My Wireless Powerbank 5000mAh becomes warm while charging. Is this normal?Updated 3 months ago

Yes. It is normal for the SP-Connect Wireless Powerbank 5000mAh to become warm while wirelessly charging a smartphone.

Why does the powerbank become warm?

Wireless charging uses inductive charging technology, which is not 100% efficient by design. As a result, part of the transferred energy is converted into heat.

• The efficiency of wireless charging is typically around 70–75%, depending on the device and charging conditions.
• The remaining energy is dissipated as heat.
• As a result, both the Wireless Powerbank and your smartphone may become noticeably warm during charging.

This increase in temperature is expected and does not indicate a defect under normal operating conditions.
