A mini-tower UPS with line interactive topology, the CyberPower Intelligent LCD Series BRG1000AVRLCD provides battery backup (using simulated sine wave output) and surge protection for desktop computers, workstations, networking devices, and home entertainment systems. The BRG1000AVRLCD uses Automatic Voltage Regulation (AVR) to correct minor power fluctuations without switching to battery power, which extends battery life. AVR is essential in areas where power fluctuations occur frequently. Two USB charge ports (2.1 Amp shared) rapidly power portable devices such as mobile phones, MP3 players, and cameras. The BRG1000AVRLCD comes with a five-year warranty (including coverage of batteries) and a $350,000 Connected Equipment Guarantee. 1000 VA load capacity - work without any interruption during power outages Prevent critical data loss by staying powered during a blackout with up to 600 W load capacity Keep your sensitive devices powered with a backup of up to 1 minute at full load
