    The 4th one I have. They last - not as long you are expecting, but do the job at protecting your connected equipment from surges.

      The SE450G1 is a smaller standby unit. We do have bigger units that can provide more runtime if needed. Feel free to visit our website www.cyberpowersystems.com for more options. Thank you for your review! CyberPower
