Charging station with two power banks included. It allows you to power two batteries at the same time so that the batteries can then be used to charge other devices. The large capacity of 5000 mAh of each of the two power banks allows you to charge devices multiple times. Wide compatibility: the set allows you to charge many different devices such as smartphones, tablets, digital cameras, smartwatches, portable game consoles. Small size and lightweight construction make the set easy to carry and does not take up a lot of space while used. Built-in security system (against overcharge and short circuit protection) ensures safe use and extends product life. Specification: Input (charging station): DC 5V / 3A (max) Output (charging station): DC 5V / 1.5A * 2 Input (powerbank): 5V 1.5A Output (powerbank): 5V 2.1A Charging time: 3-4 h Size (charging station): 143*46*22.5 mm Size (powerbank): 92*54*24 mm 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.
