Model: DELTA 3 Max Only (ETA Mid August)
2048Wh · 2400W Output · 0–80% in 68 Minutes · 13% Lighter

EcoFlow DELTA 3 Max Portable Power Station (2048Wh)

The DELTA 3 Max doubles the Classic's capacity to 2048Wh while adding output — 2400W continuous with a 4800W surge, and X-Boost to 3400W for resistive appliances. It's the middle of the DELTA 3 range: enough for a fridge, a microwave, and your electronics through a long outage, without the weight and cost of the Ultra tier.

EcoFlow rebuilt it to be 13% lighter than its predecessor, using LFP cells in an EV-grade structure, and it recharges from a wall outlet to 80% in 68 minutes. Four charging methods, 10ms UPS switchover, and about 25dB at 600W. Renewable Outdoors is an authorized EcoFlow dealer — call us and we'll tell you honestly whether the Max or the Max Plus is the better buy for you.

Why the DELTA 3 Max

2400W, 4800W Surge

Pure sine wave output for a full-size fridge, a microwave, or power tools, with surge headroom for compressor and motor startup.

2048Wh of LFP

Double the Classic's capacity in the same family — enough to keep a fridge, lights, and internet going through a long outage.

X-Boost to 3400W

Runs resistive appliances rated well above the inverter's continuous output — a kettle, a hair dryer, a heat gun.

0–80% in 68 Minutes

Straight from a wall outlet — no generator or special hardware required to get the headline charge time.

13% Lighter Than Before

EcoFlow trimmed roughly an eighth of the weight off the previous generation while keeping the LFP cells and EV-grade structure.

10ms Switchover, ~25dB

Fast enough to serve as a UPS for a computer or NAS, and quiet enough to sit in a living space while it works.

Choose Your Configuration

Configuration Solar or Charger Added Why Choose It
DELTA 3 Max Only None Home backup and travel power where a wall outlet is your normal recharge — and at 68 minutes to 80%, that's genuinely fast
+ 2 × 220W Solar Panels 440W of foldable panels Camping and off-grid — two lighter panels you can angle separately to follow the sun or dodge shade
+ 400W Solar Panel 400W in one panel Simpler setup with a single panel and one cable, at the cost of being heavier to carry
+ 500W Solar Panel 500W in one panel Matches the unit's 500W solar ceiling exactly — the fastest solar recharge available for this model
+ 500W Alternator Charger The 500W alternator charger Vanlife and overlanding — recharges from your engine while you drive, far faster than a 12V socket

This unit accepts a maximum of 500W of solar, so the 500W panel bundle uses that ceiling exactly and the 2 × 220W option slightly exceeds it — extra panel capacity isn't wasted, it just means you reach the 500W limit earlier on an overcast day. The trade-off between the single-panel and two-panel options is handling rather than power. Call us at (303) 876-7654 if you'd like a second opinion on your setup.

What's Included

EcoFlow DELTA 3 Max

In the Box

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

Bundle configurations add the solar panels or alternator charger you select, with their own cables and documentation. Solar panels need a solar charging cable — if you're using third-party panels, check with us that you have the correct MC4-to-XT60 cable.

EcoFlow DELTA 3 Max: Frequently Asked Questions

How is this different from the DELTA 3 Max Plus?
Both hold 2048Wh, but the Max Plus is the stronger unit: 3000W continuous and a 6000W surge against this one's 2400W and 4800W, X-Boost to 3800W instead of 3400W, and 1000W of solar input instead of 500W. The Max Plus also expands to 10kWh with extra batteries, which the Max doesn't. If your loads fit inside 2400W and you don't need expansion, the Max saves real money for the same stored energy.
What can 2400W run?
A full-size refrigerator, a microwave, a coffee maker, or most corded power tools, with a 4800W surge to absorb motor and compressor startup. X-Boost extends resistive appliances like kettles and hair dryers to 3400W. Your total simultaneous draw still has to stay within the rating.
How long will 2048Wh last?
Divide 2048Wh by your load. A 150W fridge cycling at roughly 50% duty runs around 24 hours; a 1000W space heater lasts about two; a CPAP machine will go for several nights. That makes it a realistic choice for a full day or two of essential loads.
How fast does it charge?
0 to 80% in 68 minutes from a standard wall outlet — worth noting because it doesn't need a generator or special hardware to hit that figure, unlike some larger units in the range. Solar, car, and alternator charging are also supported.
How much solar can I connect?
Up to 500W. The 500W panel bundle uses that ceiling exactly. The 2 × 220W bundle totals 440W, and adding more panel capacity than 500W isn't harmful — it just means you reach the input limit sooner on a cloudy day rather than gaining peak speed.
Can I add an extra battery?
No — the DELTA 3 Max isn't an expandable model. If growing capacity later matters to you, the DELTA 3 Max Plus expands to 10kWh and the DELTA 3 Ultra to 11kWh. Call us at (303) 876-7654 before you buy if you think you'll want more capacity down the line.
Can I use it as a UPS?
Yes. Switchover takes 10 milliseconds, fast enough to keep desktops, network equipment, and NAS systems running through a grid failure without rebooting.
Is it quiet enough for a living room?
EcoFlow rates it at 25dB or less at 600W, which is around library quiet. Under heavy load or fast charging the fans work harder and it becomes noticeably louder, so consider a hallway or utility room if you're charging overnight.
Is the warranty really five years?
Three years as standard, with two more added free when you register the unit in the EcoFlow app. Registration takes a couple of minutes — do it when the unit arrives, because the extra cover isn't applied automatically.
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.
