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 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.

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.
