How many times can I charge my phone with this power Bank?

A 5,000mAh power bank typically provides about 3,000 to 3,300mAh of usable power due to energy loss during the charging process. It can charge a device like the iPhone 15 Pro (3,274mAh) approximately one time.

Energy is primarily lost during the following stages of the charging process:
1. Conversion in the Power Bank: The battery's voltage is converted to match the input voltage required by your device.
2. Conversion in the Device: Your device then converts the incoming voltage again to match its own battery cells.
3. Additionally, a small amount of power is lost through the resistance of the charging cable or extra heat generated.

These factors result in an industry-standard energy loss of about 30%–40%, which is completely normal and not considered a defect.

Tip: For the best performance, try to avoid using your phone heavily during charging and keep the power bank stored at room temperature.
