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).

Getting hot when charing, is it normal ?

Our portablle chatger support 20W fast charging for your iPhone, which may cause some warmth,please feel free to use it since this power bank has built-in over-heat protection.

Why does the device become hot when used ?

When the power of the mobile phone or power bank is less than 30%, the power will reach the maximum value and the temperature of the product will rise rapidly and significantly. This is normal.
