The Power Bank comes in wonderful aluminum case and brings good 300g on the scales. The elegant design is topped off by the LCD display. Unfortunately, the performance is completely flawed! Charging takes almost a whole day. And then after two-time reloading a Samsung S3 mini (battery capacity 1500 mAh) from 30% to 100%, the Power Bank only 42% charge. Further tests have shown that the Power Bank can have a maximum of 6,000 mAh. Far too little of the weight and price.
