Spec deltas
The Elite 320 costs $1,100 to the DELTA 2 Max's $1,049, and that $51 buys 1,152Wh. Work it out and the extra capacity lands at about 13 cents per added watt-hour, while the DELTA 2 Max's own storage costs 46 cents a watt-hour ($1,049 divided by 2,048Wh). Capacity is rarely on sale like that.
The DELTA 2 Max's case is watts and pounds. It runs 2,400W continuous with 4,800W of surge where the Elite 320 stops at 1,800W and 2,700W, and it weighs 50.7 lbs against 74.96. That's 600W of steady headroom and 24 pounds, and neither is a rounding error.
Three specs are identical: 3,000 cycles, a 5-year warranty, and a 1,000W solar ceiling on both. So there's no hidden longevity story here and no charging story. It's energy on one side, inverter and lift on the other, and $51 sitting in the middle.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
Divide each price into that and the Elite delivers a lifetime kilowatt-hour for 11 cents while the DELTA 2 Max charges 15. The box with the smaller sticker sells the more expensive electricity, and since the warranties match at 5 years, you aren't paying the difference for coverage either.
DELTA 2 Max: $1,049 for 2,048Wh, rated 3,000 cyclesElite 320: $1,100 for 3,200Wh, rated 3,000 cyclesBoth carry a 5-year warranty
Why it mattersIf you're comparing these on the $51, you're pricing the box instead of the energy that comes out of it.
That refill isn't free. Both accept the same 1,000W of solar, so topping the DELTA 2 Max back up means roughly two hours at a ceiling folding panels rarely reach, plus the panels themselves riding in the truck. The Elite takes about half again as long to fill from empty, which is real, but on a two-night trip it never gets there.
Weekend Camping load: 2,100WhDELTA 2 Max usable energy: 1,741Wh, or 85% of 2,048Wh after inverter lossesElite 320 usable energy: 2,720WhBoth units cap solar input at 1,000W
Why it mattersIf you camp two nights at a stretch without a panel kit, the DELTA 2 Max isn't the cheaper unit that weekend, it's the short one.
continuous output
Now look at where a big spike actually shows up. A tailgate spends 670Wh across a whole afternoon, a quarter of what the Elite can deliver, so capacity was never the binding constraint there. The griddle kicking on is. In exactly the situations where you're starting a motor or a compressor, the energy ask is small and the wattage ask is large, and that's the shape the DELTA 2 Max is built for.
DELTA 2 Max: 2,400W continuous, 4,800W surgeElite 320: 1,800W continuous, 2,700W surgeTailgate Party load: 670Wh, which is 25% of the Elite 320's usable energy and 38% of the DELTA 2 Max's
Why it mattersIf your hardest moment is a startup spike rather than a long night, buy the DELTA 2 Max; capacity you never reach isn't worth $51.
The awkward part is that the Elite 320's most decisive win is the camping trip, the one scenario here where somebody has to pick the thing up and carry it away from a wall outlet. Everything else it wins, it wins standing still: the outage, the workday, the overnight CPAP. A unit that lives on a shelf and rolls out twice a winter is carrying 75 lbs for free.
DELTA 2 Max: 50.7 lbsElite 320: 74.96 lbs, on oversized shock-absorbing wheels with a retractable telescoping handleB2The Elite 320 wins the stationary scenarios (8-Hour Blackout at 60% of usable, Remote Workday at 33%) and also the one you have to carry it to (Weekend Camping)
Why it mattersBuy the Elite 320 if it has a home; buy the DELTA 2 Max if it has a trunk.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: The capacity gap only counts if it changes an outcome, and it does: a 2,100Wh weekend load is 121% of the DELTA 2 Max's usable energy and 77% of the Elite 320's.
