Review on Portable battery Samsung EB-PЗ300, dark gray by Mateusz Daczka ᠌

I took a noname with an unknown small capacity as a replacement (I could not resist the merch), which charged 5% for half an hour. I did not regret that I took a Samsung so that the fast charging protocol was compatible with the phone. Heaven and earth! It charges really fast and charges itself. It is also friendly with other devices, I did not notice any noticeable changes in speed. I wonder how things will be with the loss of capacity, but only time will tell.
