EcoFlow DELTA Pro Portable Power Station (3600Wh, 3600W)
The DELTA Pro is the machine that made portable home backup a realistic idea rather than a compromise. 3600Wh of LFP storage and 3600W of pure sine wave output is enough to run a refrigerator, a well pump, a furnace fan and your lighting circuits at the same time — and with two extra batteries it climbs to 10.8kWh, which will carry a household through most outages.
It charges faster than almost anything in its class: 1.8 hours from a wall outlet, or up to 6500W when you combine AC and 1600W of solar. Add the Double Voltage Hub and two DELTA Pros deliver 240V for a well pump or dryer. Build the configuration you need below — extra batteries for runtime, solar for independence, an alternator charger for the road. Renewable Outdoors is an authorized EcoFlow dealer; call us at (303) 876-7654 and we'll help you get the combination right.

Why the DELTA Pro
3600W Output, 7200W Surge
Runs full-size household appliances, not just electronics. X-Boost pushes resistive loads up to 4500W without tripping.
Expandable to 10.8kWh
Two DELTA Pro Smart Extra Batteries triple your storage, and they plug in rather than needing an installer.
Full Charge in 1.8 Hours
MultiCharge combines AC and solar for up to 6500W of input — the fastest recharge in this capacity class.
240V with the Double Voltage Hub
Pair two DELTA Pros through the hub for 240V output — a well pump, a dryer, or a 240V circuit in your panel.
3,500 Cycles to 80%
LFP cells rated for 6,500 cycles to 50% capacity, which is roughly a decade of daily cycling.
1600W of Solar Input
A wide 11–150V MPPT window, so it works with EcoFlow panels and with most third-party arrays.

Building Your DELTA Pro
There are three separate decisions to make on this page, and they answer different questions. Work through them in order — the power station itself is identical in every configuration.
Decision
Your Options
How to Choose
Battery Option
No extra battery (3600Wh) · 1 extra battery (7200Wh) · 2 extra batteries (10,800Wh)
This sets how long you can run, not how much you can run — output stays 3600W either way. One extra battery is the sweet spot for whole-house essentials through an overnight outage; two is for multi-day outages or full-time off-grid use.
Solar Panel Option
None · 1 × 220W · 1 × 400W · 2 × 220W · 2 × 400W
Solar is what removes your dependence on a wall outlet. The unit accepts up to 1600W, so even two 400W panels leave headroom to add more later. If you're buying purely for grid outages, panels matter less than batteries; if you're camping or off-grid, they matter more.
Charger Option
No alternator charger · 1 × 800W Alternator Charger
The alternator charger lets you refill the DELTA Pro from your vehicle's engine while you drive — up to 800W, far faster than a 12V socket. Worth it for overlanding, van life and mobile work; unnecessary if the unit lives at home.
Runtime scales with batteries, output does not. If you need to run more at once rather than for longer, the answer is a second DELTA Pro with the Double Voltage Hub rather than extra batteries. Call us at (303) 876-7654 and tell us which limit you're actually hitting.

EcoFlow DELTA Pro Portable Power Station (3600Wh, 3600W): Frequently Asked Questions
How long will the DELTA Pro run my house during an outage?
3600Wh is the figure to work with, and you divide it by your actual draw. A refrigerator averaging 150W, some LED lighting and a few devices comes to roughly 250W, which is around 13 hours. Add a furnace fan and it drops to five or six. With two extra batteries you're at 10,800Wh and those numbers roughly triple. Call us at (303) 876-7654 with what you want to keep running and we'll do the arithmetic with you.
Can it run a 240V well pump or dryer?
Not on its own — a single DELTA Pro is 120V. Two DELTA Pros connected through the EcoFlow Double Voltage Hub give you 240V and up to 7200W, which covers most residential well pumps and electric dryers. We stock the hub and can confirm your pump's starting surge before you commit.
What is X-Boost, and when do I need it?
X-Boost lets the DELTA Pro run resistive devices rated above its 3600W continuous output — heaters, kettles, hair dryers, up to about 4500W — by slightly reducing the voltage delivered to them. It works well for heating elements and motors that tolerate it, and it isn't appropriate for sensitive electronics. It's a switch in the app you turn on when you need it.
How many extra batteries can I add, and can I add them later?
Up to two per DELTA Pro, taking you from 3600Wh to 10,800Wh. They're plug-and-play, so adding one later is genuinely straightforward — no installer, no rewiring. Each extra battery needs its own connection cable, so check you have one when you order.
How fast does it charge, really?
From a standard wall outlet, about 1.8 hours to full. If you combine AC and solar with MultiCharge you can push 6500W of total input. Solar alone tops out at 1600W, so a full recharge from panels depends entirely on your array and the weather.
What's the difference between the DELTA Pro and the DELTA Pro 3?
The DELTA Pro 3 is the newer generation: 4096Wh, 4000W, and native 120/240V output from a single unit without needing a Double Voltage Hub. The original DELTA Pro remains an excellent buy for 120V backup and has a much larger accessory ecosystem behind it. If native 240V matters to you, look at the Pro 3; if it doesn't, the DELTA Pro delivers more capacity per dollar. Happy to talk it through on (303) 876-7654.
Do I need the 800W Alternator Charger?
Only if you'll be charging from a vehicle. It draws from your alternator at up to 800W while the engine runs — roughly eight times what a 12V cigarette socket manages — which makes it genuinely useful for van life, overlanding and mobile work. If the DELTA Pro lives in your basement, skip it.
Can I use it as a UPS for a computer or medical device?
Yes. The DELTA Pro passes through wall power and switches to battery when the grid drops. Switchover is fast enough for computers and networking gear. For medical equipment, check the specific device's tolerance with its manufacturer first — we'd rather you confirm that than assume it.
Is it safe to use indoors?
Yes — there's no combustion and no fumes, so unlike a gas generator it's designed to sit in a hallway or basement. It has LFP cells with a battery management system monitoring temperature, current and voltage. Keep it somewhere dry with air circulation around the vents.
Do you offer financing or price matching?
Yes. We offer 0% APR financing options through Affirm at checkout, and our Lowest Price Guarantee applies — if you find this configuration cheaper at another authorized dealer, call us at (303) 876-7654 before you order and we'll take care of it.
Customer Reviews
Overall rating: 4.8 / 5 from 42 reviews.
Ecoflow delta pro is great! blessed to have one. renewable outdoors was great. Will be buying from them again
This is a great product. It was quite easy to set up. I then plugged it into my electric panel utilizing a 50 amp breaker and an interlock switch. I ran it down to 1% then plugged it into a 20 amp outlet to recharge . It charged to 100% in 2.5 hours. Once my budget allows it, I will get the battery pack for it to double the storage capacity .
Delta Pro is great for emergency backup and I can also use it to charge my electric motorcycle. It is relatively mobile with the wheels and light enough to pickup for outdoor usage.
My purchase from Renewable outdoors has been a pleasurable experience. Worked with Travis and have nothing but good to say. The Delta pro is all that I expected for the application I intended. I may in the near future purchase an extra battery and possibly solar panels. Thank you Travis and Renewable.

