I tested out the EcoFlow Delta Pro 3 and it's ultra-compact, ultra-high-capacity, and ultra-heavy

The EcoFlow Delta Pro 3 takes portable power to new heights. This isn't just a power station that can power your iPhone while camping; this is a power station that offers the ability to operate as a whole-home backup solution, power an RV, power an off-grid domicile, charge a Tesla, or even run an industrial popcorn machine for hours on end (more on this later).

Much like Anker Solix's F3800, I have written two pieces on the EcoFlow Delta Pro 3, the largest offering of the company's line-up. But this new model, the third-generation, boasts more capacity, faster charging, and improved expandability compared to the earlier Delta models, making it one of the most advanced consumer power stations available - and a phenomenal option for those who need high output and high capacity.

EcoFlow Delta Pro 3: Price and Availability

The base price of the Delta Pro 3 is $3,699, currently on sale for $3,199. Since its release, the cost has lowered. However, it is still a premium offering. EcoFlow is offering a handful of bundle options to expand the already impressive capabilities of its flagship power station. These include a solar panel bundle, a dual-fuel brilliant generator bundle, and an extra battery bundle that could expand the capacity to 48kWh.

EcoFlow Delta Pro 3: Unboxing & first impressions

One of the first things I noticed about the Delta Pro 3 was its compact size and incredible weight. I know batteries are heavy and regularly work with large power stations, but I was still shocked. For the power output that the Delta Pro 3 can produce, the size is not that overbearing. It does, however, weigh in at just over 113 pounds, so make sure that you either have help to move it around or that you're not going up and down stairs or loading it anywhere.

The build quality is what I would expect from a company like EcoFlow. It has an industrial-grade IP65-rated battery for dust and water resistance, too.

Another shocking thing about the design is it has a built-in telescoping handle. I expected wheels, mostly because I saw them in the picture before arrival but also because the unit is so heavy. I also noticed a carrying handle on the top, so I expected that to be it. However, once I got the unit, I saw a telescoping handle that comes out of the underside of the power station, allowing for even easier transportation without breaking your back to move the power station from place to place on the large back wheels.

EcoFlow Delta Pro 3: Design & build quality

This portable power station has a massive battery, so don't expect to take this thing hiking. However, it is crucial to note that EcoFlow has integrated some rugged wheels to get you to where you may need power the most. Outside the telescoping handle, the EcoFlow Delta Pro 3 has an industrial-grade plastic casing to help it withstand heavy use. And, while I don't think anyone would intentionally take this beast out in the rain, it is IP65-rated, making it resistant to dust and water and, therefore, suitable for indoor and outdoor use.

EcoFlow Delta Pro 3: In use

Portable power stations are something that I didn't realize how much I would use them until I had an abundance. They are so helpful not only as home backups as UPS but also as power in strange places you may not have power or even to offer a port you may not otherwise have.

I've had the EcoFlow Delta Pro 3 for many months and tested it in many scenarios. Some have been realistic and useful for the masses, and others have been highly specialized and unique to what I needed.

First, to discuss the common uses, this power station functions beautifully as a UPS and whole home backup solution. Granted, if you are trying to hook this up to run your entire house with the standard outlets, you'll need some additional pieces to wire it into your home. But, if you want to run a local dose of plugs that can be plugged into this power station, you are also in luck. This unit operates as a UPS with a 10ms switchover time, which ensures no interruptions for critical appliances or lamps, just the same.

What sets this power station apart is that it's powerful enough to output what a large generator would, but without fumes or gas. So, you can get 240v power anywhere without making room for venting a gas/diesel generator. I did this a couple of times for testing purposes to see what the capabilities are.

I was able to push the Delta Pro 3 to charge a Tesla (though, of course, not full capacity off just the internal battery, but it was able to add quite a bit of capacity to the battery while sipping off the 120v wall), I was able to run a giant industrial sized bounce house blower, and even a commercial sized popcorn machine on full power for several hours while also plugged into a 120v outlet.

This power station is phenomenal for off-grid power, running off of just the sun and some solar panels. It can be an excellent option for those trying to make a fully powered tiny home in a van or truck. It can be a fantastic option for high power on demand anywhere. It can also be an excellent option for job sites.

EcoFlow Delta Pro 3: Final verdict

The EcoFlow Delta Pro 3 is a game-changer for high-capacity portable power. With seamless smart home integration, massive battery capacity, and rapid charging options, it’s one of the best solutions for home backup, RV life, and professional off-grid power. Though heavy and pricey, its performance and versatility justify the investment for serious users needing a portable power solution.
