J90-3kLiD vs APC Smart-UPS Ultra SRTL3KRM1UC
The Xtreme Power J90-3kLiD and APC Smart-UPS Ultra SRTL3KRM1UC are both 1U online double-conversion lithium UPS at 3 kVA, 120 V. The J90 uses lithium iron phosphate (LFP) with an integrated BMS, the SRTL3K uses lithium-ion. The J90 leads on chemistry, battery life, efficiency, outlet control, temperature, TAA, and warranty; the APC carries slightly higher wattage and bundles network management.
What the J90-3kLiD brings
- LiFePO₄ (LFP) chemistry with integrated BMS vs unspecified lithium-ion
- Up to 15-year battery life vs 8–10
- Per-outlet control (the SRTL3K does not support it)
- Higher full-load efficiency (94.5% vs 93.2%)
- 50 °C operation, faster recharge, TAA, 6-year warranty

Specifications based on publicly available manufacturer documentation; confirm against current vendor data. The SRTL3K carries slightly higher rated wattage and bundles network management as standard.
Choosing between them
Both are 1U online lithium UPS. The J90-3kLiD leads on LFP chemistry, battery life, efficiency, outlet control, temperature, recharge, TAA, and warranty; the SRTL3K carries slightly higher wattage and includes network management as standard rather than as an option. Topology and form factor are equal.
Choose the J90-3kLiD if you need
- LFP chemistry and the longest battery service life
- Per-outlet control for remote management
- 50 °C operation in hot IDF/MDF and telecom spaces
- TAA compliance for regulated procurement
- A longer (6-year) standard warranty
The APC Smart-UPS Ultra SRTL3K may fit if you need
- Slightly higher rated wattage in 1U
- Bundled network management as standard
- Alignment with existing APC Smart-UPS Ultra deployments
Frequently asked questions
Chemistry and feature set. The J90 uses lithium iron phosphate (LFP) with an integrated BMS, rated up to 15 years; the SRTL3K uses lithium-ion (8 to 10 years typical). The J90 adds per-outlet control, 50 C operation, TAA, and a 6-year warranty; the SRTL3K carries slightly higher wattage and bundles network management.
Marginally the APC: 2880 W versus the J90’s 2700 W at the same 3000 VA. Size to your load; both are full 3 kVA-class units.
No. The SRTL3K does not support individually controllable outlets; the J90 does, with the Web/SNMP card, allowing remote reboot of specific loads to reduce site visits.
Yes. The J90 is TAA compliant (country of origin Taiwan), making it eligible for U.S. federal and regulated procurement; the APC unit is not.
