EcoFlow Delta Pro 3 against a white background

Pushing out up to 50 amps, the EcoFlow Delta Pro 3 is a perfect choice for plugging straight into your RV or as a key part of your home backup setup. It comes with a 400W solar panel right out of the box, but if you’re looking to go big on solar, you can scale it up to 2,600W.



For a lot of homes—especially in hurricane zones or areas hit hard by natural disasters—a backup power setup is a must. That’s where something like the EcoFlow Delta Pro 3 really shines. Whether you’re looking to go solar, stay ready for unexpected blackouts, or just want to cut down on your electric bill, this portable power station has you covered.

Right now, you can snag this EcoFlow power station for just $2,684, which is $1,015 off its usual $3,699 price tag. That’s the lowest it’s ever been. Keep in mind, though, that you’ll need an active Prime membership to grab the deal.

What’s great about the EcoFlow Delta Pro 3?

The EcoFlow Delta Pro 3 packs one of the biggest batteries you’ll find in a portable power station, meaning it’ll keep things running way longer. It’s built to handle heavy-duty gear with 120V/240V and 4000W output options, and it charges up fast too. You can use it on its own, hook it up to solar panels, or pair it with the EcoFlow Smart Home Panel 2. It even works with a standard inlet box or transfer switch for extra setup options.

Weighing in at around 52kg, the EcoFlow Delta Pro 3 might sound hefty, but thanks to its built-in wheels and retractable handle, it’s surprisingly easy to roll around. Where it really flexes, though, is in its power. It kicks off with a solid 4kWh of capacity, which you can expand all the way up to 12kWh with two extra batteries. You’ll get a steady 4,000W output, which is more than enough for most situations. But if you need a burst of serious muscle, it can surge up to 6,000W.

Since the Delta Pro 3 is a battery and not a gas generator, you can safely run it indoors without worrying about carbon monoxide—that’s a big win. Additionally, it’s built to slot right into your existing EcoFlow backup setup. And if you need more juice, you can scale it up to a massive 48kWh by linking three units, each with two extra batteries.

The Delta Pro 3 isn’t exactly cheap, but with the current discount, it’s a killer deal. Whether you’re gearing up for off-grid camping or want a rock-solid backup at home, this high-capacity battery’s got you covered.