Four of the six scenarios go to the Elite 320, and only one of them goes there because of an outright failure. The DELTA 2 Max handles the blackout, the workday, the tailgate and the CPAP night perfectly well. It just handles them closer to empty. Weekend camping is the exception and it isn't close: a 2,100Wh trip against 1,741Wh of usable energy means the weekend ends before the battery finishes its job.
Van Life Daily is the honest one. A 4,685Wh day is 172% of the Elite 320's usable energy and 269% of the DELTA 2 Max's, and when both units are that far under, the bigger one isn't the answer, it's just the nearer miss.
Lifetime Value
Selected because: Both units are rated for 3,000 cycles, so lifetime cost is a pure capacity story: 11 cents per lifetime kWh for the Elite 320 against 15 cents for the DELTA 2 Max.
cost / lifetime kWh
Cost per warranty year flatters the DELTA 2 Max: $190 against $220, because the Elite 320 costs more up front and both warranties run 5 years. Cost per lifetime kilowatt-hour says the opposite, and that's the one worth acting on, because you bought a battery to move energy rather than to be under warranty.
The shelf price tells the same story more bluntly. The Elite 320's storage runs 34 cents a watt-hour ($1,100 divided by 3,200Wh), roughly a quarter less than the DELTA 2 Max charges for the identical unit of storage, and both boxes are rated to deliver it the same number of times.
What the Specs Don't Tell You
Selected because: This is where the DELTA 2 Max's counter-argument lives: 4,800W of surge against 2,700W, plus a noise figure BLUETTI doesn't publish at all.
The surge card is the DELTA 2 Max's best argument and it's a physical one. An inverter that runs 2,400W and briefly finds 4,800W will start motors that a 1,800W inverter with 2,700W of peak simply refuses, and a load that won't start is a load the Elite 320's 3,200Wh cannot help with. Capacity is patient. Watts are not.
Then the one nobody advertises: BLUETTI publishes no noise figure for the Elite 320. Unknown is not the same as quiet, and it's a fair thing to ask before a 75 lb box moves into a room you sleep in. EcoFlow at least commits to a published figure for the DELTA 2 Max, though reviewers still describe its fans getting loud under heavy load or while fast chargingA1, so treat any single number on either sheet as an idle-state promise rather than a working one.
Portability & Form Factor
Selected because: 50.7 lbs against 74.96 lbs decides this page for anyone whose unit doesn't get a permanent shelf.
weight
Fifty pounds is a suitcase you're mildly annoyed about. Seventy-five is a two-hands, bent-knees, wait-for-help lift, and the Elite 320 answers it with wheels and a telescoping handleB2 that solve flat ground and nothing else. Stairs are still stairs. A tailgate lip is still a tailgate lip.
So the real question isn't which is heavier, it's how often the thing moves. If it lives in a basement and comes out for outages, those 24 pounds cost you one afternoon of setup and then never again. If it rides to a campsite most weekends, you'll feel them on every single trip, and that is the DELTA 2 Max's strongest argument that has nothing to do with price.
Growth Path
Selected because: The DELTA 2 Max takes expansion batteries and the Elite 320 doesn't, but the DELTA starts 1,152Wh behind, so the first battery mostly buys back capacity the Elite already includes.
Expandability sounds like a free option and here it's mostly a refund. The DELTA 2 Max accepts expansion batteries and the Elite 320 doesn't, but the DELTA starts at 2,048Wh, so the first battery you add is largely buying back the 1,152Wh the Elite shipped with. The path only starts paying once you're past 3,200Wh.
Fixed capacity isn't a flaw when the fixed number is the larger one. The Elite 320's ceiling is real and you should check it against your longest unplugged stretch before you buy. It's just a ceiling that sits above the other unit's floor.

