    Got this just for my ONT, gateway, and router. I have AT&T fiber internet which requires an indoor optical network terminator as well a gateway device. I use my own router (Asus RT-AC86U) and while powering all 3 devices with a load on them I can get roughly 30 minutes of backup time. More than sufficient for a short brown out or black out scenario. I don't have it connected to a PC or anything at this point, but I have tested it's capabilities by throwing a breaker and it works great. The only thing I would like to have seen is true sine instead of simulated sine. But it was cheap so I can't complain!

    Very happy with this device. Easy to hookup obviously. And yes, I did have some nasty storms come through and it did trigger the UPS. THANK YOU! No blips no hits ... Great. It's a winner!

    Ordered 2 online. Delivered on time by UPS. Nice profile for under desk or Television stand. Went to the wesite and downloaded the app. Connected the ups to the computer. App reconized it and you're done. Only problem is today's plug configuration variations on the devices you need to plug into it.

    Have this plugged into our AV closet for backup power for our modem, switch and Orbi Mesh system. Switches on if we ever lose power and my wife can keep working from home. Small and quiet.

    Grabbed this on sale. Usually I go with more “advanced” APC units, but this model from CyberPower has won me over with its understated reliability protecting a Mac Mini.

    Bought this as a battery backup for my wireless internet. I have had 5 power outages since then and it has kept everything up and running! Great product and its unique shape was perfect for fitting in a tight spot where my wifi is located.
