Can I Charge an iPhone 7 with an iPad Charger Safely?
When Apple introduces a new device with a higher wattage charger, many users wonder if they can utilize a more powerful charger for their older devices. In this article, we explore whether an iPhone 7 can be charged using an iPad charger safely.
The Compatibility Question
Yes, you can safely charge your iPhone 7 with an iPad charger. An iPad charger typically provides a higher wattage, ranging from 12W to 20W, while an iPhone 7's standard charger, on the other hand, is 5W. Despite the difference, your iPhone 7 has built-in mechanisms to regulate how much power it draws, ensuring it only uses the amount it needs to charge.
Benefits and Considerations
Using an iPad charger can result in faster charging times, particularly when your iPhone's battery is low. However, it's important to note that such a charger will not cause any harm to your device. The device will automatically draw the appropriate amount of power, so there is no risk of overcharging.
Faster Charging: The iPad charger, with its higher wattage, can provide a quicker charging experience. No Risk of Damage: Your iPhone 7 will only use the power it needs to charge, preventing overcharging. Consistent Power Draw: An iPhone 6 with a 50% battery and a 12W charger draws approximately 1.05 Amps, while the same phone with a 5W charger draws 0.95 Amps, indicating minimal difference in charging speed. Better Utilization for iPads: An iPad with a 70% battery can draw about 1.65 Amps with a 12W charger, demonstrating the charger's efficiency in fast charging iPads.It's worth noting that Apple specifically recommends using chargers designed for specific devices to ensure optimal performance and longevity. However, in the case of charging an iPhone with a more powerful charger, the device will still regulate its power usage effectively.
Apple's Official Recommendations
According to Apple, you can use 12W and 10W USB power adapters to charge your iPhone, iPad, iPod, Apple Watch, and other accessories like AirPods and Siri Remote. The device will only draw as much power as it needs, so there is no danger of overcharging.
When charging your devices, ensure you are using a compatible Lightning cable. The power adapters will automatically synchronize with the device and supply the appropriate amount of power.
Impact on Battery Longevity
While fast charging can affect a battery's longevity due to the heat generated, which can lead to wear and tear, for short durations, this impact is minimal. Apple recommends using chargers designed for specific devices for optimal performance and longevity.
In conclusion, while it is generally safe to charge an iPhone 7 with an iPad charger, it's important to ensure the charger and cable are compatible and to follow Apple's recommendations for optimal battery health.
