According to the manufacturer, the QTshine solar power bank has a capacity of 26,800 mAh. It offers 2.1A per port. On board are two USB outputs (2.1A and 1.0A output) and one micro USB input (5V / 2.1A).
Our assessment:
Anyone who travels a lot and wants to charge their devices independently of the power grid will get a good, powerful device with this solar power bank with 26800mAh. In the customer reviews from Amazon, the good price-performance ratio and the very fast charging performance are particularly praised. As a small shortcoming, some buyers indicate the long charging time via the solar function: this can take up to two days. This is much faster via the power grid.
