Online Lithium UPS Comparison for 120V Edge, IT, and Network Deployments

The Xtreme Power J90-3kLiD and the APC Smart-UPS Ultra SRTL3KRM1UC are compact 1U online lithium UPS systems designed for high-density edge IT, network closets, and distributed infrastructure where space, heat tolerance, and lifecycle cost matter.

While both platforms provide true online double-conversion protection, the J90-3kLiD differentiates itself with long-life LiFePO₄ batteries, higher operating temperature tolerance, optional outlet-level control, full TAA compliance, and a longer standard warranty—making it better suited for mission-critical and regulated environments.

For modern edge and network deployments requiring maximum usable power in 1U with long service life and reduced maintenance, the J90-3kLiD delivers clear next-generation advantages.

Recharge Time (to 90%) ~1 hour ~1.5 hours Faster recovery after outages
TAA Compliance Yes (COO: Taiwan) No (COO: Philippines) Federal procurement eligible
Warranty 6-year UPS & battery (USA & Canada) 5-year limited Longer standard coverage

Where the J90-3kLiD Excels

  • High-density edge IT and network racks
  • Deployments requiring maximum usable wattage in 1U
  • Hot IDF, MDF, and telecom spaces with limited cooling
  • Distributed sites requiring remote outlet-level control
  • Government, public sector, and regulated procurement
  • Applications where battery replacement is disruptive or costly

When the APC Smart-UPS Ultra May Be a Fit

  • Organizations standardized on APC Smart-UPS Ultra platforms
  • Environments that do not require TAA compliance
  • Deployments preferring bundled network management
