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.

So you want the power to the modem ie

12V * 1A = 12W

Then if you divide the power needed by the modem by the 5V of the powerbank you get:

12W / 5V = 2.4A

Now figure that the converter will also use / loose some power so you need a powerbank that supplies a minimum of 3A.

Which means that the powerbank you have is not large enough.
