10 Best PC battery backups 2025 in the United States

The Amazon Basics UPS Battery Backup offers a 400VA/255W power capacity, making it a solid choice for protecting home networks, IoT gadgets, and entertainment devices from power outages and surges. It provides about 6 minutes of backup time at half load, which is enough to save your work or safely shut down devices during short outages. However, at full load, the backup time drops to roughly 1.5 minutes, so it's best to keep your connected devices under 80% of its capacity for reliable performance.

With 6 outlets total—3 of which provide both surge protection and battery backup, and 3 with surge protection only—it offers flexibility for connecting multiple devices. Its compact size and thoughtful plug design help it fit neatly in small spaces, ideal for home or office setups. The UPS includes surge protection to guard your electronics against unexpected voltage spikes.

A notable limitation is that it does not feature Automatic Voltage Regulation (AVR), so it might not smooth out minor voltage fluctuations as effectively as higher-end models. It also lacks an LCD display, meaning real-time updates on battery status are not available directly on the unit; monitoring requires optional software. The lead-acid battery used is common in this price range but generally results in heavier weight and a more limited lifespan compared to newer battery types. This UPS is a budget-friendly, compact solution suitable for everyday home use where moderate backup time and basic surge protection are needed, but it is not ideal for high-power devices or environments requiring detailed monitoring and voltage regulation.

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 robust battery backup designed for protecting important computer equipment and networking devices. Its 750VA/750W power capacity is suitable for small to medium setups, giving you enough runtime to safely save work and shut down devices during power outages. The online double conversion technology offers clean, stable power, which is great if you want reliable protection against surges and voltage problems. With an automatic voltage regulation (AVR) feature, it helps maintain steady voltage levels without switching to battery unnecessarily, extending battery life.

One standout feature is the colored LCD display with gravity sensing, making it easy to read vital information from different angles. The UPS also includes four programmable outlets, allowing you to manage power use and maximize battery time by controlling which devices get power during outages. It’s Energy Star 2.0 certified, so it runs efficiently, which can save electricity and reduce heat. On the downside, this model is quite heavy at 50 pounds, which might make installation or moving it a bit tricky. Being a rack/tower form factor, it fits well in server racks or on desks but might not suit every space.

This UPS is a solid choice for those seeking dependable, efficient battery backup with good power management features, especially for small offices or home setups that require clean and consistent power.
