### ⭐⭐⭐⭐⭐ Works for my intended use. Emergency power for modem/router
*by K***1 on 19 January 2025*

So I tend to try to prepare for the worst case scenario and since I have some massive power banks. I figured if I could power my modem router in a power outage without using my generator this would be perfect. I purchased a asus router that I just keep around to connect to my phone mobile data to run my essentials during a power internet outage. Usb tethering making for a much more reliable service then just a Hotspot. Helping with streaming and keeping everyone from going crazy on me. If this is your way of thinking this will work for the said application.
