Ecoflow recently released DELTA 2 MR300 portable power station which is a successor to their most popular Delta 1300 series. There are many similarities and even more differences. In this comparison, let us dive deep into it and see which is a better and worthier buy.
So let us try to understand the key upgrades from DELTA to DELTA 2 and see if it is a worthy successor.
The models being compared are as follows:

At a glance,
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)
Delta 2 Input ports moved to side
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.
Delta 2 Expandable Battery System
| Ecoflow Delta | EcoFlow Delta 2 | |
| Power | 1800W | 1800W (X-Boost upto 2200W) |
| Battery capacity | 1260Wh | 1024Wh |
| Battery Life Cycle | 800+ cycles to 80% capacity (NCM Battery) | 3000+ cycles to 80% capacity (LFP Battery) |
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 |
| Solar Panel Capacity | 400W | 500W |
| Optional Accessories | Ecoflow Solar Panels (400W, 220W, 160W and 110W) | D2 Smart Extra Battery
Ecoflow Solar Panels (400W, 220W, 160W and 110W) |
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
Alternative: A good alternative to Ecoflow Delta 2 is Jackery 1000 PRO

The Delta 1300 has a Surge power of 3300W, far more than the Delta 2 of 2200W
You are right, Delta 2 has a surge of 2700W which is lower than that of Delta (3300W). But EcoFlow has added X Boost technology (upto 2200W), which allows you to run higher rated powers by reducing voltage.
For many the life cycles are less important. I might get 40 years out of 800 cycles. 200 more watt hours in capacity for the oiginal is also notjing o scoff at. As far as extra batteries, they’re not cheap and useless on their own. Dlta 1300 models can be chained together similar to adding an extra battery but for much cheaper now and with more capacities. 2 Delta 1300 models connected will provide nearly 2600 watt hours in capacity. Much more than a Delta 2 with extra battery and not far from Delta 2 with Delta Max battery and or much cheaper and both nits will function fully on their own.
Valid. Thanks for your thoughts, Marc
Hi, I have the Delta unit. Can I connect another Delta unit to it with a charge cable that has 2 male inserts on either side?
Lead with the Delta 2 using LiFePO4 batteries.
