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 Eaton Tripp Lite Series 2200VA Smart UPS is a powerful and versatile battery backup solution ideal for both home and office use. With a power capacity of 2200 Volt-Amperes (VA) and 1920 Watts, it is well-suited for protecting a range of electronic devices from power interruptions.

It comes with seven outlets, including four NEMA 5-15R and four NEMA 5-15/20R options, making it flexible for different plug types.

The device features Automatic Voltage Regulation (AVR), which corrects brownouts and overvoltages from 83V to 145V, ensuring stable power delivery without relying on the battery, thereby extending battery life and efficiency. The interactive LCD interface makes monitoring and managing the UPS straightforward, providing real-time updates on battery status and other critical metrics. Additionally, the unit can be mounted in a rack or used as a tower, offering versatility in different setups. It is also ENERGY STAR qualified, meaning it is energy-efficient.

The UPS includes USB, RS232, and EPO ports, and it has an option for a network card, which would be beneficial for network administrators. However, at 68 pounds, it is quite heavy, which may be a drawback for some users who need to move or install the unit in tight spaces. The product comes with a robust 2-year warranty that extends to 3 years upon registration, along with a $250,000 insurance for connected equipment, providing peace of mind against potential failures.
