10 Best Ups Power Backup 2025 in the United States

The GOLDENMATE 1000VA/800W Lithium UPS Battery Backup is a reliable power backup solution with several notable strengths. Equipped with a lithium iron phosphate battery, this UPS offers a long lifespan of over 10 years and more than 5000 charge cycles, making it a cost-effective choice with reduced maintenance needs. The power capacity of 1000VA/800W is suitable for protecting computers, workstations, and network devices from power interruptions and fluctuations. With eight NEMA 5-15P outlets, it provides ample connectivity options for multiple devices, all with surge protection and battery backup.

The built-in Automatic Voltage Regulation (AVR) ensures stable power output, addressing issues like voltage drops and surges. The real-time monitoring via an intelligent LCD panel adds to its usability, offering detailed battery and power condition information. Safety features, including certifications from UL and TUV, along with a built-in Battery Management System (BMS), enhance its reliability.

However, some users might find the unit's weight of 12.13 pounds and dimensions slightly bulky for small spaces. Additionally, while the noise level of the cooling fan is kept below 50 dB, it may still be noticeable in quiet environments. The absence of specific mention of communication ports like USB or Ethernet might be a drawback for users needing remote monitoring capabilities. Despite these minor issues, the GOLDENMATE UPS stands out as a durable and efficient solution for most home and office power backup needs.

The Vertiv Liebert PSI5 Lithium Ion UPS is a reliable power backup solution with a substantial power capacity of 1500VA/1350W, making it suitable for protecting critical equipment against power disturbances. Its lithium-ion batteries are a standout feature, offering twice the lifespan of traditional VRLA batteries and reducing the need for frequent replacements, which can lower the cost of ownership. The UPS also features a decent battery runtime, providing up to 7.5 minutes at full load and 17.7 minutes at half load, giving users adequate time to save work and shut down devices properly during an outage.

Additionally, the batteries recharge quickly, reaching full capacity within 2 hours, ensuring minimal downtime between uses. It includes three programmable outlets and a rotating LCD display for easy monitoring and management. The Automatic Voltage Regulation (AVR) helps maintain stable voltage levels, protecting connected devices from power fluctuations. However, there are a few drawbacks to consider. The UPS is relatively heavy at 41.6 pounds, which might be cumbersome for some users. It also has a limited number of outlets, which might not be sufficient for setups requiring multiple connections.

Despite these minor issues, the Vertiv Liebert PSI5 offers robust features, a good warranty, and reliable performance, making it a solid choice for users needing dependable power backup for their equipment.

The APC UPS 1500VA Sine Wave UPS Battery Backup (BR1500MS2) is a solid choice for those looking for reliable power backup, especially for high-end electronics like computers. With a power capacity of 1500VA/900W, it provides substantial backup power. It features 10 outlets, where 6 outlets offer both surge protection and battery backup, while the remaining 4 provide only surge protection. This should be ample for most small office or home setups.

The inclusion of Automatic Voltage Regulation (AVR) helps maintain a consistent voltage level, protecting your devices from power fluctuations, which is a significant advantage. Additionally, the sine wave output is ideal for sensitive electronics, ensuring smooth and reliable power delivery. The UPS is equipped with two USB charger ports (one USB-C and one Type-A), allowing you to charge devices conveniently. The replaceable battery feature means you can prolong the life of the unit by swapping out the battery when needed, though the replacement battery is sold separately.

On the downside, the UPS is quite heavy at 27.6 pounds, which might be cumbersome if you need to move it frequently.
