Online Lithium UPS Comparison for 120V Edge, IT, and Network Deployments
The Xtreme Power J90-2kLiD and the APC Smart-UPS Ultra SRTL2K2RM1UC are compact 1U online lithium UPS systems designed for space-constrained edge IT, network closets, and distributed infrastructure.
While both platforms deliver true online double-conversion protection, the J90-2kLiD differentiates itself with longer-life LiFePO₄ batteries, higher 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 deployments where uptime, thermal resilience, service life, and lifecycle cost matter, the J90-2kLiD delivers clear next-generation advantages.

2kVA 120V Feature Comparison
| Feature | Xtreme Power J90-2kLiD | APC Smart-UPS Ultra SRTL2K2RM1UC | J90 Advantage |
| Battery Chemistry | LiFePO₄ (LFP) with integrated BMS | Lithium-ion | Safer chemistry, longer service life |
| Battery Life | Up to 15 years / 3,000–5,000 cycles | 8–10 years typical | Lower lifetime cost |
| Capacity (VA / W @ 120V) | 2000 VA / 1800 W | 2200 VA / 1870 W* | Comparable usable power |
| UPS Topology | Online double conversion | Online double conversion | Equal zero-transfer protection |
| Form Factor / Mounting | 1U rack or wall mount | 1U rack or wall mount | Same deployment flexibility |
| Efficiency | 94.5% | 93.2% | Lower heat, lower operating cost |
| Outlet Control | Individually controllable (with Web/SNMP) | Not supported | Remote reboot reduces truck rolls |
| Network / SNMP | Optional (SNMP-2PV3) | Integrated | Modular vs bundled approach |
| Runtime Options | Internal + EBP (J90-EBP48) | Internal + EBP (SRTL50RMBP1U) | Scalable runtime on both |
| High-Temperature Rating | Up to 50 °C (122 °F) | Up to 40 °C (104 °F) | Better for hot edge spaces |
| 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 | 5-year limited | Longer standard coverage |
* APC watt rating varies by configuration.
