How to understand what power you need? You need to look at the voltage and current either on the device you plan to connect, say a Wi-Fi router, or on the power supply unit from it. For example, 12V and 0.5A is 6W (12*0.5) power. In this way, we sum up all the capacities of the devices that we plan to connect to the UPS. It is worth noting that the higher the power, the faster the UPS will discharge
