The new Delta 3 Plus is a perfect fit for us. The unit is easy to carry and the watt hours will fit nicely for outages when we want to keep our refrigerator operating. The charge rate is very fast. Good Job! - David F.
EcoFlow DELTA 3 Plus Portable Power Station | 1024Wh | 1800W | 1000W Solar Input
The EcoFlow DELTA 3 Plus Portable Power Station Pairs 1800W Output With Up to 1000W of Solar Charging
The EcoFlow DELTA 3 Plus is a portable power station with a 1024Wh LiFePO4 (LFP) battery, 1800W of pure sine wave AC output at 120V, and solar input of up to 500W per XT60i input and 1000W in total. It adds 140W USB-C ports, an Extra Battery port and a 10ms UPS function.
It suits homeowners who want outage backup for essentials and home office gear, and campers and RV owners who charge from the sun or the road. This page offers it on its own or with a DELTA 3 Expansion Battery, one or two 220W bifacial solar panels, an 800W Alternator Charger, or a combination.
EcoFlow DELTA 3 Plus Portable Power Station Features
1800W Output With 3600W Surge and X-Boost
The AC outlets share 1800W at 120V, with 3600W of surge. X-Boost, turned on in the EcoFlow app, runs appliances up to 2600W at 120V. EcoFlow says it suits heating devices such as an electric blanket or water heater, does not support devices with voltage protection, and is unavailable while the unit charges from AC.
10ms UPS With PC and NAS Monitoring
Plugged into a wall outlet, the DELTA 3 Plus acts as a standby UPS with a 10ms transfer time. It needs more power from the grid than your devices draw so it can keep its battery charged. Through a USB-C data cable, sold separately, EcoFlow's Power Manager software for macOS, Windows and Linux lets a PC or NAS monitor the power station and configure UPS settings.
Up to 1000W of Solar Input
Each XT60i input takes up to 500W of solar at 11–60V and 15A, for 1000W in total. The same inputs accept 12V at 8A from a vehicle's cigarette lighter socket. It also charges from AC at up to 1500W, and from an EcoFlow Smart Generator, alternator charger or PowerStream microinverter through the Extra Battery port.
Expandable LFP Battery From 1kWh to 5kWh
The LFP battery keeps 80% or more of its capacity after 4000 cycles. The Extra Battery port accepts the DELTA 3, DELTA Pro 3, DELTA 2 or DELTA 2 Max Smart Extra Battery for 1–5kWh of capacity, so you can start at 1024Wh and add more later.
140W USB-C and 12V Outputs
The USB-C ports deliver up to 140W per port and 280W in total. The USB-A ports deliver 36W per port and 72W in total. A 10A cigarette lighter port and DC5521 ports share 126W for car fridges, routers and security cameras.
App Control Over Wi-Fi or Bluetooth
The EcoFlow app connects over Wi-Fi, or locally over Bluetooth. You can set a Backup Reserve level, use TOU (time of use) mode, schedule tasks and turn on Storm Guard, which quickly tops up the battery from grid power.
Extra Battery, Solar Panel and Alternator Charger Options
The DELTA 3 Expansion Battery option is EcoFlow's DELTA 3 Series Smart Extra Battery. It adds 1024Wh of LFP capacity, weighs 21.2 lb (9.6 kg) and can be stacked with the DELTA 3 Plus. Each 220W bifacial panel weighs 15.4 lbs (7 kg) and includes a 2.5m Solar to XT60i Charging Cable. The 800W Alternator Charger charges at up to 800W while you drive, depending on how the vehicle is moving and its model.
Real-World Applications
Home office and network gear. Keep a computer or NAS running through outages, and let it monitor the power station over USB-C.
Home outages. Keep a refrigerator, lights and a router running when the grid fails. For a refrigerator, set the AC timeout to "never" in the EcoFlow app so idle periods don't turn the outlets off.
Camping and RV travel. Recharge from 220W panels at camp, or let the 800W Alternator Charger use your vehicle's alternator while you drive.
How It Compares to Common Alternatives
Versus the DELTA 3 Max. The DELTA 3 Max stores 2048Wh with 2400W of rated output and 4800W of surge. The DELTA 3 Plus starts at 1024Wh and 1800W, weighs 27.6 lbs, takes up to 1000W of solar, and expands to 5kWh.
Versus buying more capacity up front. Starting with the DELTA 3 Plus alone keeps the unit at 27.6 lbs. The DELTA 3 Expansion Battery adds 1024Wh later in a separate 21.2 lb pack.
Versus a gas generator. A gas generator needs fuel and has to run outdoors. The DELTA 3 Plus stores energy from the wall, the sun or your vehicle, and switches connected devices to battery in 10ms.
Is This Portable Power Station the Right Fit
Weight. It weighs 27.6 lbs (12.5 kg) and measures 8.0 x 15.7 x 11.2 in. Don't carry it onto a plane.
Solar limits. Keep each input within 60V open circuit voltage and 15A short circuit current. The Solar to XT60i Charging Cable is sold separately unless your panel includes one.
Shared Extra Battery port. Extra batteries, the 800W Alternator Charger, EcoFlow Smart Generators and the PowerStream microinverter all connect through the Extra Battery port.
Keep it dry. Don't get it wet. It charges at 32°F to 113°F (0°C to 45°C).
Medical equipment. It is not intended for life-sustaining medical equipment.
This may be a good fit if
You want 1024Wh and 1800W in a 27.6 lb unit
You want up to 1000W of solar charging
You want a 10ms UPS that your PC or NAS can monitor
You may add capacity later, up to 5kWh
Common Questions
Which Extra Batteries Work With the DELTA 3 Plus?
EcoFlow lists the DELTA 3, DELTA Pro 3, DELTA 2 and DELTA 2 Max Smart Extra Batteries, for 1–5kWh of capacity.
Do the 220W Panels Work With the DELTA 3 Plus?
Each 220W panel is rated at 21.5V open circuit and 12.4A short circuit on its front side, and comes with a Solar to XT60i Charging Cable. The DELTA 3 Plus accepts up to 60V and 15A per input.
How Does the 800W Alternator Charger Connect?
It wires to a 12V or 24V vehicle starter battery or RV house battery with its 5m Input Cable and Fuse Cable, and its 1m XT150 Output Cable plugs into the Extra Battery port. EcoFlow recommends professional wiring.
What Warranty Does It Have?
EcoFlow gives the DELTA 3 Plus a 5-year warranty. The manual notes that coverage does not apply if the power station is not charged or discharged for more than 6 months, so cycle it every 3 months in storage.

