Ultra-Slim Lithium UPS vs Compact Desktop Lithium for Edge, IT, and Network Deployments
Both the Xtreme Power J60-350 and the Liebert Power-UPS Lithium (PUL-400LVT) from Vertiv are lithium-based UPS systems designed for edge IT, networking, and distributed infrastructure. While both target the sub-500VA class, they are engineered for very different deployment models.
The J60-350 is purpose-built as an ultra-slim, industrial-grade lithium UPS with integrated mounting and high-temperature tolerance. The Liebert Power-UPS Lithium is a desktop-style lithium UPS intended primarily for light office and IT environments.
Key differences appear in physical footprint, construction, mounting flexibility, battery lifecycle, temperature performance, and real-world deployability.
For modern edge, kiosk, and space-constrained installations where longevity and durability matter, the J60-350 delivers clear next-generation advantages.

Key Differentiators at a Glance
- Ultra-slim 1.2-inch profile designed for tight spaces
- LiFePO₄ (LFP) battery chemistry with dramatically longer service life
- Steel enclosure vs plastic construction
- Integrated mounting brackets included standard
- Up to 50 °C (122 °F) operation vs typical 40 °C limits
- Up to 2× battery cycle life
- Significantly smaller physical footprint
- Better suited for kiosks, wall-mount, and industrial edge environments
350VA Lithium UPS Feature Comparison
| Feature | Xtreme Power J60-350 | Vertiv Liebert PUL-400LVT | J60-350 Advantage |
| Battery Chemistry | Lithium Iron Phosphate (LiFePO₄) with integrated BMS | Lithium-ion (standard chemistry) | Safer chemistry with longer life and better thermal stability |
| Form Factor / Size | 1.2″ H × 8.5″ D × 6.9″ W (≈70 cu in) | 5.5″ H × 8.3″ D × 4.7″ W (≈214 cu in) | Roughly ⅓ the volume; fits where other UPS systems cannot |
| Construction | Steel enclosure | Plastic enclosure | Greater durability for edge and industrial locations |
| Mounting | Standard mounting brackets included | No standard mounting hardware | Wall, under-counter, and enclosure mounting out of the box |
| Battery Design Life | Up to 15 years | 8–10 years | Up to 50% longer service life |
| Battery Cycle Life | 3,000–5,000 cycles | ~2,000 cycles (typical) | Up to 2× cycle life |
| High-Temperature Operation | Up to 50 °C (122 °F) | Typically rated to 40 °C (104 °F) | Reliable operation in hot or poorly cooled spaces |
| Runtime (Typical Load) | ~6 minutes @ 200W | ~3 minutes @ 240W | Approximately double the runtime at comparable loads |
Where the J60-350 Excels
The J60-350 is engineered for environments where space, heat, and long-term reliability are the primary constraints:
- Edge and network closets with limited clearance
- Kiosks, digital signage, and point-of-use enclosures
- Wall-mount and under-counter installations
- Industrial or non-climate-controlled locations
- Distributed IT where battery replacement is disruptive
When the Liebert Power-UPS Lithium May Be a Fit
The Liebert Power-UPS Lithium may be suitable for:
- Desktop or shelf-mounted office IT
- Light-duty networking applications
- Environments with adequate space and cooling
- Shorter lifecycle expectations
Who Should Choose Which?
Choose Xtreme Power J60-350 if you need:
- An ultra-slim UPS that fits in tight or unconventional spaces
- Long-life LiFePO₄ batteries with minimal maintenance
- Operation in high-temperature edge environments
- Integrated mounting without accessories
- Industrial durability with steel construction
Choose Vertiv Liebert Power-UPS Lithium if you need:
- A compact desktop lithium UPS
- Basic edge or office protection
- A form factor optimized for shelf or desk placement
Typical Applications
- Network switches and small routers
- Wireless access points
- Digital signage and kiosks
- Security cameras and access-control devices
- Edge computing and IoT equipment
- Wall-mount and enclosure-based deployments
Final Takeaway
While both systems provide lithium-based backup power, the Xtreme Power J60-350 delivers a dramatically smaller footprint, longer battery life, higher temperature tolerance, and superior mounting flexibility compared to the Vertiv Liebert Power-UPS Lithium.
For modern edge, kiosk, and distributed IT deployments where deployability and lifecycle cost matter as much as VA rating, the J60-350 offers a clear advantage.
