Excellent quality and great value for money
Arrived quickly, well packed and very nice. works perfectly ,but the only down is the voltage output is very low so it takes a very long time to charge compared to the 8 battery capacity one i ordered earlier.
Works perfectly. The only downside is the opening, which is very complicated. For beginners, you would need the help of an experienced person. Otherwise, it's a perfect product.
Very good power bank - case, just insert 8 cells and it works, I recommend it.
