10 Best Battery Backups 2025 in the United States

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 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 Liebert GXT4 UPS (GXT4-6000RT208) is a reliable uninterruptible power supply designed for critical equipment. With a power capacity of 6000VA/4800W, it offers robust protection against power outages. The online double-conversion technology ensures clean and stable power, extending battery life by conditioning the power supply without frequently using the battery. This UPS includes an automatic voltage regulation (AVR) feature, which helps maintain a consistent voltage level to your devices, further protecting them from power fluctuations.

Equipped with a network card, it allows remote monitoring through the Trellis power insight application, which is convenient for managing power usage and status updates. The battery runtime at full load is up to 5 minutes, and you can extend this by adding up to six external battery cabinets. Hot-swappable batteries mean you can replace them without shutting down the entire system, ensuring continuous operation. The unit comes with essential accessories like a rack-mounting rail kit, tower support stands, and cables for easy setup.

However, it's important to note that this model is now obsolete and has been replaced by the GXT5-6000MVRT4UXLN. The primary downside is its weight and size, making it relatively bulky and potentially challenging to install without adequate space. This UPS is suited for professional environments where uptime is critical, such as data centers or high-availability server rooms. With its high capacity and advanced features, it might be overkill for typical home use.
