The Romoss SW20 Pro 20000mAh power bank is home to an enormous amount of power and a wide range of compatibility. It features one Type-C input/ouput port, two USB output ports, one Lightning input port and one Micro USB input port. This allows for simultaneous charge of three devices, which is well above the norm.
The Type-C import/output port and USB ports make use of the FitCharge+ technology. This enables the power bank to identify the current demand and any other charging requirements for the devices connected to it. Compatibility is rarely an issue for the Romoss SW20 Pro due to this.
