A car wireless charger should not have a significant effect on the life of the car battery, as long as it is used properly and within the manufacturer’s recommended specifications.
When the car engine is running, the car battery is charged by the car’s alternator, which is designed to provide enough power to run the vehicle’s electrical system and charge the battery at the same time. The additional power required by the wireless charger is usually minimal compared to the power needed to run the car’s electrical system and should not significantly impact the car battery’s lifespan.
However, it is important to note that leaving the wireless charger plugged in when the engine is off can drain the car battery over time, just as leaving any other electrical accessory plugged in can. So, it’s important to unplug the charger when not in use, especially if the car will not be driven for an extended period of time.
In summary, a car wireless charger should not have any significant effect on the life of the car battery, as long as it is used properly and within the manufacturer’s recommended specifications.
