Package contains:
• battery 5,200 mAh
• USB Type A-M / micro 5pin cable power adapter 15 cm long,
• a multilingual manual ENG/CZ/DE/ESP/FR/HU/IT/PL/RO/RU/SK/BG,
• packed in a cardboard box with a visibly presented product.
Notice: The actual (physical) cell capacity of this battery is 5,200 mAh. However, no external battery can transfer all the energy into the battery of a mobile device without losses. In power transmission, losses occur inside the voltage converter from 3.7 V to 5 V, on the transient resistances of contacts, due to lower efficiency of energy storage in the battery of the charged device, temperature conditions, higher charging current, and the like. The actual efficiency of this battery is around 84 % at a 1A discharge current, depending on the specified conditions.

FAQ
A): We recommend using the original micro USB cable supplied with the power bank.
B): The original cable has stronger conductors and less resistance. This minimizes charging losses. General cables for phones may have smaller diameter conductors, which may cause slower or interrupted charging. Such cables are designed for synchronization (data connection) and are not suitable for charging.
A): The capacity of the power bank is determined by the actual (physical) capacity of the battery cells that the power bank is equipped with.
B): The internal power bank batteries have a voltage of 3.7 V. To charge the phone, this voltage needs to be converted to 5 V, which is the standard for USB interface. In the charged device (such as a mobile phone or tablet), conversion from 5 V to 3.7 V is in turn needed to charge the internal batteries. With each voltage conversion, losses occur (most often in the form of heat), which are usually 5 to 15 %. As a result, the energy that the charged device is able to take is after necessary conversion of voltage of the two devices reduced by 2 x 5 % to 2 x 15 % and the efficiency of charging reaches 70 to 90 %.
A): Fast charging must be supported also by the equipment being charged - e.g. cell phone, tablet etc.
B): If charging from an external battery lasts approximately as long as from the charger, it means that the device does not have a fast charging function.
A): We recommend that you do not discharge the power bank completely to zero and do not let it run out of power for a long time.
B): If you want to extend the life of your power bank, do not discharge it to zero. It is good to leave about 10 to 25 % of its capacity. If the power bank is discharged, we recommend recharging it in the shortest possible time. Never store the power bank in a discharged state. As soon as you start charging the power bank, do not interrupt charging. Interrupted charging again reduces the life of your power bank.
