Using the wrong charger for your iPhone can result in charging failure, low charging efficiency and reduced battery life, or compromise your phone's safety. For instance, using iPhone adapters with incorrect voltage, such as laptop chargers, can overheat the battery and potentially cause a fire. On the other hand, using a low-current charger may result in slower charging or may not work at all.
It is crucial to use a quality and compatible Apple charger that meets the required standards, such as Anker 737 Charger (GaNPrime 120W), which is certified for charging iPhones, MacBooks, and other relevant devices simultaneously from a single charger.
