Important Notes
Due to inherent energy loss during conversion—estimated at 20% to 35%—the actual usable capacity ranges between 2,880mAh and 3,500mAh. This means the number of full charges may vary slightly depending on your device’s battery size and usage patterns. When the power bank or connected device is below 30% charge, the output can reach maximum levels quickly, causing the unit to warm up noticeably. This is normal operation and not a sign of malfunction. To estimate how many times you can charge your device, use this formula: (Power Bank Capacity × 0.66) ÷ Device Battery Capacity ≈ Number of Charges. Please note that only the power bank, a USB-C cable, and a user manual are included in the package. No additional adapters, chargers, or accessories are provided unless specified separately.

Why is my Portable Charger providing fewer charges than expected?
The capacity reduction during charging is due to a20% to 35% energy loss in the battery cells and conversion circuitry. Therefore, a fully charged iWALK mini Portable Charger offers an estimated 2880mAh to 3500mAh to power devices.
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.
How can I estimate the number of charges for my device?
To estimate charging cycles, use this formula:
(Power Bank Capacity × 0.66) ÷ Device Battery Capacity ≈ Number of Charges.
