10 Best Computer Ups 2025 in the United States

The EF ECOFLOW DELTA 3 Plus is a powerful portable power station with a 1024Wh LiFePO4 battery, offering a solid 1800W AC output and multiple fast charging options including AC, solar, and even an alternator. Its 10 ms UPS switch-over time means it's quick enough to protect computers and sensitive equipment from sudden power loss, which is a key feature for anyone needing reliable backup power. The device can power up to 13 appliances simultaneously, making it versatile for home backup, camping, or RV use.

Its durable battery is rated for 4000 cycles (about 10 years), providing long-term reliability and the IP65 rating adds water and dust resistance, which is great if you take it outdoors. The smart energy management app helps monitor usage and customize settings, adding convenience and helping to save energy. One downside is its weight at 27 pounds, which is on the heavier side for portability, although still manageable. The expandable battery option is a nice plus if you want more capacity in the future.

This power station is an excellent choice if you want a UPS that also serves as a versatile portable power source, especially if you value fast charging and robust battery life.

The Vertiv Liebert GXT5 UPS is a robust and reliable choice for users looking for a dependable uninterruptible power supply. With a power capacity of 2000VA/1800W, it is well-suited for powering essential equipment during outages. One of its standout features is the online double conversion technology, which ensures consistent power quality by continuously converting incoming power to DC and then back to AC. This makes it ideal for environments where power reliability is critical.

The UPS is designed in a versatile 2U rack/tower format, granting flexibility in installation and saving valuable space. Its energy efficiency is boosted by the Energy Star 2.0 certification, which means it operates efficiently even in eco-mode, making it a cost-effective solution over time. Additionally, the unit includes automatic voltage regulation (AVR) to protect against voltage fluctuations, and the sine wave output provides clean power suitable for sensitive electronics. The updated firmware addresses previous fan noise issues, enhancing user experience.

However, at 58.7 pounds, the unit is relatively heavy, which could pose challenges during installation. The sealed lead-acid battery, while reliable, may require eventual replacement, which could be a downside compared to newer battery technologies like lithium-ion. The device's color graphic display with gravity sensing is a user-friendly feature, providing easy access to information and settings. The four programmable output receptacles offer versatile options for managing connected devices and optimizing battery usage.

In summary, the Vertiv Liebert GXT5 is a powerful UPS for those needing solid protection and performance for their computing devices, particularly in settings where power stability is crucial. Despite its weight and potential battery maintenance needs, its advanced features and energy efficiency make it a strong contender in the UPS market.

The Liebert GXT4 UPS offers substantial power capacity with 10000VA and 9000W, making it suitable for high-demand environments. Its online double-conversion technology ensures consistent power quality without relying heavily on the battery, which helps prolong battery life. The UPS supports both 208V and 120V outputs, adding versatility for different equipment types.

With integrated surge protection and Automatic Voltage Regulation (AVR), it provides robust defense against power disturbances, ensuring stable operation of connected devices. The inclusion of a network card enhances remote monitoring capabilities, allowing users to manage the UPS through applications like Trellis power insight or other platforms, which is a significant convenience for IT managers and professionals needing reliable oversight of their power systems. Form factor-wise, its rack mount/tower design offers flexibility in installation, accommodating various setups.

However, the unit's weight (213 pounds) and dimensions might make it challenging to handle and install without proper equipment and assistance. The hot-swappable batteries provide around five minutes of backup at full load, which is relatively short but can be extended with additional external battery cabinets if needed. This feature ensures that critical equipment remains operational during short outages. The Liebert GXT4 UPS is a powerful and versatile option for environments with significant power protection needs, but users should be prepared for its substantial size and weight when planning installation.
