Jonhon's EV chargers are built to last. With proper installation and regular maintenance, their AC chargers typically have a lifespan of 10 - 15 years, while DC fast chargers can serve for 8 - 12 years. The long lifespan is attributed to several factors. High - quality components, such as durable power semiconductors and robust connectors, are used to withstand the rigors of continuous operation. Advanced thermal management systems prevent overheating, which is a major cause of component degradation. The company also designs its chargers with modular structures, allowing for easy replacement of individual components in case of failure, further extending the overall lifespan of the charger.
