Thinking about it a little more, if you are only powering your wifi Router you may be able to address your needs with a simple UPS device. I have one for my router and it does okay. The nice thing about a UPS is it has a built in battery, charger, and automatic transfer switch: https://www.amazon.com/APC-Battery-...&hvlocphy=&hvtargid=pla-4583932713467616&th=1
They have about 200 watt-hours of storage, so if your load is less than 20 watts it can cover about 10 hours.
I use one for my router
I tried to use one for the wife's CPAP machine (72 watts) and it was able to work for 3 hours and died. As a temporary solution I used a 12 volt 100 Ah battery and a 300 watt inverter, which could provide coverage for 2 nights, the inverter had USB charge ports, so we could charge a phone off it too.
Her oxygen machine draws 450 watts and the unit in the picture will only cover that for 1 night (10.5 hours) before depleting the batteries.
A single circuit automatic transfer switch adds about $80 a system.
I like measuring my energy consumption using a kill-a-watt type inline meter as part of my system sizing exercise.
