EcoFlow DELTA 2 Max Portable Power Station (2048Wh)

The DELTA 2 Max delivers 2400W of continuous output with a 4800W surge and X-Boost to 3400W — enough for a full-size fridge, a microwave, or most corded power tools. 2048Wh of LFP capacity expands to roughly 6kWh with two extra batteries.

Its LFP cells are rated for 3000 cycles to 80% capacity, which EcoFlow puts at about six times the life of comparable lithium-ion power stations, and it's around 30% lighter than similar-capacity units. X-Stream charging takes 1800W from a wall outlet, and two solar ports accept up to 1000W combined. Renewable Outdoors is an authorized EcoFlow dealer.

Why the DELTA 2 Max

2400W, 4800W Surge

Runs 99% of household appliances — a fridge, a microwave, power tools — with X-Boost extending to 3400W.

6× the Cycle Life

LFP cells rated 3000 cycles to 80% capacity — around six times what comparable lithium-ion power stations manage.

Expands to About 6kWh

Takes up to two DELTA 2 Max or DELTA Max Smart Extra Batteries, so runtime can triple later without replacing anything.

1000W of Solar

Two solar ports at 500W each across an 11–60V range — substantial solar capacity for a unit this size.

1800W X-Stream Charging

Fast mains charging, and it also accepts car charging and the 800W alternator charger for recharging while you drive.

30% Lighter, One-Piece Build

50 lbs and a sturdy one-piece shell — noticeably lighter than similar-capacity units despite the LFP battery.

Building Your Configuration

This listing combines two independent choices into fifteen configurations. Rather than list all fifteen, here's what each choice does.

Choice Your Options What It Changes How to Decide
Extra Batteries None, 1, or 2 DELTA 2 Max Smart Extra Batteries Stored energy — how long you run. Output stays at 2400W regardless Add batteries if outages in your area last more than a few hours, or you're off-grid for days at a time
Solar Panels None, 1–2 × 220W, or 1–2 × 400W How fast you refill without mains power, up to the unit's 1000W solar ceiling Two 400W panels (800W) get closest to the ceiling and give the fastest recharge; a single 220W is a light top-up

Two things worth knowing before you choose. Extra batteries and solar solve different problems — batteries extend how long you can run, while solar removes your dependence on a wall outlet. If you're preparing for outages, batteries matter more; if you're camping off-grid, solar does. And between the panel options, the 400W bundle gives you the fastest recharge, while the 220W bifacial panel is lighter to carry and quicker to set up. Call us at (303) 876-7654 and we'll help you weigh it up for your situation.

EcoFlow DELTA 2 Max

In the Box

  • EcoFlow DELTA 2 Max power station

EcoFlow DELTA 2 Max: Frequently Asked Questions

Should I add extra batteries or solar panels?
They solve different problems. Extra batteries extend how long you can run — useful for outages lasting more than a few hours. Solar panels remove your dependence on a wall outlet — useful for camping and off-grid stays. If you're preparing for storms, batteries matter more; if you're travelling, solar does. Adding neither is fine too, since the DELTA 2 Max charges from mains at 1800W.
What can 2400W run?
A full-size refrigerator, a microwave, a coffee maker, or most corded power tools, with a 4800W surge for motor and compressor startup. X-Boost extends resistive appliances to 3400W. Your total simultaneous draw still has to stay within the rating.
How long will 2048Wh last?
Roughly 24 hours for a typical fridge cycling on and off, or about two hours for a 1000W space heater. A CPAP machine will run for several nights. Two extra batteries take total capacity to about 6kWh, which puts multi-day essential-load backup within reach.
How much solar can I connect?
Up to 1000W, split across two ports rated 500W each over an 11–60V range. That means two 400W panels (800W) is the closest the bundles get to the ceiling, and there's still room to add more later.
Which extra batteries fit?
Up to two DELTA 2 Max Smart Extra Batteries, and EcoFlow also lists the older DELTA Max Smart Extra Battery as compatible. If you already own a DELTA Max battery, call us at (303) 876-7654 before buying a new one — there's a good chance it carries over.
Why choose LFP over cheaper lithium-ion?
Cycle life. These cells are rated for 3000 cycles to 80% capacity, which EcoFlow puts at about six times what comparable lithium-ion power stations achieve. If you'll cycle the unit regularly rather than leave it on a shelf, that difference dominates the value calculation.
Can I recharge it while driving?
Yes, two ways. Standard car charging works from a 12V or 24V socket at 8A, and the DELTA 2 Max is also compatible with EcoFlow's 800W Alternator Charger, which is dramatically faster — roughly 1kWh in 1.3 hours. For road trips and overlanding, the alternator charger is the one that makes a real difference.
How does it compare to the DELTA 3 Max?
Both hold 2048Wh with 2400W output and a 4800W surge. The DELTA 3 Max is the newer generation and slightly lighter at 44.8 lbs against 50, but it isn't expandable — no extra batteries. The DELTA 2 Max takes up to two, reaching about 6kWh. If future expansion matters, that's the deciding factor.
Can it back up my house?
It powers whatever you plug directly into it, which covers a fridge, lights, internet, and devices during an outage. It isn't designed to feed your breaker panel. For backup through your home's wiring you'd want a DELTA Pro 3 or a DELTA Pro Ultra system with a transfer switch or smart home panel — call us at (303) 876-7654 and we'll point you to 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.
