    Used for systems that only need protection, not UPS. Good value and excellent construction.

    Overall, it's OK. However, there was one occasion in which the battery was supposedly fully charged, yet when there was a minor blackout, all devices connected turned off, then back on again. My expectations were that any device connected to the battery outlets wouldn't be affected at all with any power interruption. So far, six weeks later, no issues.
