Dimensions are justified by capacity and power. With a huge capacity, in fact, it takes up to 4 hours from a full discharge and "to the ears", a very full charge - in 3 hours, but you need a separate external charging adapter for USB type C 65W or more for maximum charging speed. As stated in the description, when charging peripherals, the powerbank itself can also be charged from the network, which I also really liked. The type C output provides fast charging via the QuickCharge 2.0, PD 2.0, Huawei FCP (9V, up to 2A) protocols, the orange USB A (USB4) output also supports Huawei SCP (5V-4.5A / 4.5V-5A). Other protocols have not been tested.
