Why is my power bank providing fewer charges than expected ?
The capacity reduction during charging is due to a 20% to 35% energy loss in the battery cells and conversion circuitry. Therefore, a fully charged iWALK mini Portable Charger offers an estimated 2750mAh to 3500mAh to power devices.
How many times this power bank will charge my iPhone when fully recharged ?
To estimate charges,use this formula:
(Power Bank Capacity × 0.66) ÷ Device Battery Capacity.
For example, an iPhone 15 with a 3,349mAh battery can receive about 0.88 charges from a 4,500mAh power bank (calculated as (4,500mAh × 0.66) ÷ 3,349mAh).
