A battery with a capacity of 50000 mAh (185 Wh) provides a constant energy supply for your mobile devices. Such a value allows you to replenish the battery level of your daily used equipment, such as a smartphone or tablet, multiple times. Thanks to the use of lithium-polymer cells (a modern cell with high energy density and stable power supply parameters), the device maintains its expected operational performance. Everything is enclosed in a casing measuring 150 × 68 × 67.3 mm and weighing 967 g.
The BA-15 powerbank is equipped with a practical set of connectors, utilizing the popular USB (Universal Serial Bus) standard. The user has at their disposal USB-C1 and USB-C2 input ports, which are used to charge the powerbank itself with parameters ranging from 5 V to 12 V. The output section, in turn, consists of USB-C2, USB-A1, and USB-A2 ports, giving the ability to power up to three devices at the same time. With a simultaneous load on all output ports (USB-C2, USB-A1, and USB-A2), the equipment delivers current with parameters of 5 V and 3 A.
The maximum power delivered by the device is up to 20 W, which translates into the efficient energy restoration of compatible electronics. Individual output ports operate with different current intensity and voltage values; for example, the USB-C2 port supports up to 12 V and 1.67 A, while USB-A1 reaches 10 V at 2.25 A. The diverse output current parameters allow for a better adjustment of power to the technological requirements of a given receiving device. Thanks to this, the charging process is carried out with appropriate efficiency, shortening the waiting time for a full battery.
The safety of everyday operation is guaranteed by an integrated set of protective mechanisms. The powerbank features overcharge and over-discharge protection, which protects the internal cells from faster wear. Additionally, the circuit protects against overload, overheating, and short circuits (a sudden decrease in the resistance of the electrical circuit that can lead to a failure). Such multi-level protection ensures the safe operation of the powerbank itself, as well as all devices connected to it.
