DELTA 2 Overview: A Complete Competitors Comparison Guide

At EcoFlow, we strive to design innovative and sustainable portable power stations that offer safe solutions for power outages and off-grid adventures. We take pride in creating the world’s most eco-friendly power solutions that offer fast charging, renewable power generation, and more. 

We recently launched a new portable power station and are excited to share it with you! Enter — the DELTA 2. From performance to durability, we know you’ll love it as much as we do. 

Introducing the New DELTA 2 Portable Power Station

The EcoFlow DELTA 2 Portable Power Station is more than just a battery. It’s an all-in-one solution for power outages, camping trips, off-grid adventures, and more. 

With the DELTA 2, you’ll get the following perks: 

  • A secure backup solution for power outages or natural disasters
  • A safe way to run high-power appliances both indoors or outdoors
  • A portable power station that’s easy to transport and use
  • The fastest charging portable power station on the market
  • A portable power station with several charging options and expandable capacity
  • An eco-friendly and “smart” energy source
  • A 5-year warranty that offers worry-free experiences 

With this power station, you and your family will be ready for anything that comes your way! Its power supply is “smart” thanks to its Wi-Fi and Bluetooth capabilities. Users can connect it to the EcoFlow app and navigate several practical features. 

The fast charging offered by the DELTA 2 is another noteworthy feature. Users can charge the battery from 0% to 80% in as little as 50 minutes and store it away until it’s time to use. Note that portable power stations store energy; they don’t generate it. Out of the box, you’ll need to charge the battery using a wall plug or car adaptor. 

However, adding solar panels transforms the DELTA 2 into a solar generator. Then, you’ll harness the power of the sun and generate clean, renewable energy! 

What Makes the DELTA 2 Different?

The DELTA 2 puts safety, convenience, and comfort first — all while staying green. Here’s a snapshot of the main reasons this is a one-of-a-kind portable power station: 

  • Expandable battery up to 3,040Wh
  • Smart App Controls 
  • Fast charging (80% in 50 minutes) 

Expandable Battery 

The DELTA 2 has a capacity of 1024Wh, which is enough to power up a refrigerator or TV for a few hours. However, if you need to power up an entire home or plan an extended camping trip, you can, thanks to the DELTA 2’s expandable capacity. 

The DELTA 2 lets you double or triple the power according to your energy needs. Grow your storage up to 3040Wh. If you need around 2kWh of power, add the DELTA 2 Extra Battery. If you need around 3kWh, you’ll want to add the DELTA Max Extra Battery. 

With an expandable capacity of 1-3kWh, this station will be ready to power up everyday appliances, restore power during outages, or ensure reliable, lasting power on those extended camping trips. 

App Compatibility 

Manage the DELTA 2 by downloading the EcoFlow app on your smartphone. The app lets you connect to the station via Wi-Fi or Bluetooth. 

The energy management app shows vital information like charging data, how much power your appliances are pulling or how much electricity you have in reserve. Using the app, you can even turn on and power off your device remotely. 

Control your DELTA 2 anytime and from anywhere using the EcoFlow App.

Innovative Technology 

Thanks to the technology integrated into DELTA 2, users experience the fastest charging times (80% in 50 minutes). If using solar energy, they can quickly recharge using the sun’s power in 3-6 hours. 

Here are the leading technologies you’ll receive with the DELTA 2: 

  • X-Boost. Thanks to this technology, users can power almost all of their appliances. You can’t say the same for other products of the same rated output class. The X-Boost technology also prevents the overloading of devices up to 2400W, which prevents them from getting damaged.  
  • X-Stream. The DELTA 2 charges seven times faster than the competition. Go from 0% to 80% in just 50 minutes and a full charge in 80 minutes.
  • EcoFlow App. Control and manage your DELTA 2 straight from your phone. As long as you have Wi-Fi or Bluetooth, you can control it from anywhere.

Part of an Ever-Growing EcoSystem 

When using DELTA 2, you’ll have all the tools to deliver a one-stop solution for your household’s energy needs. Connect it to several EcoFlow products, including portable solar panels, power kits, or extra batteries.

If you purchase EcoFlow Portable Solar Panels separately, you can charge the battery using solar energy. It only takes 3-6 hours when using a 500W solar panel.

The DELTA 2 also fits into the Smart Home Ecosystem, which includes: 

  • Smart Batteries allow users to expand capacity and run larger devices for longer.
  • Smart Generator, an emergency option that integrates with the DELTA 2 to charge it quickly and efficiently using petrol or propane.

How Does the DELTA 2 Compare To Other Competitors?

The EcoFlow DELTA 2 is more than just a battery. It’s the only portable power solution you need! 

Able to charge in less than an hour, you’ll enjoy the time saved compared to other brands. The handles and lightness also make this power station convenient for travel. Take it with you camping, tailgating, or use it to power up your RV on holiday! The possibilities are endless when it comes to the DELTA 2 Portable Power Station. 

Direct competitors of the DELTA 2 include Jackery and Anker. Let’s see how it compares to similar models.

Expandable Power 

The DELTA 2 has a capacity that can expand up to 3040Wh, which is enough power to energise your entire home during an outage! The other models on this list don’t provide the added capacity, making the DELTA 2 a wise choice if you’re looking for the possibility of expanded power.

The DELTA 2 has expandable power from 1024 to 3040Wh, meaning you can double or triple the output. Anything you need powered, this portable power station can handle. 

Considering the rise of power cuts in the UK, you want a reliable backup energy system. The DELTA 2 delivers. 

More Efficient Battery

Further, the DELTA 2 runs on an LFP battery that runs for 3,000 battery cycles. Competing brands like Jackery only offer 500 battery cycles. The DELTA 2 offers 6x longer cycles! 

As for battery type, both EcoFlow and Anker use LFP batteries, a Lithium-ion battery known for their more expansive energy storage and longer-lasting battery life.

Jackery uses NCM batteries, touted for their excellent performance but not-so-great battery life.

Charging Ports 

The EcoFlow DELTA 2 has 15 output ports, significantly more than the others on the list. 

You can power more than 90% of home appliances with the substantial AC output. Need to connect 15 devices all at once? Thanks to the integrated X-Boost technology, you don’t have to worry about overloading your devices (up to 2400W). 

On one side of the DELTA 2, you’ll have an easy-to-read screen that showcases charging status and input/output power. Underneath, you’ll find the ports followed by an on/off button. You’ll find more charging options on the opposite side. 

The casing of the DELTA 2 also has two handles, one on each side. Carrying handles make it easier to transport. It also protects any plugged-in cables from accidental damage since you won’t be able to push them against the wall accidentally.

Wi-Fi & Bluetooth Supported 

All four portable power stations are lightweight, compact, and easy to carry. However, there are a few distinctions that DELTA 2 has that the others don’t. 

The DELTA 2 is Wi-Fi and Bluetooth-supported, for instance. Users can connect the power station to the EcoFlow app and view important information like charging time or how much energy a specific appliance is expending. 

Easy to use and download, the app is a perk unique to EcoFlow that you don’t see with other portable power stations.


Portable power stations don’t come cheap, but with all the features offered by the DELTA 2, you’re getting a fantastic deal. 

The most expensive portable power station on this list comes from Anker, followed by Jackery.

Despite its various features and benefits, the DELTA 2 sits lower on the spectrum for pricing. 

And, except for one Jackery model, all the portable power stations featured in this guide have a warranty of 5 years. The guarantee gives buyers a worry-free experience.
