I have a modem whose power adapter shows input voltage as 100V to 240V. In my place, we get 220V as a power supply in which it works okay. But when the power goes out and the inverter starts working then it does not work properly. The power light in the adapter keeps blinking and also the light in modem which shows the power supply keeps blinking. I checked the voltage in my socket and it was around 241V. So I think that because the voltage from the inverter is a little high so maybe the power adapter is not working properly. So maybe if I can reduce the input voltage to the adapter by a little then it will work properly. So I want little help on how to decrease the voltage by around 20 volts to bring the input voltage to around 220V.
I am a software engineer by profession but I have worked on embedded devices so adding some resistance came to my mind but I have done that when I worked with 5V or 9V battery. Also, I won't be comfortable using a transformer to decrease the voltage. So could anyone tell me if it even possible or not and if yes then how?
Thanks in advance.
