APC's BE600M1 is excellent at providing battery and surge protection for the devices you use almost daily. That is your phone and possibly a tablet. However, it has enough power reserves to plug in a router and a single display. If you only plan to use the BE600M1 to power a Wi-Fi router, the unit will have enough juice to let you browse the internet in peace for several hours, even if the electricity in the rest of your house is gone.
