It is normal for a phone to heat up while using a power bank. The main reasons include energy conversion loss, using the phone while charging (such as playing games or watching videos), and high-temperature environments (such as direct sunlight or inside a car). To avoid overheating, keep both the phone and the power bank in a well-ventilated environment. If the device overheats, the charging power may decrease. In such cases, stop charging and allow the device to cool down before resuming. An increase in temperature is also a normal phenomenon in wireless charging. The product has passed safety certifications, so it can be used with confidence.
The decrease in capacity during charging is due to energy conversion and the circuit loss, typically resulting in a 34% to 45% loss. Therefore, a fully charged RAPID 5000mAh power bank can usually provide 2750mAh to 3300mAh of actual power to a device. To estimate the number of charges, please use the following formula: (Power bank capacity × 55%~66%) ÷ Device battery capacity ≈ Number of charges For example, a 5000mAh power bank charging a 3300mAh device can typically provide approximately one full charge.
Is it normal for the device surface to heat up under high power transmission. The device has multiple built-in protection mechanisms, the device can be used with confidence, users are abvised not touch it directly.
This charger is compatible with laptops, phones, tablets, earphones, smartwatches, gaming consoles, and other devices with USB-C or USB-A ports, such as MacBook Pro/Air, iPhone, iPad, Dell XPS, and Samsung Galaxy.
PogoPin is a magnetic contact charging method commonly used in modular connections, supporting high-efficiency, safe, and stable charging connections.
