My Wireless Powerbank 10000mAh charges my smartphone too slowly. Why is this happening and what can I do?Updated 3 months ago

The SP-Connect Wireless Powerbank 10000mAh provides a maximum wireless charging output of 10W and has a 10,000mAh battery capacity. Its rated capacity – the usable output capacity available for charging your smartphone – is 5,800mAh. However, the actual charging speed depends on several factors and may vary depending on your smartphone and operating conditions.

Why is my smartphone charging more slowly than expected?

Charging performance is influenced 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: Wireless charging typically operates at an efficiency of around 70–75%. Some of the transferred energy is converted into heat instead of charging your smartphone.
• A small amount of energy also remains in the powerbank to protect the battery from deep discharge.

How to improve charging performance

• Start charging when your smartphone battery is at a low level. Charging speeds are generally highest at lower battery levels and gradually decrease as the battery fills to help protect it.
• Reduce your screen brightness or enable automatic brightness.
• Close unnecessary background apps.
• 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 powerbank's USB-C output, 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 wired connection, the powerbank may have a fault.

Please contact our Customer Support at [email protected] and provide the following information:

• Your smartphone model.
• The actual charging result (for example, from 20% to 70% until the powerbank was fully discharged).
• Your order number or proof of purchase.
• Your delivery address.
• Confirmation that you have already tried the recommendations listed above.

Summary

The charging speed of the SP Connect Wireless Powerbank 10000mAh depends on various technical and environmental factors. It features a 10,000mAh battery capacity and a rated capacity of 5,800mAh. Following the recommendations above can often improve charging performance. If charging remains unusually slow, our Customer Support will be happy to assist you.
