10 Best Battery Backups 2025 in the United States

The Vertiv Liebert GXT5 UPS is a robust choice for those needing reliable battery backup, particularly in sensitive environments like servers and networking. With a power capacity of 2000VA and 1800W, it provides ample support for essential devices without risking overload. Its online double conversion technology ensures a consistent sine wave output, which is crucial for maintaining the health of connected electronics.

One of its standout features is the colored LCD display, which offers a user-friendly interface for monitoring the UPS's status and battery life. Its programmable outlets allow for tailored management of connected devices, optimizing battery use based on your needs. The unit is also Energy Star certified, demonstrating higher efficiency, especially when running in eco-mode, which can contribute to lower energy costs over time.

The UPS is quite heavy at 58.7 pounds, making it less portable if you need to move it frequently. While it excels in providing power, the sealed lead-acid battery may require eventual replacement, which can be an added cost. Additionally, while the updated firmware reduces fan noise, some users may still find the unit’s noise level higher than desired in quiet environments. The Liebert GXT5 is ideal for anyone who prioritizes high power capacity and reliability, such as small businesses, data centers, or home offices with critical equipment. However, if you're looking for a lightweight or extremely quiet solution, you might want to explore other options.

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 Schneider OffGrid Portable Power Station 300W is a versatile and compact power solution ideal for camping, RV trips, and home backup. With a 332Wh lithium-ion battery, this portable power station can recharge via multiple sources: AC wall outlet, car port, USB-C, and solar panels (sold separately). It offers a good balance of portability and power, weighing just 8 pounds and measuring 8.8 x 6.4 x 6 inches. This makes it easy to carry around while still packing enough juice to power up various devices.

You can charge up to 8 devices at once with a maximum output of 531W. It features 2 AC outlets, 3 USB-A ports, a 60W USB-C PD port, a 120W car cigarette DC output port, and a wireless charging pad. For added convenience, there's a large ambient LED light with an SOS signal feature, useful in emergencies. The LCD display provides clear information about the power station's status, and the 2-year warranty adds peace of mind.

However, its battery runtime of only 1 hour under full load might be a limitation for those needing longer backup times. Additionally, while it supports 300W output with a 600W surge, heavy-duty appliances might not be compatible. For those who need a lightweight and flexible power solution for occasional use, particularly in outdoor settings, the Schneider OffGrid Portable Power Station 300W is a solid choice.
