Best Wireless charger won't hurt Apple battery. Apple's official website clearly states that Apple devices and accessories comply with international standards for safety, electromagnetic compatibility, and electrical equipment. The Bex Wireless Charging Bank also meets these standards and certifications, while the Apple device has a smart protection function that automatically adjusts according to the charging current and voltage to protect the battery from overcharging and excessive current damage. Therefore, the use of BSI wireless charging bank will not cause damage to the Apple battery, but it is still recommended to choose a regular brand of charging bank to ensure safety.
