Rechargeable hand warmer battery capacity description:
1.Battery capacity:
5200mAh Li-ion battery pack: Indicates the total capacity of the battery pack.
Capacity: 3500mAh: Actual usable capacity.
2. Input/Output :
Input: 5V/2A
Output: 5V/2A
3. Description:
· 5200mAh This product is equipped with a lithium-ion battery pack with a total capacity of 5200mAh, which is the theoretical total capacity of all the batteries inside the power bank.
Due to the energy conversion efficiency and internal circuit consumption, the effective capacity that can be provided to external devices in actual use is about
· 3500mAh. This design ensures the stability and safety of the product during use.
4. Rated capacity:
All 5200mAh power banks can only provide 60%-70% of their capacity to other devices, because about 30%-40% of the capacity is lost in circuit heat and voltage conversion. (Actual capacity = 3500mAh)

Please note that this product uses a lithium battery. When the ambient temperature drops below 0°C , the battery may experience a rapid loss of charge or a reduction in operating time. This is a normal physical characteristic of lithium batteries and does not indicate a product quality issue. In low-temperature environments, the activity of lithium ions within the battery decreases, increasing resistance and affecting performance. It is recommended that you keep this product warm in your pocket while using it and avoid prolonged exposure to low temperatures to ensure optimal performance.
