I would like to share my impressions about the recently purchased product. Optimal mini power plant, well, qualitatively assembled. The battery works quietly, I did not notice overheating for all the time I use it. It meets all the declared characteristics. The set does not take up much space, the panel charges the battery, although it has not yet been possible to charge up to 100%, but it is enough for me to then charge phones, a tablet and even a laptop from the battery. Everyone is happy, it works great.
