Through this comparison guide, we’re confident you’ll find many reasons that make the new DELTA 2 the ideal choice for a portable power station. We review specific metrics, using detailed information comparing DELTA 2 and its immediate competitors. By the end, you’ll have an informed opinion. 

Let’s take a closer look. 

Introducing the New DELTA 2 Portable Power Station

The DELTA 2 is no ordinary power station. It can power 90% of home appliances with 1024Wh capacity and expandable power capacity up to 3040Wh if you need it. It charges exceptionally fast thanks to its unique X-Stream technology, reaching 80% in just 50 minutes, and possesses the highest power output in its weight category.

Speaking of weight, the DELTA 2 weighs just 27lbs (12kg), making it highly portable. You can take it anywhere you need to, inside or outside the home, and stay powered up for longer. 

Innovative technology puts complete control in your hands through the DELTA 2’s Bluetooth and Wi-Fi connectivity and smartphone app. Innovative design lets you control and track power use through the PPS metrics. 

What Makes the DELTA 2 Different?

The DELTA 2 is not only highly efficient, but it’s also unique. From patented technology to innovative design, the DELTA 2 meet the needs of an ever-changing world. Listed below are just a few ways that it achieves this aim. 

Driven by Eco-Friendly Motives

The world is continuously moving towards greener ways of doing things and recognizing the importance of renewable energy. By now, we are all aware of the dangers of climate change. Most of us understand that our planet is under severe threat if our behaviour doesn’t change to meet these new challenges. Artificial intelligence, electrification, and alternative clean energy sources are all new frontiers to explore. Why should portable power stations be left behind?

With the DELTA 2, we are proud to introduce a power station that meets your needs without compromising the climate. By adding portable solar panels, you can instantly turn your DELTA 2 PPS into a powerful solar generator at any time. 

We believe in an aspirational, eco-friendly future, and every step of our design process has reflected that. Allowing for smartphone access and utilizing solar power are just two of the many ways we push the envelope with what portable power stations can do

Patented Technology

From our Smart Charge battery to our X-Stream recharge speeds, EcoFlow thrives on innovation. The DELTA 2 benefits from multiple patented technologies that revolutionize how power stations operate. 

X-Stream enables the DELTA 2 to reach 80% charge in just 50 minutes. The Smart Battery Management system fully optimizes how your station stores and provides power, using an intelligent algorithm to provide you with the best possible results.

In short, the DELTA 2 goes the extra mile to ensure you have a positive experience.

The Next Home Essential for Your Family

Your home should feel like a sanctuary. A place where you can relax at the end of a long day and not have to worry. That’s why at EcoFlow, our focus is on family, keeping you and your loved ones safe and comfortable no matter what unexpected situation unfolds. A huge part of this is having access to electricity.

It is easy to forget just how integral power is to everything we do in our daily lives. It isn’t just vital for entertainment — it also provides light, heating, refrigeration, air conditioning, and more. With so much reliance on electricity, it’s no surprise that the average home uses around 893kWh per month.

It’s hard to overstate electricity’s importance, which is why we put so much emphasis on keeping your essential devices and appliances running for as long as possible. We’ve built the DELTA 2 to give you peace of mind, no matter the circumstance.

The Most Powerful in its Weight Class

The DELTA 2 provides an energy capacity of 1024Wh, outsized only by an Anker PPS. However, considering the size and weight of these stations, the DELTA 2 wins every time. The Anker PPS weighs a hefty 43.9lb (19.9kg), whereas the DELTA 2 is just 27lbs (12kg). That’s almost a 20lb difference, with the DELTA 2 still achieving an impressive power capacity. 

The Most Available Output Ports

If you want to charge as many devices as possible with your station, the DELTA 2 should be your first choice. It provides you with available ports in almost every category, including:

  • USB-A
  • USB-A Fast Charge
  • USB-C
  • Car Power
  • DC55521

No matter your requirements, you’ll have the ports to meet your needs. None of the DELTA 2’s competitors feature such a wide range of output ports. For example, Jackery’s competing PPS only offers only three AC outputs compared to the DELTA 2’s six and Jackery doesn’t support DC55521 output at all!

You won’t find versatility like this anywhere else on the market.

The Fastest Charging Speeds

The DELTA 2 can reach full charge in a much shorter timeframe than its competitors, especially given its power capacity, reaching 80% charge in just fifty minutes when connected to a wall outlet and a full charge in just 80 minutes.

Only one of Anker’s products comes close to this, reaching 80% in sixty minutes, but it is a much larger, heavier power station. 

With optional EcoFlow Solar Panels, the DELTA 2 reaches full charge within 3-6 hours. It is similar to one of Anker’s products, except the DELTA 2 provides an additional 200W power. 

Utilizes Smart Generator Charging

If you thought the high-speed charging was impressive, just wait til you experience the patented Smart Generator charging. The DELTA 2 is the only power station of its kind to utilize this. 

Smart generator charging allows the DELTA 2 to reach its full 1024Wh capacity in just 80 minutes, which is something none of its competitors can do. This kind of cutting-edge technology is just one of the ways the DELTA 2 stands out in the market. 

Wi-Fi and Bluetooth Supported

You can operate the DELTA 2 via the smartphone app, which you can’t do with any of the other competitors. Connect to the PPS using Wi-Fi and Bluetooth, depending on your needs. 

Smart, wireless technology adds new functionality to your power station, allowing you to alter settings remotely and improve energy efficiency. 

Extra Battery for Expandable Capacity

Last but certainly not least, the DELTA 2 sets itself apart by enabling expandable energy storage capacity with the addition of another battery.

You have complete control over your maximum capacity. If you look at the base product and feel like it isn’t enough, you have the option to make improvements! You won’t have this opportunity with any competing power stations.


So there you have it, a complete comparison of the DELTA 2 and how it stands up to its competitors. This portable power station excels from the fastest charging speeds to the largest power output in its weight class. You’ll feel the difference in power and speed when you try it out for yourself.
