You don’t need UPS for router if you already have home ups / invertor. Its safe to use router on home invertor / ups. Ofcourse if you already have home based battery inverter system then you don’t need min ups power backup. Just ask your electrician to enable the socket of router for inverter power whenever mains line go down due to power cut.

For those who need wifi switched on all the time mini UPS system are the best bet. Whether its work related or can’t keep without internet due to whatever reason you can make yourself to agree for. Mini works best for JioFiber Router or Airtel Xtreme Routers or you have Act wifi router or Bsnl fiber modem router even Excitel Fiber router can get full power backup with this mini ups system.

Most cheap desktop UPS have auto shutdown feature when overall load is too low. So we can’t use same UPS for routers unless one specifically knows that the auto shutdown feature is not present in the UPS or know how to disable it.
