1. Capacity
Measured in milliampere-hours (mAh), the capacity of a power bank determines how much charge it can provide. For iPhones, a power bank with a capacity of 10,000 mAh or more is ideal. This capacity typically offers at least two full charges for most iPhone models.
2. Portability
While a higher capacity is beneficial, it often comes with increased size and weight. Look for a power bank that strikes a balance between capacity and portability. A compact, lightweight power bank is easier to carry around and use on the go.
3. Charging Speed
Charging speed is influenced by the power bank’s output in watts (W). Faster charging requires higher wattage. For iPhones, which support fast charging, look for power banks with at least 18W output. This ensures your device charges quickly, minimizing downtime.