Weekend Camping
Two nights off-grid with essential comfort
Elite 320
2,100Wh over a weekend is 121% of what the DELTA 2 Max can actually deliver and 77% of the Elite 320's, so this one isn't a preference. The DELTA needs a recharge to finish the trip, and with both units capped at 1,000W of solar input that means panels in the truck and a couple of hours of real sun on Saturday.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Elite 320
Both units carry the 1,645Wh outage, but they carry it differently: the Elite 320 ends the night at 60% used and the DELTA 2 Max at 94%. One of those is a battery doing its job and the other is a battery finishing its shift. The Elite's 10ms switchover against 20ms is the tiebreak for anything without an internal battery of its own.

Either unit
320Wh is a rounding error for both of these: 12% of the Elite 320's usable energy, 18% of the DELTA 2 Max's. Neither wins on capacity, so break it on what you'd actually notice. If the machine travels with you, 50.7 lbs against 74.96 settles it. And BLUETTI publishes no noise figure for the Elite 320, which is worth asking about before a unit spends the night beside your head.

Both handle game day; the Elite 320 keeps more in reserve (25% used vs 38%). Tailgating is a light load, though, so the number you'll feel is weight: 50.7 lbs for the DELTA 2 Max against 75 lbs for the Elite 320, from the trunk to the setup spot.

Neither unit
Neither. A 4,685Wh day is 172% of the Elite 320's usable energy and 269% of the DELTA 2 Max's, and that gap is too wide for the bigger of the two to be the answer. Full-time daily draw wants a fixed house bank with alternator and rooftop solar charging, with a portable unit as the backup to it.

Conclusion
August 9, 2026
Verdict: the BLUETTI Elite 320
Take the Elite 320. An 8-hour outage runs it to 60% of its usable energy and runs the DELTA 2 Max to 94%, and the difference between those two is whether you go to bed watching the state of charge. It also switches over in 10ms against the DELTA's 20ms and pushes 140W out of USB-C against 100W, which is the unusual case of the cheaper-per-watt-hour unit also having the better ports. The carve-out is genuine and you should take it seriously: if anything in your house draws more than 1,800W, or the unit lives in a trunk rather than on a shelf, the DELTA 2 Max is the correct buy and the capacity gap is somebody else's problem.
At today's prices the Elite 320 is the cheaper unit ($936.25 against $1,049, with the Elite 320 $163.74 under its typical $1,099.99). At typical prices the DELTA 2 Max is ($1,049 against $1,099.99), and that is what the verdict weighs. Prices checked 1 day ago.

Each unit's star score is a category ranking, not customer reviews — no buyer opinions feed it. We score every station on size-independent quality (value, output, portability, endurance, ports, warranty, and more), then percentile-rank it against the other units in its capacity class, so a class-leading compact unit and a class-leading whole-home unit can both earn 5★. Here, DELTA 2 Max rates 3.8/5 (28th percentile of 26 Large-class units), and Elite 320 rates 4.0/5 (44th percentile of 26 Large-class units).
How the class ranking is computed →Test Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
24 Pounds Is the Whole Portability Story
74.96 lbs against 50.7 lbs, and 24 pounds is exactly the distance between a lift you do alone and one you plan. Flat ground is manageable. Basement stairs and a tailgate lip are not, and no handle changes that. If the unit gets a permanent spot near the breaker panel, the weight costs you one afternoon and then nothing at all. If it rides to a campsite, it costs you every trip.
Fixed at 3,200Wh, Which Is Still the Bigger Number
The Elite 320 can't grow, and here that matters less than it sounds. Its sealed ceiling sits 1,152Wh above the DELTA 2 Max's starting capacity, so the rival's expansion path spends its first battery catching up rather than pulling ahead. Fixed capacity is only a genuine cost if you'd pass 3,200Wh, and buyers who already know that should shop the next size up instead of planning to bolt on.
The Smaller Battery Has the Bigger Inverter
The DELTA 2 Max doubles its continuous rating when a motor kicks on: 4,800W of surge over 2,400W steady. The Elite 320 lifts to one and a half times, 2,700W over 1,800W. This is the one card that beats capacity outright, because a load that won't start is a load 3,200Wh can't help with. If nothing you own draws past 1,800W, it's a footnote. If something does, it's the whole page.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The Elite 320 is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The DELTA 2 Max is rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. If a computer with unsaved work is the thing being protected, the stated class is worth the attention; nothing here is a lab result.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The Elite 320's figure is a maximum rather than a guarantee — it depends on buying direct from BLUETTI or registering the unit, since reseller purchases carry a shorter term.
BLUETTI Won't Say How Loud It Is
There's no published noise figure for the Elite 320, and unknown is not the same as quiet. Every unit this size has fans, and they get busy when it's charging fast or working hard. If it's going in a bedroom, a home office, or anywhere within earshot of a desk, ask BLUETTI for a number before you commit rather than after.