Absolutely love the EcoFlow Delta Pro! I ordered after the holidays and couldn’t wait to try it out for real. We had a storm pass through last week and lost power for over 3 hours…it worked flawlessly! Now I can’t wait to purchase the solar panels next to feed the beast!
Travis and Aron are fantastic!
Always available and extremely helpful…thank you!
The purchase of the EcoFlow Delta Pro 3600W battery from Renewable Outdoors was a great experience! I saved significant money over ordering from Home Depot and other online stores. My concerns over ordering online were quickly overcome by their order processing, shipping and delivery all within 4-5 total days. I also had questions for them and they were very responsive to my emails. Great job!
Best price anywhere, shipped in a very timely manner and arrived as expected. I already had one but needed a second to power my entire cabin. Great experience and highly recommend.
Delta Pro arrived within 4 or 5 days after placing the order. It was a new unit correct model
as advertised. Everything worked as it should have. No problems with any on board features. I have not tried solar charging because there has been no sunshine. This is a well made product at a good price. I am satisfied with the purchase.
I like the system but it won’t charge using your EV adapter from my Audi 220 wall charger. Been in touch with service but haven’t had time to do a video. I plug it in and nothing happens. No change to screen at all. Have you had other reports of it not working?
Updated firmware even before I tried it
I bought the Ecoflow Delta Pro. Renewable Outdoors gave me a great price on an excellent product with a fast delivery. I will deal with them again. 5 stars !!!!
The Delta Pro works great right out of the box! Renewable Outdoors did a good job coordinating some complicated shipping requirements to send it to me in Alaska, and they bent over backwards to make sure it all went well. I would definitely do it all over again.
All in all everything went well with my purchase of the Power Station. My emails back and forth to Renewable Outdoors about a few questions I had went just fine, and were timely replied to with answers to my questions. The shipping speed was acceptable and so far the product has performed very well also. Overall I am pretty satisfied with the purchase process and the product. Oh and the cost was actually great!
Very durable and versatile power station. I love its simplicity and its design. The Delta Pro easily keeps all of my amenities up and running in my off-grid cabin. Amazing performance for a great price.
Unquestionably 10 out of 10.
I certainly would recommend.
Used the eco flow pro two days after receiving it. Powered our gas furnace in a unexpected power outage. The unit worked great. Very happy with the purchase. Shipping also went very well.
Thank You

I have an EV. I need a little more range than the car offers. I’m using the EcoFlow to charge my car while I’m in working at my job. It gives me just enough charge to drive home. Probably gives me an extra 8 miles driving distance. Just what I need to make the round trip to and from work.
À way to have protection against power outage I can run a sump pump till I can get a generator running,, seems to be a simple solution or I can get heat from the pellet stove,mike Willington Ct
I gave this unit 4 stars because it did not come with better operating instructions. Also, the charging cable should be 2.5 meters long rather than 1.5 meters. Charging the power station was easy, either by electrical outlet, or by my small Honda generator. Because I purchased these Delta Pro units for hurricane season, I have not had a chance to use them. I am confident that they will meet my needs.
It is working great!
However, the 220v outlet is misleading. It doesn't work even with a smart battery attached to start up a 220v appliance...1 hp well pump.
Sincerely,
Frank Johnson...Greenfield, MO
