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 CyberPower PR1500LCD Smart App Sinewave UPS System is a solid choice for anyone looking for a reliable uninterruptible power supply, especially in office environments. With a power capacity of 1500VA/1500W, it provides ample backup for essential devices like servers, network equipment, and telecom systems. One of its standout features is the eight outlets, which offer both battery backup and surge protection, allowing multiple devices to be safeguarded at once.

The built-in Automatic Voltage Regulation (AVR) is also a significant advantage, as it helps manage and correct minor voltage fluctuations without relying on battery power, ultimately extending the lifespan of the battery. Plus, the multifunction LCD panel gives users immediate information on battery status and power conditions, which is very helpful for monitoring.

On the downside, while the unit is fairly compact for its capacity, it may still take up a bit of space in smaller setups. Additionally, the optional remote monitoring card (RMCARD205) might add to the cost if you need that feature. The unit's weight at around 3.38 pounds might also be cumbersome for some users when relocating. The three-year warranty, which includes the battery, along with a generous connected equipment guarantee, adds extra peace of mind for users.

The Eaton 5SC1500 is a solid choice if you need a reliable battery backup for your high-end workstation or sensitive electronics. It offers 1440VA/1080W power capacity, which is enough to keep mid-sized setups running during outages. The built-in Automatic Voltage Regulation (AVR) helps protect your devices from power fluctuations without draining the battery, while its pure sinewave output ensures compatibility with advanced equipment that needs clean, stable power. You get eight outlets, all battery-protected, which provides good flexibility to connect multiple devices. The compact design fits well in tighter spaces, measuring about 20 inches wide and under 9 inches tall. An LCD display keeps you informed about power status and battery life, which is handy to monitor without guessing.

One of its strengths is the Advanced Battery Management technology that extends battery lifespan by up to 50%, meaning less frequent replacements. The 3-year warranty and a $150,000 connected equipment guarantee add security to your investment. On the downside, the unit is somewhat heavy at 34 pounds, making it less portable. Also, while it has decent battery runtime, exact duration depends on your load and might be limited for larger setups or longer outages.

This UPS suits professionals or home users who want dependable backup with features that enhance power quality and battery health, though it might be more than needed for very basic setups or those on a tight budget.
