An elegant power bank with a display indicating the current battery status as well as the voltage and current levels during charging the device. The small size and weight make the power bank easily fit in a purse or backpack. The 10,000 mAh capacity allows you to charge your smartphone several times. Has a flashlight. Capacity: 10,000 mAh Size: 105 * 65 * 23 mm Weight: 173 g Input voltage: 5V / 2A Output voltage: USB1: 5V / 2A, USB2: 5V / 1A 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.
