10 Best PC battery backups 2025 in the United States

The Vertiv Liebert GXT5 UPS is a strong choice if you need reliable, high-capacity battery backup for sensitive or critical equipment. It offers 1500VA/1350W power capacity, which can support multiple devices and provides a good balance of power for most small office or home setups. Its online double conversion design ensures clean and stable power, protecting your PC and electronics from outages and voltage fluctuations. This model features four programmable outlets, letting you manage connected devices efficiently and extend battery life when needed.

The LCD display with color graphics makes it easy to monitor power status, and the gravity sensing feature means the screen adjusts automatically for easier reading. It also includes surge protection and automatic voltage regulation (AVR) to handle power spikes and maintain consistent voltage, which is important for sensitive hardware. The UPS is Energy Star 2.0 certified, meaning it is designed for energy efficiency, especially in eco-mode, helping reduce electricity use.

On the downside, it uses sealed lead-acid batteries, which are heavier and require maintenance over time compared to newer battery types. The unit itself is quite heavy (over 57 pounds) and large (2U rack/tower form factor), so it’s better suited for stationary setups rather than portable use. It features a good power factor of 0.9, making it efficient for its class. This UPS is best suited for users looking for a robust, energy-efficient backup solution for critical electronics in office or server room environments.

The Eaton International 5S UPS is a reliable uninterruptible power supply designed to protect your PC and other electronics during power outages and surges. It offers a power capacity of 1500 VA (900 Watts), which is sufficient to support multiple devices like a desktop computer and peripherals for a limited time. With 8 IEC C13 outlets, it provides plenty of connection points, making it useful if you have several pieces of equipment to protect.

The lithium-ion battery helps keep the unit lightweight at 26 pounds, which is relatively portable for a UPS of this size. Its slim form factor (about 1.4 inches high) allows for easy placement in tight spaces such as under a desk or in a server rack. Surge protection and automatic voltage regulation (AVR) are standard features in this model line, offering stable power delivery and safeguarding your devices from voltage spikes.

This UPS is a solid choice for home or small office users who need dependable backup power and multiple outlets but may not be ideal if you require long battery runtime or more advanced monitoring features. Note that the IEC connectors may require adapters depending on your region or device plugs.

The APC Back-UPS Pro Gaming UPS is a solid choice for gamers looking to protect their gaming consoles and PC setups. With a power capacity of 1500VA/900W, it offers ample backup power to keep your devices running during outages. The interactive LCD display with the Reactor Circle feature provides real-time status updates and colorful alerts for surges and power dips, which can be particularly useful in a gaming environment. The customizable RGB ambient LED lighting adds a nice touch for those who want their UPS to match their gaming setup aesthetics.

There are 10 outlets total, with 6 providing battery backup and 4 offering surge protection only, plus it includes 3 USB charging ports (2 Type-A and 1 Type-C), covering a wide range of connectivity needs. The Automatic Voltage Regulation (AVR) feature ensures a stable voltage supply, and the unit is compatible with Active PFC, making it a versatile option. It also includes surge-protected dataline and gold-plated coaxial ports, along with a 6-foot power cord and a user-replaceable battery.

However, at 30.9 pounds, it is quite heavy and not very portable. The plastic build might not appeal to those looking for a more robust material. Additionally, the requirement to purchase the battery separately could be seen as an inconvenience. It comes with a 3-year warranty and a $250,000 Equipment Protection Policy, providing peace of mind for users. This UPS is best suited for gamers who need reliable power backup and want extra features like customizable lighting and an informative display.
