD. This means that some phones and chargers may not be compatible or may not work optimally with each other.
According to some sources, a 120W charger can take a Xiaomi phone from 0 to 100 percent in less than 20 minutes. This is because the Xiaomi phone has a 4500 mAh battery that supports PD 3.0, which is the latest version of PD. The 120W charger can deliver up to 20V and 6A to the phone, which is the maximum power that the phone can accept. However, the phone does not use the full 120W throughout the charging process. The phone uses a charging algorithm that gradually reduces the voltage and the current as the battery gets fuller. This is to protect the battery from overheating or overcharging. The phone also uses a dual-cell design, which splits the battery into two cells that can charge simultaneously. This increases the charging efficiency and reduces the heat generation.
However, there is no such thing as the best wattage for a phone charger. The wattage of the charger should match the power rating of the phone battery. You can use a phone charger of any wattage, higher or lower, as long as it is certified and compatible with your phone. A higher watt charger may charge your phone faster, but it may also generate more heat and wear out your battery faster. A lower watt charger may charge your phone slower, but it may also preserve your battery life and reduce the environmental impact.
Some people may worry that a higher watt charger will damage the phone battery or reduce its lifespan. However, this is not true. The phone battery will only draw the current it needs from the charger, and the phone will regulate the charging speed and temperature to prevent overheating or overcharging. Therefore, a higher watt charger is safe to use, but it may not be necessary or optimal for your phone.
