This post will compare features of the Cyber Power Battery Backup with Surge Protection Model SX65OU 350 watts VERSUS the Cyber Power Battery Backup with Surge Protection Model EC850LCD EC Series 850 Watts.
I powered a: small lamp, TV, notebook, router, digital phone and 1 tablet for 2.5 hours using the CPBB
850 Watts during a power outage and experienced no problems. Two hours is above the indicated average usage information. Although the device states that the average runtime is 52 minutes, it truly depends the amount of power drawn. I used the CPBB
350 Watts during a power outage and I was able to power 3 Amazon Fire HD-10 tablets (only to 40%), 2 cell phones (100%), a router/modem, a small lamp and an Amazon Echo Show 5 for 2 hours. The CPBB
850 Watts has a significant watt advantage over the
350 Watts.
In addition, I highly recommend that you disable the sound alerts on the surge protector, via the PC app. If you do not disable the alerts, the device will make sounds all of the time, even when there is no outage.
They are both great products but the CPBB 850 Watts is superior. My advice, go bigger.