I'm Very Happy With My Purchase
Outbound Power was fast to answer my questions in live chat and that helped much! I received my Ecoflow Delta 3 Plus and 220 watt bifacial solar panel in timely fashion and all was packaged well. Later after reading the manual I ran my Starlink router along with an iMac and MacBook Air M1 plus a rather large sound system hooked into the iMac. All that was using about 140 watts of power. When the Delta 3 Plus was at 70% of charge I hooked the 220 watt bifacial solar panel to it and quickly was pulling 186 watts of charge from solar! Really good since I really didn't fuss much with the alignment of the panels to the sun. Note that the Delta 3 Plus will need the xt60i cable, the orange colored one, to get the most out of the solar panels. The xt60i has a center contact that is supposed to be bonded to the negative wire of the cable. Watch out on Amazon and some other online suppliers that may sell xt60i cables that have not been wired correctly meaning the center contact is there but not wired to either positive or negative. The Delta 3 Plus will work best with the orange plug xt60i not the yellow plug xt60 cable. This power station runs my 15 amp Skilsaw with ease! Full of big surprises!
Hi Stephen,
Wow—thank you for such a detailed and thoughtful review! I’m so glad to hear your Delta 3 Plus and 220W bifacial panel are working so well for you. It’s great that you were able to power everything from your Starlink setup to your Skilsaw with ease—that’s exactly the kind of versatility we love hearing about.
I also really appreciate you taking the time to share your insights about the XT60i cable. Tips like that are incredibly helpful for other customers and show how much real-world experience you’re putting into your setup.
It’s a pleasure having you as part of the Outbound Power family, and we’re here anytime you have questions or new projects in mind. Wishing you plenty of smooth solar charging and reliable backup power ahead!
All the best,
Bill

