EcoFlow Delta 2 Review

EcoFlow Delta 2 Review

Are you looking for a portable power station that can provide enough power to run your essential devices and appliances during power outages or while camping? If yes, then the EcoFlow Delta 2 might be just what you need. In this EcoFlow Delta 2 Review, we will take a closer look at this powerful and versatile power station and explore its features, specifications, and performance.

The Delta 2 is the successor to the popular EcoFlow Delta and comes with several upgrades and improvements, including a more powerful inverter, a faster charging system, and a more robust and durable design.

EcoFlow Delta 2 Charging

How much power does the EcoFlow Delta 2 produce?

1800 watts of continuous power and 2400 watts of surge power

The EcoFlow Delta 2 is a powerful portable power station that produces up to 1800 watts of continuous power and 2400 watts of surge power thanks to its X-Boost technology. It has a 1024Wh capacity lithium-ion battery that can power multiple devices at once. 

EcoFlow's X-Boost technology is a feature that's available in some of their portable power stations, including the EcoFlow Delta 2. This technology allows the Delta 2 to power devices that require higher wattage than its standard output.

The X-Boost feature is particularly useful for powering high-wattage devices such as power tools, air conditioners, and electric kettles. It also allows you to power multiple devices simultaneously without any risk of overload.

One of the benefits of X-Boost technology is that it enables the Delta 2 to start up devices that have high start-up power requirements. For example, an air conditioner may require up to 2400 watts of power to start, but once it's running, it only needs around 1000 watts. With X-Boost, the Delta 2 can provide the necessary power to start the air conditioner and then reduce its output to the required level, thus preserving its battery life.

Flexibility with multiple output choices

The Delta 2 has a variety of output options including AC, DC, USB-A, USB-C, and car power ports. This allows you to power a wide range of devices such as laptops, smartphones, TVs, refrigerators, and power tools.

The four UK socket plugs can be used simultaneously, allowing you to power multiple devices at the same time. This is particularly useful if you're using the Delta 2 for outdoor activities such as camping, where you may need to power multiple appliances or devices.

On the other side of the battery pack are the USB ports with two USB-A, two fast-charge USB-A and dual USB-C 100W PD ports.

Solar Recharging

Solar recharging

Recharge the Delta 2 in 3-6 hours

The EcoFlow Delta 2 is a portable power station that can be recharged using solar panels. This makes it an ideal power source for outdoor adventures, camping trips, and emergency backup power.

To recharge the Delta 2 using solar power, you will need to connect it to a compatible solar panel. EcoFlow offers its own line of solar panels, including the 110W Solar Panel and the 400W Solar Panel. These panels can be connected to the Delta 2 using the included MC4 to XT60 cable.

The Delta 2 can also be charged using third-party solar panels, as long as they have a compatible output voltage and current. However, it is important to note that using non-EcoFlow solar panels may affect the charging speed and efficiency of the Delta 2.

When using solar panels to recharge the Delta 2, it is important to place the panels in direct sunlight for optimal charging. The charging time will depend on the wattage of the solar panel and the amount of sunlight available. For example, the EcoFlow 400W Solar Panel can fully recharge the Delta 2 in 3-6 hours, depending on the weather conditions.

Super Fast charging

0-80% in 50 mins

The Delta 2's AC charging speed is up to 1100W, which means it can be fully charged in under 2 hours using a standard wall outlet. This is significantly faster than other portable power stations on the market, which can take several hours to fully charge. Using the plug socket you can charge to 80% in just 50mins or to 100% in 80 minutes. 

Weight & Dimensions

The Delta 2 weighs just 12 kg, making it one of the lightest portable power stations on the market . This is thanks to its use of high-density lithium-ion battery cells, which are lighter and more compact than other types of batteries.

In terms of dimensions, the Delta 2 measures:

15.7 x 8.3 x 11 in / 400 x 211 x 281 mm

This compact size makes it easy to store in small spaces, such as a closet or a car trunk.

Long Battery Life thanks to LiFePO4

3000+ cycles until 80% of it's original storage capacity

The EcoFlow Delta 2 uses a lithium iron phosphate (LiFePO4) battery, also known as LFP. LiFePO4 batteries are a type of rechargeable battery that have become increasingly popular in recent years due to their safety, high energy density, and long life cycle.

Compared to other types of lithium-ion batteries, such as lithium cobalt oxide (LiCoO2) or lithium manganese oxide (LiMn2O4), LiFePO4 batteries are considered to be safer and more stable. This is because they are less prone to thermal runaway and other safety hazards that can occur with other types of lithium-ion batteries.

One of the key advantages of LiFePO4 batteries is their long life cycle. The EcoFlow Delta 2's battery is rated for 3000+ cycles until the battery becomes 80% of it's original storage capacity, which is significantly more than other types of lithium-ion batteries. A cycle is defined as one complete charge and discharge cycle of the battery.


The EcoFlow Delta 2 is a powerful and versatile portable power station that can provide enough power to run most appliances and devices during power outages or while camping. With its massive battery capacity, powerful inverter, and multiple charging options, it's one of the most reliable and efficient portable power stations on the market.

However, it's also expensive and heavy, which may not be suitable for everyone. Overall, the EcoFlow Delta 2 is an excellent choice for those who need a reliable and powerful portable power station for their outdoor activities or emergency backup power.
