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 Vertiv Liebert GXT5 UPS is a strong choice if you need reliable, high-capacity battery backup for sensitive or critical equipment. It offers 1500VA/1350W power capacity, which can support multiple devices and provides a good balance of power for most small office or home setups. Its online double conversion design ensures clean and stable power, protecting your PC and electronics from outages and voltage fluctuations. This model features four programmable outlets, letting you manage connected devices efficiently and extend battery life when needed.

The LCD display with color graphics makes it easy to monitor power status, and the gravity sensing feature means the screen adjusts automatically for easier reading. It also includes surge protection and automatic voltage regulation (AVR) to handle power spikes and maintain consistent voltage, which is important for sensitive hardware. The UPS is Energy Star 2.0 certified, meaning it is designed for energy efficiency, especially in eco-mode, helping reduce electricity use.

On the downside, it uses sealed lead-acid batteries, which are heavier and require maintenance over time compared to newer battery types. The unit itself is quite heavy (over 57 pounds) and large (2U rack/tower form factor), so it’s better suited for stationary setups rather than portable use. It features a good power factor of 0.9, making it efficient for its class. This UPS is best suited for users looking for a robust, energy-efficient backup solution for critical electronics in office or server room environments.
