First Impression

Not a lot has changed when you compare both models. DELTA 2 seems to be quite bigger than its predecessor DELTA to the naked eye.  EcoFlow seems to have retained the original design and color combination. They both look identical except for the ports.

Input MQTT and AC Ports along with an overload switch at the back of DELTA are moved towards the side of DELTA 2. This is a good change as you need not worry about handling the wires if there is a tiny space.

The above picture shows the side view of Delta where you can find three ports that are now being moved to the back in Delta 2 (see picture below)

In addition to it, you can now see a new battery extender port at the back of DELTA 2 allowing you to connect to an external battery. Let us see more about this in the next section.

The traditional 60W USB-C ports are upgraded to 100W USB-C ports which is a good thing. A new on/off switch has been added to the cigarette and dc ports for better control.

Also, EcoFlow seems to have tweaked the power-on button to a gold color for clear visibility.

Delta vs Delta 2

Battery Capacity and Power

Not a lot has changed when it comes to batteries. But there are some improvements that can be seen. Both DELTA and DELTA 2 have a power capacity of 1800W. But DELTA 2 can power devices up to 2200W, thanks to X-boost technology.

When it comes to battery capacity, DELTA 2 has a slightly lesser capacity(1024Wh) which reduces the run time of electrical machines. To counter this, EcoFlow has created an ecosystem, where you can connect additional batteries of Delta 2 (+1kWh)  or Delta Max Battery (+2kWh) via XT150 cable(DC cable). These batteries come with an additional cost. Using this you can boost your DELTA 2 capacity to 2kWh or 3kWh.

Charging

EcoFlow is known for fast charging. And this continues with DELTA 2 as well.

Here is a comparison of DELTA and DELTA 2 charge times.

EcoFlow Delta EcoFlow Delta 2
 0 – 80% 60 mins 50 mins
80 – 100% 96 mins 80 mins
Life Cycle  800+ cycles to 80% capacity (NCM Battery) 3000+ cycles to 80% capacity (LFP Battery)

Also, the charging cycles have significantly increased, thanks to its LPF battery. It has nearly 3x more life and definitely long-lasting than DELTA.

With DELTA 2, you are now able to connect your smartphone to the power station where you can control many options and also get various information such as input power, output power, charge information, etc. For detailed app features, refer to the manual here.

Delta vs Delta 2: Which one to consider?

It is a no-brainer to get Delta 2 over the previous model mainly because of the feature updates and options to expand the storage over time.

If you are wondering about the ~240Wh battery difference, I suggest not to worry about it, it does not make a dent in usage.

If I am buying one today, I will definitely get the Delta 2
