FAQ
Why does the power bank charge fewer times than expected?
Some energy loss (typically 30 - 45%) is normal during power conversion because of battery and circuitry design.
Why does charging stop at 80%?
Your iPhone may automatically stop charging at 80% to protect its battery from overheating, as part of iOS 17's thermal management strategy. Charging will resume once the device cools down. Moving it to a cooler spot can help speed up this process.
Is it normal for the power bank or connected devices to feel warm during charging?
Yes. It is normal for devices to generate heat during charging, especially when using your phone for gaming or video streaming. Use the product in a cool, well -ventilated place (32 - 77°F / 0 - 25°C) and pause use of devices that are charging.
Why does the charging power gradually decrease while recharging?
When the power bank is recharging, its input power may gradually decrease to prevent overheating, protect the battery, and maintain safe charging. For best results, use it in a cool, ventilated environment (32 - 77°F) and avoid charging other devices at the same time.
