J90i-3kLiD vs APC Smart-UPS Ultra 3000VA (208/230V)
The Xtreme Power J90i-3kLiD and APC Smart-UPS Ultra SRTL3KRM1UWC are both 1U online double-conversion lithium UPS for edge IT, networking, and distributed infrastructure at 208/230 V. The J90i-3kLiD leads on LFP chemistry, battery life, efficiency, outlet control, temperature, TAA, and warranty. Note the APC carries a higher wattage rating (3000 W at unity power factor) than the J90i-3kLiD (2700 W); size to your real-power load.
What the J90i-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 92.7%)
- 50 °C operation, faster recharge, TAA, 6-year warranty
Side-by-side specifications

| Recharge time | Approx. 1 hour | Approx. 1.5 hours | J90i – faster recovery |
| Battery life | Up to 15 yr / 3,000–5,000 cycles | 8–10 yr typical | J90i – lower lifetime cost |
| Outlet control | Individually controllable (Web/SNMP) | Not supported | J90i – per-outlet remote reboot |
| Communications | USB (HID), RS-232, optional Web/SNMP | USB (HID), serial, SmartConnect cloud | On-prem SNMP vs cloud |
| TAA compliance | Yes (COO Taiwan) | No | J90i – federal procurement eligible |
| Warranty | 6-year UPS & battery | 5-year limited | J90i – longer coverage |
Specifications based on publicly available manufacturer documentation; confirm against current vendor data. The APC SRTL3KRM1UWC carries a higher rated wattage (3000 W at unity power factor) than the J90i-3kLiD (2700 W); size to your real-power (watt) load.
Choosing between them
Both are 1U online lithium UPS at 208/230 V. The J90i-3kLiD leads on LFP chemistry, battery life, efficiency, outlet control, temperature, recharge, TAA, and warranty. The APC carries higher rated wattage (3000 W, unity PF) and bundles native cloud monitoring. Topology and form factor are equal.
Choose the J90i-3kLiD if you need
- Online protection rated for high-temperature (up to 50 °C) operation
- Long-life LiFePO₄ batteries with fewer replacements
- Per-outlet control to cut service visits
- TAA compliance for regulated procurement
- A longer (6-year) standard warranty including battery
The APC Smart-UPS Ultra 3000VA may fit if you need
- Higher real power in the 3 kVA class (3000 W, unity PF)
- Alignment with an APC / Schneider-standardized environment
- Native cloud monitoring (SmartConnect)
Frequently asked questions
Yes. Both are 1U online double-conversion lithium UPS at 208/230 V, delivering continuous regenerated power with zero transfer time. The differences are battery chemistry, temperature rating, efficiency, outlet control, and warranty rather than topology.
The APC SRTL3KRM1UWC is rated 3000 W (unity power factor) versus 2700 W on the J90i-3kLiD at the same 3000 VA. If your watt load is near 3 kW the APC has more headroom; the J90i-3kLiD is optimized for lifecycle and 50 C operation. Size to your real-power load.
The J90i-3kLiD uses lithium iron phosphate (LFP) with an integrated BMS, rated up to 15 years or 3,000 to 5,000 cycles at up to 50 C. APC specifies lithium-ion without naming the chemistry, roughly 8 to 10 years at up to 40 C. LFP runs cooler and tolerates more cycles.
Yes. The J90i-3kLiD is TAA compliant (country of origin Taiwan), making it eligible for U.S. federal and regulated procurement. The APC Smart-UPS Ultra is not TAA compliant.
