Ranked #7 in Best UPS Battery Backups

CyberPower CP1500PFCLCD

2.9

$239.95as of Jul 7

The CyberPower CP1500PFCLCD is a line-interactive UPS designed for protecting high-end PC systems, offering 1500VA capacity and a comprehensive LCD display showing power statistics. Tom's Hardware noted its reliable protection features and user-friendly interface, though Custom PC Review pointed out the simulated sine wave output may not suit all sensitive equipment. The unit includes a 24.7 lb weight and 14.2 inch depth, making it suitable for desktop use but bulkier than some alternatives. It's best for users needing robust power protection for mid-to-high-end systems rather than those requiring true sine wave output.

Strengths

— Features line-interactive topology for reliable power protection
— Includes LCD display showing power statistics like voltage and frequency
— Provides 1500VA capacity suitable for high-end PC setups

Watch-outs

— Outputs simulated sine wave instead of true sine wave
— Battery replacement kit is lower capacity (8AH) than original (9AH)
— Larger physical footprint compared to some competitors

Eaton 5P 1550

4.0

$1,099as of Jul 7

The Eaton 5P1550GR is a rackmount UPS designed for data center environments, offering 1550 VA / 1100 W capacity with true sine wave output. Reviewers noted its compact 1U form factor and 6 C13 outlets with programmable groups for managing critical and non-critical equipment. The unit features ABM battery management technology that extends battery life and provides advance warnings for replacement.

How they stack up

CyberPower CP1500PFCLCD

The CyberPower CP1500PFCLCD offers a user-replaceable battery and LCD display, features not found in the APC Back-UPS Pro 1500VA. However, it's bulkier than the Tripp Lite SMART1500LCDT and outputs simulated sine wave instead of true sine wave, unlike the Eaton 5E 850LI which provides true sine wave output.

Eaton 5P 1550

The Eaton 5P 1550 offers a 1U rackmount form factor and true sine wave output, features not available in the Tripp Lite OMNI 1500LCD. However, it requires user intervention for battery replacement and has a shorter power cord compared to the more user-friendly APC Back-UPS Pro 1500VA.
