10 Best Ups Backups 2026 in the United States

The EF ECOFLOW DELTA Pro with 2 Extra Batteries is a powerful and flexible portable power station designed for home backup, camping, and emergencies. It offers a very high power capacity of up to 10.8kWh when expanded, which is enough to run many heavy-duty home appliances and tools. The unit can handle a strong output of 3600 watts (expandable to 4500W with X-Boost), making it suitable for reliable backup power during outages. One of its biggest advantages is the fast charging ability—fully recharging in under 2 hours using a 240V outlet, or with solar panels in a few hours—giving you plenty of options to keep it powered up. It also supports multiple charging methods (EV charger, solar, car, generator), making it very versatile on the go.

The smart app and home panel let you monitor usage and customize how you draw power, which is helpful for saving on electricity bills and managing energy. On the downside, the DELTA Pro is quite heavy at 330 pounds, so it’s not very portable for casual use or carrying around easily. It’s also more expensive and complex than smaller UPS units, so it’s best suited for users who want a serious all-in-one backup system rather than a simple power strip with battery backup.

For those needing a large-capacity, expandable, and smart-managed power backup for home or outdoor adventures, the DELTA Pro is a solid choice. However, it is less ideal if you prefer something lightweight or more basic.

The EF ECOFLOW DELTA Pro is a powerful portable power station designed mainly for home backup, outdoor activities, and emergencies. It offers a strong power capacity starting at 3.6kWh that can be doubled to 7.2kWh with an extra battery, making it capable of running many heavy-duty devices quietly and without fumes. Its 3600W output, expandable to 4500W with X-Boost, means it can handle almost all household equipment during outages.

The unit supports multiple charging options, including very fast wall charging, solar panels, car, and EV stations, providing flexibility depending on your situation. It features 120V outlets along with surge protection and a clean power output to keep your devices safe. The smart app control lets you monitor battery life, temperature, and customize settings remotely, which is convenient for managing energy use.

The DELTA Pro weighs 183 pounds and has a sizable form factor, so it is less portable for casual use or light camping. Its price point and complexity are more suited for users needing serious backup power rather than occasional use. This unit functions well as a reliable, expandable home backup and solar generator but may be excessive for those requiring only a small, lightweight UPS for minor power needs.

The Amazon Basics UPS Battery Backup offers solid protection for home or small office electronics with a power capacity of 1500VA/900W, which is sufficient for most personal computers, routers, and entertainment devices. It includes 10 outlets—five with surge protection and five that also provide battery backup—giving you flexibility depending on what you want to keep running during a power outage. Its line-interactive design includes Automatic Voltage Regulation (AVR), which helps stabilize voltage without draining the battery, ensuring your devices run smoothly during minor power fluctuations.

The unit has a compact mini tower form factor, making it easy to fit under a desk or in a media center. The battery runtime will depend on the load but users are advised to keep connected devices under 80% of the capacity for best performance. It also offers surge protection to safeguard against power spikes. While it doesn’t have advanced connectivity features like network monitoring out of the box, power management software can be downloaded if you want to monitor activity on your computer.

Weighing 25 pounds, it is somewhat heavy, which is typical for UPS units with lead acid batteries, like this model uses. This UPS is a practical choice if you need reliable backup power to prevent data loss from outages and want a straightforward setup without extra bells and whistles. If longer battery runtime or more advanced management options are required, exploring higher-end models may be beneficial.
