Fast charging is a technology that allows electronic devices, such as smartphones and electric vehicles, to recharge their batteries more quickly than standard charging methods. By increasing the amount of electrical current delivered to the battery, fast charging can significantly reduce the time it takes to reach a full charge, often completing the process in under an hour. This technology typically requires compatible chargers and devices, which are designed to handle higher power levels safely. Many modern devices, including those from brands like Apple and Samsung, support fast charging, making it a popular feature for users who need quick power boosts throughout the day.
