Model: DELTA 3 Classic Only
1024Wh · 1800W Output · 0–80% in 45 Minutes · 27 lbs

EcoFlow DELTA 3 Classic Portable Power Station (1024Wh)

The DELTA 3 Classic is the entry point to the DELTA 3 line, and at 27 lbs it's the one you'll actually carry. 1024Wh of automotive-grade full-tab LFP capacity, 1800W of continuous pure sine wave output with a 3600W surge, and X-Boost to 2600W — enough for a fridge, a microwave, or most power tools.

X-Stream charging takes it from 0–80% in 45 minutes on AC, and it accepts up to 500W of solar for a full charge in about 2.5 hours. Switchover is 10 milliseconds, it stays under 30dB at 600W, and EcoFlow rates the cells for over ten years of use. Storm Guard can even top it up automatically when severe weather is forecast. Renewable Outdoors is an authorized EcoFlow dealer — call us if you're not sure this is the right size.

Why the DELTA 3 Classic

1800W, 3600W Surge

Pure sine wave output that runs a full-size fridge, a microwave, or a circular saw — with X-Boost extending resistive loads to 2600W.

0–80% in 45 Minutes

X-Stream charging fills it from a standard wall outlet in well under an hour, managing voltage intelligently to protect cell life.

27 lbs — Actually Portable

Light enough for one person to carry to a campsite, a job site, or the car without planning around it.

Four Ways to Charge

AC, solar to 500W, car, and generator — with hybrid smart generator input up to 1400W and a full solar charge in about 2.5 hours.

10+ Years of Cells

Automotive-grade full-tab LFP cells with 24/7 BMS monitoring and an EV-grade condensation-resistant structure built for transport knocks.

Storm Guard Mode

The OASIS 3.0 app can trigger charging automatically when severe weather alerts appear, so it's full before the grid goes down.

Choose Your Configuration

Configuration What It Adds Why Choose It
DELTA 3 Classic Only The power station on its own Emergency backup and travel power where a wall outlet is your normal recharge — the lowest entry price
+ 220W Solar Panel One 220W bifacial portable panel Camping and off-grid use — a foldable panel that packs down and goes with you
+ 2 × 100W Rigid Solar Panels 200W of rigid panels Semi-permanent mounting on an RV, van, or shed roof rather than deploying and packing away each time
+ 500W Alternator Charger The 500W alternator charger Vanlife and overlanding — recharges from your engine while driving, to 80% in about 1.8 hours
+ Smart Generator 3000 EcoFlow Smart Generator 3000 (dual fuel) Extended outages with no sun — the generator starts and stops itself as the battery needs it
+ WAVE 3 EcoFlow WAVE 3 portable air conditioner Cooling a tent, van, or room off-grid — bear in mind an air conditioner will drain 1024Wh quickly

A word on the WAVE 3 bundle: it's a genuinely useful pairing for camping, but 1024Wh won't run an air conditioner all night. If cooling is your main goal, talk to us about a larger power station or adding solar — call (303) 876-7654 and we'll be straight with you about the runtime you'd actually get.

What's Included

EcoFlow DELTA 3 Classic

In the Box

  • EcoFlow DELTA 3 Classic power station
  • AC charging cable
  • User manual
  • Warranty card

Bundle configurations add the solar panels, alternator charger, generator, or WAVE 3 you select, each with their own cables and documentation. A solar charging cable is needed for panels — if you're bringing third-party panels, check with us that you have the right MC4-to-XT60 cable.

EcoFlow DELTA 3 Classic: Frequently Asked Questions

Is 1024Wh enough for me?
It depends on what you're running and for how long. 1024Wh covers a weekend of phones, laptops, lights and a CPAP machine comfortably, or roughly 8 hours of a typical fridge cycling on and off. What it won't do is run air conditioning or electric heat for long, or back up a house through a multi-day outage. If either of those is your goal, the DELTA 3 Plus or a Max is the better starting point.
What can 1800W run?
A full-size refrigerator, a microwave, a coffee maker, a toaster, or most corded power tools — with a 3600W surge to cover motor startup. X-Boost extends resistive appliances to 2600W. As always, your total simultaneous draw has to stay within the rating.
How fast does it charge?
From a wall outlet, X-Stream charging gets it to 80% in 45 minutes at up to 1400W input. On 500W of solar a full charge takes about 2.5 hours. With the 500W alternator charger you'll see 80% in around 1.8 hours and a full charge in about 2.5 hours.
Which bundle makes the most sense?
If you'll mostly recharge from a wall outlet, the unit alone is the best value. For camping, the foldable 220W panel travels well. For an RV, van, or shed, the two rigid 100W panels are meant to be mounted and left. If you drive between locations, the 500W alternator charger is the fastest practical recharge. And for long outages with no sun, the Smart Generator 3000 starts and stops itself as needed.
Can it really run the WAVE 3 air conditioner?
It can power it, but not for long — an air conditioner is one of the heaviest loads you can put on a 1024Wh battery, so expect a couple of hours rather than a full night. The pairing works best for cooling a tent or van at bedtime, or alongside solar that keeps topping the battery up during the day. Call us at (303) 876-7654 and we'll estimate realistic runtime for your setup.
Can I use it as a UPS?
Yes. Switchover takes 10 milliseconds, which is fast enough to keep desktops, network gear, servers, and NAS systems running through a grid failure without a reboot.
Is the warranty really five years?
It's three years as standard, with two more added free when you register the unit in the EcoFlow app. Registration is quick and worth doing straight away, since the extra two years aren't applied automatically.
Can I leave it in the car or a cold garage?
It discharges from 14°F to 113°F but only charges from 32°F to 113°F, so below freezing it will still run your devices but won't accept a charge until it warms. A closed car in summer can exceed the upper limit, so don't leave it on a dashboard in direct sun.
How is it different from the DELTA 3 Plus?
The Classic is the smaller, lighter, less expensive unit in the DELTA 3 family. Step up to the Plus or Max and you gain capacity, higher continuous output, and more solar input. If your loads fit within 1800W and 1024Wh covers your runtime, the Classic saves real money — call us at (303) 876-7654 and we'll compare them against what you actually want to power.
Do you offer financing or price matching?
Yes. We offer 0% APR financing options through Affirm at checkout, and every purchase is backed by our Lowest Price Guarantee — if you find a better price elsewhere, call us at (303) 876-7654 before you order.
