Power Capacity (VA/W)
The system delivers robust power output capable of running nearly all home appliances, including heavy loads like dryers and heaters.
Battery Runtime
Expandable battery capacity up to 48kWh offers flexible backup power lasting several days depending on usage.
Number of Outlets
The 18 available outlets allow powering multiple devices simultaneously without hassle.

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.

Power Capacity (VA/W)
While it doesn’t deliver pure sine wave output, this doesn’t impact common AC adapter-powered devices that are the primary intended loads.
Battery Runtime
This UPS reliably keeps essential home devices like routers and VoIP phones running through brief power interruptions, ensuring uninterrupted connectivity during critical tasks.

The Amazon Basics UPS Battery Backup offers 400VA/255W power capacity, which suits basic home devices like routers, smart home gadgets, and entertainment systems. It provides a short but useful battery runtime: about 6 minutes at half load and 1.5 minutes at full load. This is enough to keep your devices running briefly during outages or safely shut them down. The UPS has 6 outlets—half with battery backup and surge protection, and half with surge protection only—giving you some flexibility in how you connect your equipment. Its compact size makes it easy to fit on a desk or shelf without taking much space.

Surge protection helps shield your electronics from sudden voltage spikes, though this model uses a standby UPS design rather than the more advanced line-interactive Automatic Voltage Regulation (AVR), which means it might not smooth out voltage fluctuations as effectively. Connectivity is limited to simple power management software downloadable from Amazon’s site, without USB or network connections found in more advanced models. The UPS uses a lead-acid battery, which is reliable but heavier and bulkier compared to newer battery types.

If you have basic power backup needs for small home devices and want an affordable, compact unit, this UPS is a good fit. For those requiring longer runtime, more advanced voltage regulation, or extensive device monitoring, considering a higher-end model would be advisable.

Buying Guide for the Best Ups Backups

When choosing a UPS (Uninterruptible Power Supply) backup, it's important to understand that this device is designed to provide emergency power to your electronics in the event of a power outage. The right UPS can protect your equipment from data loss, hardware damage, and downtime. To make an informed decision, you need to consider several key specifications that will determine the suitability of a UPS for your needs.
Power Capacity (VA/W)Power capacity, measured in Volt-Amps (VA) and Watts (W), indicates the maximum load a UPS can handle. This is crucial because it determines how many devices you can connect and how much power they can draw. To navigate this, calculate the total wattage of all devices you plan to connect. For home use, a UPS with a capacity of 600-1000 VA might suffice, while for office setups, you might need 1500 VA or more. Choose a UPS with a capacity that exceeds your total wattage by at least 20% to ensure reliable performance.
Battery RuntimeBattery runtime refers to how long the UPS can power your devices during an outage. This is important for ensuring you have enough time to save work and shut down equipment properly. Runtime can vary from a few minutes to several hours. For basic needs, a UPS with 5-10 minutes of runtime might be enough, but for critical systems, you may need 30 minutes or more. Consider your typical power outage duration and the importance of your devices to determine the right runtime for you.
Number of OutletsThe number of outlets on a UPS determines how many devices you can connect. This is important for ensuring all your essential equipment is protected. Outlets can be divided into battery-backed and surge-only. For a home office, 4-6 battery-backed outlets might be sufficient, while larger setups may require 8 or more. Count the devices you need to protect and ensure the UPS has enough outlets to accommodate them.
Form FactorForm factor refers to the physical size and shape of the UPS. This is important for ensuring it fits in your intended space. UPS units come in various forms, such as tower, rack-mounted, and compact. For home use, a compact or tower UPS might be ideal, while for server rooms, a rack-mounted unit could be more appropriate. Consider where you will place the UPS and choose a form factor that fits comfortably in that space.
Surge ProtectionSurge protection safeguards your devices from voltage spikes, which can cause damage. This is important for protecting sensitive electronics. Look for a UPS with a high joule rating, which indicates better protection. For basic protection, 200-400 joules might be enough, but for more sensitive equipment, look for 600 joules or higher. Assess the sensitivity of your devices and choose a UPS with adequate surge protection.
Automatic Voltage Regulation (AVR)Automatic Voltage Regulation (AVR) stabilizes the voltage supplied to your devices, preventing damage from voltage fluctuations. This is important for maintaining consistent power quality. AVR is particularly useful in areas with unstable power supply. If you experience frequent voltage fluctuations, choose a UPS with AVR to ensure your devices receive stable power.
Connectivity and MonitoringConnectivity and monitoring features allow you to manage and monitor your UPS remotely. This is important for ensuring your UPS is functioning correctly and for receiving alerts about power issues. Look for UPS units with USB or network connectivity and compatible software. For basic needs, simple USB connectivity might suffice, but for more advanced monitoring, network connectivity and comprehensive software are beneficial. Consider how much control and information you need about your UPS to choose the right connectivity options.
