My Wireless Powerbank 5000mAh charges my smartphone too slowly. Why is this happening and what can I do?Updated a month ago

The SP-Connect Wireless Powerbank 5000mAh provides a maximum wireless charging output of 10 W with a battery capacity of 5,000 mAh. However, the actual charging speed depends on several factors and may vary depending on your smartphone model and usage conditions.

Why is my smartphone charging more slowly than expected?

Charging performance can be affected by several factors, including:

• Your smartphone model and battery capacity
• Active features such as navigation, high screen brightness, or background apps
• Ambient temperature and direct sunlight
• Wireless charging technology: Inductive charging typically operates at an efficiency of around 70–75%. Part of the transferred energy is converted into heat instead of charging the battery.
• To protect the battery, a small amount of energy also remains in the powerbank to prevent harmful deep discharge.

How to improve charging performance

• Start charging when your smartphone battery level is as low as possible. Charging performance is typically highest at lower battery levels. As the battery fills, your smartphone automatically reduces the charging speed to protect the battery.
• Reduce the screen brightness or enable automatic brightness adjustment.
• Close unnecessary apps running in the background.
• Avoid direct sunlight and high ambient temperatures while charging.
• If possible, use airflow while riding to help cool both the smartphone and the powerbank.
• Whenever possible, charge your smartphone via the USB-C port of the powerbank, as wired charging is more efficient than wireless charging.

Is the charging performance still unusually low?

If charging performance remains unsatisfactory even when using a USB-C cable, the powerbank may be defective in rare cases.

Summary

The charging speed of the SP Connect Wireless Powerbank 5000mAh depends on several technical and environmental factors. Following the recommendations above will often improve charging performance. If charging remains unusually slow, our Customer Support team will be happy to assist you.
