Hello,
so I bought a step up convertor 5v to 9v-12v-20v... And I soldered it to my 5v power bank and took the output to power with it my 9 volt router in between electricity outage.
But as soon as I plug it in the router the batteries die out immediately in less than a second, from 5v to ~0.13 volt with no clear reason.
I tried another lithium batteries but the same issue happens.
Knowing that the step-up converter measures 9v at output before plugging it so it's working properly.
My router is havit 2 antenna input 9 volt 600mA
