P80AV-800 Pure Sine-Wave Line-Interactive Power Conditioner with Battery Back-Up For Audio Video Systems 

Now that the thunderstorm season is upon us, your electricity might be going out now almost everyday. Your cable box, AVR, and WiFi router lose power and it takes 10 minutes to re-boot. Sound familiar? 

Don’t let blackouts, brownouts, or power outages ruin your audio / video system. Connect up to eight components including the TV to the P80AV-800 (720 Watt) Power Conditioner / Uninterruptible Battery Power Supply to protect them from low-voltage / no voltage conditions. If the power goes out, the P80AV’s internal battery automatically keeps your AV system going for up to 15 minutes, giving you plenty of time to shut everything down in a safe and orderly fashion.  98% of all power failures are transient, over within a few seconds.
