J90-3kLiD vs APC SMT3000RM2U
The Xtreme Power J90-3kLiD is a 1U online double-conversion lithium UPS; the APC SMT3000RM2U is a 2U line-interactive VRLA UPS. Both are 3000 VA / 2700 W at 120 V for edge IT, telecom, and network infrastructure. The J90 differentiates on topology, LFP battery life, efficiency, recharge, rack density, temperature, TAA, and warranty.
What the J90-3kLiD brings
- Online double conversion vs line-interactive (continuous conditioned power)
- LiFePO₄ batteries, up to 15-year life vs 3–5
- 1U vs 2U (higher rack density)
- Faster recharge (1 hour vs 3)
- Per-outlet control, 50 °C operation, TAA, 6-year warranty

- True online double-conversion protection
- Long-life LiFePO₄ batteries with fewer replacements
- 1U rack density and 50 °C operation
- Per-outlet control for remote reboot
- TAA compliance and a 6-year warranty
The APC SMT3000RM2U may fit if you need
- An environment standardized on APC infrastructure
- Line-interactive topology at lower up-front cost
- Consistent cooling and an existing battery-maintenance program
Frequently asked questions
Yes. The J90-3kLiD is a current-production 1U online lithium alternative to the 2U line-interactive SMT3000RM2U. It matches the 3000 VA / 2700 W rating while adding online double-conversion, up to 15-year LFP battery life, 50 C operation, per-outlet control, TAA, and a 6-year warranty, and it halves the rack height.
Topology and battery chemistry. The J90 is online double-conversion with LFP lithium batteries in 1U; the SMT3000RM2U is line-interactive with VRLA lead-acid in 2U. The J90 conditions power continuously, lasts longer, recharges faster, and runs to 50 C.
Roughly. Both deliver a few minutes at full 2700 W (about 4 for the J90, 3 for the SMT), and both extend with battery packs. The J90 recharges far faster (about 1 hour vs 3).
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.
Online double-conversion fully reconstructs the output waveform with zero transfer time, which protects sensitive edge and network loads from sags, surges, and frequency variation that a line-interactive unit passes through during normal operation.
