Model: DELTA 3
1024Wh · 1800W Output · Full Charge in 56 Minutes · IP65 Battery Pack

EcoFlow DELTA 3 Portable Power Station (1024Wh)

The DELTA 3 covers 99% of household devices — a fridge, a TV, computers, power tools — with 1800W of continuous output and a 3600W surge, and X-Boost carries appliances past 2200W. Thirteen output ports means you rarely run out of somewhere to plug in.

What sets it apart in this size class is how fast it refills and how long it lasts: 1500W AC input takes it 0–100% in 56 minutes, 500W of solar does it in two hours, and 800W car charging in 1.3. The third-generation LFP cells are rated for 4000 cycles to 80% capacity — about ten years, and roughly 25% above the industry norm. It runs at 30dB and the battery pack is IP65 rated. Renewable Outdoors is an authorized EcoFlow dealer.

Why the DELTA 3

0–100% in 56 Minutes

1500W X-Stream AC charging fills it completely inside an hour — and 30 minutes of charging buys hours of backup if a storm is coming.

4000 Cycles to 80%

Third-generation LFP cells rated for about ten years of use — roughly 25% beyond the industry standard for this class.

13 Output Ports

Six AC outlets, two USB-C at 100W, two fast-charge USB-A, a 126W car port, and two DC5521 outputs for lights and small DC gear.

Expands to 5kWh

Takes DELTA 3, DELTA Pro 3, DELTA 2 Max, or DELTA 2 extra batteries — unusually flexible if you already own EcoFlow gear.

X-Boost Past 2200W

Runs ovens, hair dryers, and kettles rated above the inverter's continuous output rather than refusing them outright.

30dB and IP65 Cells

Effectively inaudible under 600W, with an IP65-rated battery pack — a real advantage for RV and outdoor use.

Choose Your Configuration

Configuration What It Adds Why Choose It
DELTA 3 The power station on its own Home backup and travel where a wall outlet is your recharge — and at 56 minutes to full, that's genuinely quick
+ 110W Portable Solar Panel 110W foldable panel The lightest and most packable solar option — easiest to carry on foot
+ 160W Portable Solar Panel 160W foldable panel 45% more solar than the 110W panel for very little extra bulk — the sensible middle option
+ 220W Portable Solar Panel 220W bifacial foldable panel A serious camping setup — recharges meaningfully faster and the bifacial design picks up reflected light
+ 400W Portable Solar Panel 400W foldable panel Closest to the unit's 500W solar ceiling — the fastest solar recharge, for off-grid stays without mains
+ DELTA 3 Extra Battery One DELTA 3 extra battery Doubles stored energy for multi-day outages — runtime rather than recharge speed
+ Smart Generator 3000 Smart Generator 3000 (dual fuel) Long outages with no sun — it starts and stops itself as the battery needs topping up

Worth knowing before you pick a solar bundle: this unit accepts up to 500W of solar, so even the 400W bundle leaves headroom to add a panel later. Between the smaller options, more panel means faster recharging and better output in poor light — the trade-off is weight and pack size. Call us at (303) 876-7654 if you'd like help matching a panel to how you'll actually use it.

What's Included

EcoFlow DELTA 3

In the Box

  • EcoFlow DELTA 3 power station
  • AC charging cable
  • User manual and warranty card

Bundle configurations add the solar panel, extra battery, or generator you select, with their own cables and documentation. Solar panels need a solar charging cable — if you're bringing third-party panels, check with us that you have the right MC4-to-XT60 cable.

EcoFlow DELTA 3: Frequently Asked Questions

How is the DELTA 3 different from the DELTA 3 Plus and DELTA 3 Classic?
All three hold 1024Wh and deliver 1800W with a 3600W surge, so they run the same appliances. The differences are in charging and ports. The DELTA 3 takes 500W of solar and charges to full in 56 minutes on AC. The Plus doubles solar input to 1000W across two ports, upgrades USB-C to 140W and USB-A to 36W, and pushes X-Boost to 2600W. The Classic is the simpler, cheaper unit. If you'll recharge from solar, the Plus is worth it; if you charge from the wall, the DELTA 3 or Classic saves money.
What can 1800W run?
EcoFlow reckon it covers 99% of household devices — a full-size fridge, a TV, computers, a microwave, most corded power tools — with a 3600W surge for motor startup. X-Boost carries appliances past 2200W, including ovens around 2150W, hair dryers, and kettles. Total simultaneous draw still has to stay inside the rating.
How long will 1024Wh last?
Around 8 hours for a typical fridge cycling on and off, a full weekend of phones, laptops, and lights, or several nights for a CPAP machine. A 1500W space heater will flatten it in well under an hour. Adding an extra battery doubles it, and the system takes you to 5kWh.
Which extra batteries does it accept?
Unusually flexible for this class: DELTA 3, DELTA Pro 3, DELTA 2 Max, and DELTA 2 extra batteries all work, up to a 5kWh total. If you already own an older EcoFlow extra battery, there's a good chance it carries over — call us at (303) 876-7654 and we'll confirm before you buy anything.
How fast does it really charge?
0 to 100% in 56 minutes at 1500W from a normal wall outlet — no generator or accessory needed. Solar at 500W takes about two hours, and 800W car charging about 1.3 hours. EcoFlow also notes that just 30 minutes on AC gives you hours of backup, which matters when a storm warning arrives at short notice.
How long will the battery last before it wears out?
EcoFlow rates the third-generation LFP cells at 4000 cycles to 80% or more of original capacity — about ten years of regular use, and roughly 25% above the industry standard for this class. That's the figure worth comparing when you're weighing this against a cheaper power station.
Can I use it in an RV or outdoors in the rain?
The battery pack carries an IP65 rating, which is genuinely useful for RV and outdoor use, but that rating covers the pack rather than the whole unit with its ports and screen. Treat it as splash-tolerant rather than weatherproof — keep it under cover in sustained rain.
Is it quiet enough to sleep next to?
Under 600W of load it runs at about 30dB, which blends into ambient room noise — EcoFlow specifically rate it as suitable for a tent or bedroom. Push it hard or fast-charge it and the fans become clearly audible, so a hallway is better for an overnight 1500W charge.
Can it power my house during an outage?
It powers whatever you plug directly into it, which covers a fridge, lights, internet, and devices. It isn't designed to feed your breaker panel. For backup through your home's wiring you'd want a DELTA 3 Ultra with a transfer switch, or a DELTA Pro 3 or DELTA Pro Ultra system. Call us at (303) 876-7654 and we'll point you at the right tier.
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.
