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 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.

The Eaton 5P rackmount Compact 1500VA UPS is designed to provide reliable power backup for small to medium-sized setups. With a power capacity of 1440 VA and 1100 W, it offers a solid performance for supporting critical devices. The unit includes 10 NEMA 5-15R outlets, which allows you to connect multiple devices.

The UPS is built with lead-acid batteries, ensuring steady power during outages. Its 2U rackmount form factor is compact, measuring 3.4 inches in height, 17.3 inches in width, and 16 inches in depth, making it suitable for various rack configurations. Weighing approximately 41 pounds, it is relatively easy to handle for an installation of this type.

Additional features include a quick start guide, USB cable, RS-232 serial cable, and a multi-purpose rail kit, which simplify setup and connectivity. It is also environmentally friendly with RoHS certification, which is a plus for eco-conscious users. This UPS is best suited for users needing a reliable power backup solution for network and server equipment in a compact rackmount form.
