10 Best Battery Backups 2025 in the United States

The Amazon Basics Standby UPS Battery Backup offers a power capacity of 600VA/360W, which makes it suitable for desktop computers, home networks, IoT devices, and home entertainment systems. It comes with 8 outlets in total – 4 surge-protected and 4 that are both surge-protected and battery-backed. This ensures your devices remain powered during short outages and have enough time to shut down properly during longer ones.

Its compact design allows easy integration into any home or office setup, and the 5-foot cord with a right-angle plug provides flexibility in placement. One downside is that you need to ensure the total power consumption of the devices connected to the battery backup outlets stays below 80% of the unit's capacity for optimal performance.

Additionally, while it does offer automatic voltage regulation (AVR), it may not be suitable for high-powered equipment due to its limited wattage. The lack of an LCD display may also be a drawback for users who prefer real-time monitoring of UPS status. Despite these limitations, this UPS stands out for its practicality in protecting essential electronic devices from power surges and outages.

The Amazon Basics Standby UPS Battery Backup is a compact and efficient solution for protecting essential electronics during power disturbances. With a power capacity of 400VA and 255W, it is well-suited for home networks, IoT devices, and home entertainment systems. One of its main strengths is the six outlets provided—three for surge protection and three that also offer battery backup, allowing you to safeguard multiple devices simultaneously.

In terms of design, the small form factor means it can fit easily into various spaces without being obtrusive. The 5-foot cord with a right angle and offset plug is a thoughtful touch, making installation more versatile. The availability of power management software for download is a bonus, providing users with additional tools to monitor their energy use.

However, there are some limitations to consider. The total load should remain under 80% of the unit's rated capacity for optimal performance, which could restrict its use if you have multiple devices with high power demands. Also, while it provides essential protection during short outages, the runtime may not be sufficient for extended power failures, so it's not ideal for users needing long-term backup.

The Vertiv Liebert GXT5 UPS is a solid choice if you need a reliable and strong battery backup system, especially for critical equipment. It offers a high capacity of 3000VA (2700W), which means it can support multiple devices with a good amount of power. One standout feature is its four individually programmable output ports, allowing you to control and manage connected devices efficiently to save battery life. The device has a user-friendly color LCD with a gravity sensor, making it easy to monitor the status at a glance. It’s also Energy Star 2.0 certified, so it operates efficiently, which helps reduce electricity costs.

The safety features are robust, thanks to its online double conversion technology and lead acid battery type, ensuring clean and stable power delivery. On the downside, it’s quite heavy at over 77 pounds and fairly large, so it might not be the best fit if space or portability is a concern.

This UPS is well-suited for small to medium-sized business setups or home offices where reliable and continuous power is essential, but it might be more than needed for casual or light use.
