  • Includes 10 built-in outlets with 5 battery-protected and 5 surge-only options
  • Features LCD screen with real-time UPS and power status including input voltage, output voltage, load percentage, and runtime
Watch-outs
  • Fan runs continuously after battery replacement, causing noise issues
  • Some users report difficulty with USB port recognition for certain devices

How they stack up

Eaton 5E 850LI

The Eaton 5E 850LI provides wide input voltage tolerance and HID-compliant USB interface, features not found in the APC Back-UPS 600VA. However, it suffers from unreliable USB control and poor customer service, unlike the more reliable Tripp Lite OMNI 1500LCD which offers better software support and consistent performance.

Tripp Lite SMART1500LCDT

The Tripp Lite SMART1500LCDT provides a built-in USB port for OS-level shutdown and an LCD screen showing real-time power status, features not available in the APC BR1500G. However, it has continuous fan noise issues and outlet spacing limitations that the Eaton 5P 1550 avoids with its rackmount design and better runtime options.
