The use of the highest quality modern lithium-polymer cells provides a capacity of up to 1,000 mAh, which even allows you to charge the device several times.The material of the device is stable, resistant to high temperatures and drop. The product packaged in the original packaging. Specification: Battery: Li-polymer batterry Capacity: 15,000 mAh Charging time of power bank: 8 h Single charge power: DC5V 2.4A Dual charging power: DC5V 3.0A (1.5A for each device) Input power: DC5V 2.0A Weight:304 g Size: 156.2×74,6×17.9 mm Power indicator: electronic display Battery life cycle: 500 Storage conditions: from -10 ° C to 40 ° C NOTE! Nominal capacity expressed in mAh (milliampere hours) means the sum of all cells that were used in the power bank. The cells used have a voltage of 3.6 – 3.7V, while the standard USB port – 5V, so voltage conversion is necessary, which in turn translates into real capacity. After conversion, it is usually around 65-67% of the original value. This means that for a power bank with a capacity of 12,000 mAh, in fact about 8,000 mAh is available.
