10 Best PC battery backups 2026 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 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 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.
