10 Best Ups Backups 2025 in the United States

The EF ECOFLOW DELTA Pro is a powerful home backup battery system with a large 3600Wh battery, meaning it can store a lot of energy to keep your essential devices running during power outages. It provides up to 3600 watts of continuous power, which is enough for most household needs like lights, small appliances, and even some heavier equipment. This unit includes 6 power outlets, offering multiple connection points for your devices. Its compact tower-like form is relatively easy to place in your home.

One big plus is its ability to expand capacity up to 25kWh by adding extra batteries or solar generators, making it flexible if you want longer backup times. It also features X-BOOST technology, which helps it handle devices that need a bit more power when starting up. The DELTA Pro is designed with safety in mind, including surge protection to guard your devices from sudden electrical spikes. It supports 120V output, suitable for standard home use. ECOFLOW products typically offer app-based monitoring for ease of use.

Weighing about 99 pounds, it’s not very light, so it may need some effort to move around. This model is best for homeowners looking for a reliable, expandable backup power solution, especially if you want to integrate solar power later. It may be more than what casual users need and comes at a higher price point compared to basic UPS devices. If your primary need is simple short-term backup for small electronics, this might be more than necessary. However, for extended outages, outdoor use, or RV power, it offers robust performance with room to grow.

The EF ECOFLOW 8kWh Home Battery Backup combines two DELTA Pro 3 units linked by a 50 Amp Hub to deliver a strong 8000W AC output, which is enough to power nearly all home appliances, including heavy users like dryers and heaters. Its battery capacity starts at about 4100Wh but can be expanded up to 48kWh, offering flexible backup power for 2 to 4 days depending on usage. This makes it well suited for serious home backup needs during outages or emergencies. With 18 outlets available, it can handle multiple devices at once.

The unit supports various charging methods such as solar panels and EV chargers, letting you top up without relying on fuel. It also features a fast 10 ms switch-over, which helps avoid interruptions to sensitive electronics like servers or entertainment systems. The quiet operation (around 30 dB) is a plus if you want a backup solution that won’t disturb your household. The device is portable with handles but weighs a substantial 230 pounds, so it’s best considered semi-stationary rather than truly portable.

Another highlight is its robust battery technology (LFP cells) and IP65 rating, which adds durability and safety, backed by a 5-year warranty. On the downside, this system is relatively heavy and likely pricey, which might not fit casual or light users. Its complexity and size may also be more than needed for smaller homes or simple backup setups. While it does not explicitly mention surge protection or AVR, its design implies built-in safeguards typical for high-end home backup units. The ECOFLOW app adds convenient remote monitoring and control, which is helpful but requires some tech comfort. This product is best suited for homeowners looking for a powerful, expandable, and quiet home backup power solution who can invest in a larger system for peace of mind during extended outages.

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.
