10 Best Pc Battery Backups 2025 in the United States

The Amazon Basics Standby UPS Battery Backup offers a solid option for those looking to protect their electronics during power outages. With a power capacity of 600VA and 360W, it’s well-suited for desktop computers, home networks, and entertainment systems, making it a great choice for home users and small office setups. One of its standout features is the inclusion of 8 outlets, with 4 dedicated to surge protection and 4 for battery backup, allowing multiple devices to remain powered during outages.

The compact design is another plus, as it can easily fit into various spaces without taking up too much room. Its 5-foot cord with a right-angle plug adds convenience for placement. Additionally, it includes power management software that can help monitor and manage connected devices, enhancing usability.

However, there are a few drawbacks to consider. The maximum power capacity means it’s important to keep the total device consumption under 80% of the rated capacity to ensure optimal performance. This limits the number of high-powered devices you can connect simultaneously. Additionally, while it’s effective for short outages, users should not expect it to power devices for an extended time, as its runtime will vary significantly based on the load.

The Vertiv Liebert PSI5 Lithium-Ion UPS offers an impressive power capacity of 3000VA/2700W, making it highly suitable for those needing substantial backup power. Its lithium-ion batteries are a standout feature, boasting a lifespan up to three times longer than traditional VRLA batteries, which can provide peace of mind and lower long-term maintenance costs.

The compact and short-depth chassis design makes it a good fit for 2-Post racks and wall-mount racks, and its rack/tower convertible form factor adds flexibility for various installation scenarios. This unit also comes with a five-year warranty, covering both the UPS and the batteries, enhancing its reliability and value proposition.

However, the product does have some drawbacks. It is relatively heavy at 68 pounds, which may require careful handling and installation. Additionally, with dimensions of 22.4 x 26.4 x 11.1 inches, it may take up a considerable amount of space depending on the setup. The Vertiv Liebert PSI5 Lithium-Ion UPS is a robust and flexible choice for users with high power needs and non-standard installation spaces, but its weight and size could be potential concerns.

The CyberPower PR1500LCD Smart App Sinewave UPS System is a solid choice for anyone looking for a reliable uninterruptible power supply, especially in office environments. With a power capacity of 1500VA/1500W, it provides ample backup for essential devices like servers, network equipment, and telecom systems. One of its standout features is the eight outlets, which offer both battery backup and surge protection, allowing multiple devices to be safeguarded at once.

The built-in Automatic Voltage Regulation (AVR) is also a significant advantage, as it helps manage and correct minor voltage fluctuations without relying on battery power, ultimately extending the lifespan of the battery. Plus, the multifunction LCD panel gives users immediate information on battery status and power conditions, which is very helpful for monitoring.

On the downside, while the unit is fairly compact for its capacity, it may still take up a bit of space in smaller setups. Additionally, the optional remote monitoring card (RMCARD205) might add to the cost if you need that feature. The unit's weight at around 3.38 pounds might also be cumbersome for some users when relocating. The three-year warranty, which includes the battery, along with a generous connected equipment guarantee, adds extra peace of mind for users.
