10 Best Ups Uninterrupted Power Supplies 2025 in the United States

The Amazon Basics UPS Battery Backup & Surge Protector offers a compact and efficient solution for ensuring uninterrupted power to your devices during outages and power surges. With an 800VA/450W power capacity, it's suitable for desktop computers, home networks, IoT devices, and home entertainment systems. It features a total of 12 outlets, with six dedicated to surge protection and six providing both surge protection and battery backup, allowing you to connect multiple devices simultaneously.

The small form factor makes it easy to integrate into any home or office environment, and the 5-foot cord with a right-angle plug enhances user convenience in tight spaces. However, it operates as a standby UPS, which might not provide the purest sine wave output compared to higher-end models, potentially affecting the performance of sensitive electronics. Additionally, it lacks Automatic Voltage Regulation (AVR), which means it may not handle voltage fluctuations as efficiently as AVR-equipped models.

While it offers a reliable battery runtime for short outages, you'll need to ensure your connected devices don't exceed 80% of the unit's rated capacity for optimal performance. The downloadable power management software can help monitor the UPS's status, although the lack of communication ports means remote management is limited. This UPS is best suited for users with moderate power needs looking for a cost-effective and space-saving solution.

The Vertiv Liebert GXT5 UPS is a robust 2000VA/1800W power supply unit designed to provide reliable power backup with its online double conversion technology, making it ideal for environments where power consistency is critical. Its power capacity is well-suited for small to medium-sized setups, and the included automatic voltage regulation helps maintain steady voltage levels. With 2U rack/tower form factor flexibility, it's versatile for different installation needs.

One of its strong points is the high power factor of 0.9, which ensures efficient power usage. The UPS outputs a pure sine wave, which is crucial for sensitive electronics, reducing the risk of damage or performance issues. The energy efficiency is notable, as it's Energy Star 2.0 certified, indicating it can run cost-effectively both in standard and eco modes.

The unit features a user-friendly interface highlighted by a colored LCD with gravity sensing, enhancing usability and providing clear information at a glance. Moreover, it offers four programmable outlets for better control over device power management, optimizing battery life during outages.

However, it is relatively heavy at 58.7 pounds, which might pose challenges in terms of mobility or installation for some users. The sealed lead-acid battery, while reliable, might not have the longevity or eco-friendliness of more modern battery types like lithium-ion.

The Vertiv Liebert GXT5 is a solid choice for users seeking a balance between high performance and energy efficiency in an uninterrupted power supply, especially in environments where equipment sensitivity and uptime are priorities.

The Amazon Basics UPS Battery Backup & Surge Protector offers a 400VA/255W power capacity, making it suitable for small home networks, IoT devices, and home entertainment systems. With 6 outlets in total, it includes 3 surge-protected outlets and 3 outlets that provide both battery backup and surge protection. This ensures that your devices are protected during power surges and can stay powered on during short outages, giving you enough time to shut them down properly during longer outages.

The compact size (7.24 x 4.33 x 3.22 inches) allows it to fit easily into any home or office setup, and the 5-foot cord with a right-angle plug adds convenience for various placement options. One notable feature is the Automatic Voltage Regulation (AVR), which helps maintain a steady voltage, preventing damage to your devices from voltage fluctuations.

The device also supports communication through downloadable power management software, which can be useful for monitoring and managing power usage. It is essential to keep the load below 80% of the rated capacity to ensure optimal performance. This UPS is a solid choice for users needing basic power protection for smaller devices.