Delta 3 Plus- perfect
Bought three of these as pass-through backups for several appliances! Perfect for what I need. Lost power to our church and took a few of these to run the mic system and fans and refrigerator- performed perfectly, they saved the day! They are portable, reliable and the way you can control these with the app gives you a lot of peace of mind.
Hi Mark,
Thank you for such an outstanding review! It’s inspiring to hear how your three Delta 3 Plus units aren’t just serving as reliable backups at home, but also stepping in to support your church community when the power went out. That’s exactly the kind of real-world impact these systems are designed for — keeping essential appliances and equipment running without missing a beat.
We love that you’re making the most of the portability and app control features, too. Having that flexibility and peace of mind, especially during outages, is invaluable. It means a lot to know that Outbound Power could play a small part in making sure everything kept running smoothly for you and your community.
We truly appreciate your trust in us and look forward to supporting your power needs as they grow.
With gratitude,
Bill & the Outbound Power Team

Great!
Great! As soon as I opened the “have a question?” for an inquiry, I was like “wha..? It’s an actual person!? Very nice too. Answered my question promptly. And I think it was a Saturday, too. So I did NOT expect that. The price/deal was great! It really was the lowest price I could find. At checkout, I wasn’t surprised by other fees and taxes to increase the price. Then the nice follow up emails were a plus. Even though I’m sure those were automated, but still. It’s nice
Hi Michael,
Thank you for your kind words — your feedback truly made our day!
We're so glad our live chat support was a pleasant surprise (even on a Saturday!) and that you found the best deal with no hidden fees. We do our best to keep things simple, helpful, and honest, and it’s great to know that came through for you.

Best prices online
I was given a 17% discount on the EcoFlow Delta 3. That brought my price down to the lowest I could find and it tipped me over into purchasing. So far, I have not had a need for any support. The product is very easy to use, very quiet. I can't wait to try it out on our off-grid property up in Colorado.
Thank you for sharing your experience! We're thrilled the 17% discount helped you make the leap, and even more so to hear you're enjoying your EcoFlow Delta 3. It sounds like a perfect fit for your off-grid adventures in Colorado! If you ever need assistance or have questions down the road, don’t hesitate to reach out. Wishing you many smooth and quiet power experiences ahead!
This extra expansion battery works great and makes a big difference by adding more time to my critical loads taking my family safely through the night.
Hi Tony, thanks for sharing your experience! We’re glad the expansion battery is working great for you. Please let us know if we can ever be of service again!
Excellent product. Very well made, easy to use. Decreases from the solar panel only 1- 3%, negligible amount. I'm satisfied with the product completely.
Hi Carlton, thanks for the great review! We’re glad the cable is working so well for you. We really appreciate your support!
The unit works wonderfully for my purposes. The solar panel was putting out maybe 165 W max for me possibly because I'm using the 15 ft extension cord but it still charges decently. Not letting it discharge over 25% is key. Customer service was awesome. Very friendly people and helpful. I recommend this unit and buying from Outboundpower. 5 ⭐ all around. Thank you.
Hi Carlton, thanks so much for the wonderful review! We’re delighted your Jackery is working well for you and that our team could help. We appreciate you sharing your solar charging experience and recommending Outbound Power. Enjoy your power station!
The product arrived promptly and in perfect condition. I have run it on AC and it cooled quickly. The staff at Outbound Power switched my order to a grey color after the order but before shipping and never missed a beat. They were great.
Thanks so much for the five-star review! We’re glad your freezer arrived promptly and in perfect condition, and that it cooled quickly on AC. We’re also happy we could switch your order to grey before shipping. We truly appreciate your kind words and your support!

Generator works. Have yet to try solar panels. Will have to wait for a sunny day! Just wish I was more tech-savvy. Feel a little overwhelmed… but I am satisfied w purchase
Hi there, thanks for sharing your experience! We’re glad you’re satisfied with your purchase. It’s completely understandable to feel a little overwhelmed at first—enjoy trying the solar panels when the sun comes out, and please reach out if you need a hand getting started!
Thank you for your review! We're glad to hear your Jackery solar panel is performing well, even on cloudy days. We truly appreciate your business and thank you for choosing Outbound Power!
