The EcoFlow Delta Pro Ultra is designed to keep your entire home running during a blackout or power all your devices on a remote camping trip. This powerhouse of a portable battery offers high-capacity energy storage, flexible charging options, and multiple output ports to suit a variety of needs.

Output Options

Versatility is key when it comes to output options, and the EcoFlow Delta Pro Ultra doesn't disappoint. It features six AC outlets that together provide up to 7200W of output power, making it capable of running most home appliances.

The two USB-A ports deliver a total of 24W, while the two USB-C ports offer up to 200W, perfect for charging smaller gadgets such as phones, tablets, and laptops. It includes a single DC output outlet that maxes out at 378W, ideal for car accessories and other DC-powered devices.

This wide array of ports means you can power or charge multiple devices simultaneously without the need for additional adapters or power strips.

Charging Capabilities

The EcoFlow Delta Pro Ultra has several recharging options:

  • Grid-tied AC: Plugging the Delta Pro Ultra into a standard wall outlet is one of the quickest and most straightforward ways to recharge. This method allows you to fully charge the unit in about 2.7 hours, making it convenient for home use.

  • Smart Generator (Dual Fuel): The Smart Generator, which supports dual fuel (gasoline and propane), can be used to recharge the Delta Pro Ultra. This option is particularly useful during prolonged power outages or in remote locations where other charging methods may not be available.

  • Solar Charging: If you're off the grid, you can connect solar panels (sold separately) to recharge it in about 4-8 hours, depending on the solar input. The Smart Home Panel 2 integration allows seamless switching between grid power and the Delta Pro Ultra, ensuring your home stays powered during outages and optimizing energy use from the grid and stored solar power.

  • DC (Car Adapter): On the go? You can use a car adapter to recharge the Delta Pro Ultra while you drive. This method is perfect for road trips, ensuring that you always have a reliable power source for your devices and appliances.

  • EV Charging: One unique feature is its compatibility with electric vehicle charging stations, allowing for a quick charge at any EV station.

Portability and Design

The EcoFlow Delta Pro Ultra weighs around 187 lbs, which is hefty but manageable thanks to the built-in wheels and sturdy handles. The design is practical for both home use and transportation, making it easy to move around as needed.

Its sleek, robust design not only looks good but is also built to withstand the rigors of outdoor use. Whether you're setting up a mobile workstation or need a reliable backup during a power outage, this unit's design ensures it can handle the task.

App Integration

Another standout feature of the EcoFlow Delta Pro Ultra is its seamless integration with the EcoFlow app. This app isn't just an add-on; it's a powerful tool that enhances your control and monitoring of the power station.

With the app, you can monitor real-time data such as battery level, input/output power, and remaining run time. You can also manage multiple charging options and adjust settings remotely. You are able to check your Delta Pro Ultra's status from anywhere—be it at work, in bed, or even while traveling.

You can ensure that your device is charging efficiently, troubleshoot issues, and even update firmware to keep your system running smoothly.  

Smart Home Integration

Connecting the Delta Pro Ultra with Smart Home Panels further enhances its capabilities. This integration allows for automatic and seamless switching between grid power and the Delta Pro Ultra during outages.

The Smart Home Panels can connect up to ten home circuits, ensuring that your most critical appliances and systems stay powered without interruption.

This integration also boosts your home automation and energy management. You can set preferences for which circuits receive power, monitor energy usage, and optimize your power consumption based on real-time data.

This not only provides peace of mind during emergencies but also helps you manage your home’s energy efficiency, potentially lowering your electricity bills.

Installation and Setup

You can install the Ecoflow Delta Pro Ultra yourself but professional installation services are recommended, especially when integrating with your home’s electrical system via the Smart Home Panel.

Professionals can ensure that everything is set up safely and correctly, optimizing your system’s performance. To keep your unit in top condition, avoid direct sunlight, ensure proper ventilation, and regularly check for firmware updates via the app. 


The EcoFlow Delta Pro Ultra comes with a five-year warranty which covers any defects in materials or workmanship under normal use, ensuring you have support if anything goes wrong.

While the five-year warranty is shorter than some industry standards, the robust performance and extensive support network provided by EcoFlow help address this difference, making the Delta Pro Ultra a dependable choice for reliable power storage.

Home Backup Power

One of the biggest benefits of the Delta Pro Ultra is its ability to serve as a reliable home backup power source. Think about the peace of mind that comes from knowing your essential appliances—like refrigerators, microwaves, and even washing machines—will keep running during a power outage.

The Delta Pro Ultra's 6 kWh battery capacity makes this possible, ensuring you don’t have to worry about food spoiling or losing access to important devices.

But there’s more... The integration with Smart Home Panels takes this convenience to another level. This feature allows for seamless switching between grid power and your Delta Pro Ultra. During a blackout, the transition is so smooth that you might not even notice it.

Your lights stay on, your devices keep running, and life continues uninterrupted. So, even if a storm hits and your neighborhood loses power—your Delta Pro Ultra kicks in immediately, keeping your home running smoothly until the grid is back online.

Outdoor and Off-Grid Use

Now, if you’re an outdoor enthusiast or someone who loves off-grid living, the Delta Pro Ultra is a game-changer. Its design is rugged yet portable, with built-in wheels and sturdy handles that make transporting it a breeze.

Whether you’re camping in the wilderness, embarking on an RV trip, or setting up a remote work site, this power station is built to withstand the demands of outdoor use. Durability is crucial when you’re off the grid. The Delta Pro Ultra can handle rough conditions, and its ability to charge via solar panels means you can stay powered indefinitely as long as you have access to sunlight. 

How Much Does The EcoFlow Delta Pro Ultra Cost?

When considering the EcoFlow Delta Pro Ultra, it's essential to look at both the upfront cost and the long-term value. Currently, the Delta Pro Ultra is priced at around $5,799 excluding installation. 

But is the Ecoflow Delta Pro Ultra Worth the Price?

The cost  might seem steep at first glance. However, investing in the Delta Pro Ultra can actually save you money in the long run. How? Well, consider the cost of traditional backup power solutions like fuel generators.

These not only require ongoing fuel purchases but also regular maintenance. In contrast, the Delta Pro Ultra runs on renewable energy (when paired with solar panels), eliminating fuel costs and reducing maintenance needs.

Its longevity means you're looking at years of reliable service, whether you're using it for home backup, outdoor adventures, or as part of your everyday energy strategy.

Over time, the savings on fuel, maintenance, and potentially even energy bills (if you use it to offset peak electricity rates) can make this an economical choice.
