I want to power my WiFi modem with my powerbank and the modem's requirements is DC 12V-1A. But my Powerbank has DC 5V-2A that is why I will use a step up converter but how about the Amperes, how can I decrease it to 1A?
We have a terrible electric company and I want to make this so I can still use the internet while there is a power interruption and it takes 6 to 12 hours. Online classes are going on that is why I want to make this.