Analyst note
The DELTA 2 Max is cheaper to buy, but the Elite 320 is cheaper to own. At $0.11/kWh over its lifetime vs $0.17/kWh, the Elite 320's higher cycle life and capacity make each dollar go further over the years. One thing to know reading the table: both carry the same 3,000-cycle rating, so the lifetime rows are sticker price and capacity in disguise — the wear horizon is identical and decides nothing here.
Brand trust
EcoFlow
Ecosystem
The deepest lineup in portable power, which is worth something concrete here: the DELTA 2 Max's expansion batteries and matching panels come from a catalogue that isn't going anywhere.
Support
US phone, email and chat, and the experience swings hard depending on who picks up. Plenty of hassle-free prepaid-label replacements, plenty of long waits and refurbished units sent against new claims. Buying through a retailer with a generous return window is the cheap hedge.

App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
Fastest-charging technology (X-Stream), deepest product ecosystem, and most active innovation cadence. At the very top of the range, the DELTA Pro Ultra platform stacks batteries and inverters into whole-home backup — a flagship path, not a line-wide feature.
Worth knowing
The practical caveat with EcoFlow: no parts or service once the 5-year warranty is up.
BLUETTI
Ecosystem
One of the broadest lineups — 15-20+ models from budget (AC2A) to flagship portable (Apex 300, 2764.8Wh). Includes specialized products: vehicle solar hubs, sodium-ion cold-weather units, and balcony storage systems.
Support
The least predictable support in the category, heavily email-based and running on a China timezone. Some claims go smoothly. Others turn into weeks of troubleshooting, or an offer of a discount on a new unit instead of a repair on the one you own. Buying direct rather than through a third party tends to go better.
Community
Active and growing — Reddit r/bluetti has a dedicated community. Second-largest after EcoFlow in engagement.
App experience
Rated 4.5/5 iOS and Android — tied for best app experience in the category. V3.0 UI redesign was well-received.
Unique strength
Watt-hours per dollar is the whole BLUETTI argument and the Elite 320 is a clean example of it. Worth being precise, though: both units on this page are rated for the same 3,000 cycles, so the value case here is capacity per dollar, not a longer life.
Worth knowing
Older BLUETTI units have gone unrepairable once parts stopped existing. That's a five-years-out risk rather than a first-year one, but it's the other side of the price.
Analyst note
EcoFlow sells access and BLUETTI sells watt-hours. Both warranties run 5 years, so the practical difference isn't the paper coverage, it's how hard it is to get someone to honor it. Weigh that against the $51 instead of treating it as free.

Analyst note
Don't read the DELTA 2 Max's expandability as a straight win here: it starts at 2,048Wh, below the Elite 320's 3,200Wh, so a first expansion battery largely buys back capacity the Elite 320 already includes. It only pulls ahead if you'd grow past 3,200Wh — short of that, the Elite 320's larger fixed capacity is the simpler value.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 2 Max
Field coverage on the DELTA 2 Max is mature and mostly kind. Reviewers put a full wall charge at roughly 80 minutes with 80% in about 50A2, and one six-month account found no structural degradation and a unit that still felt like day oneA3. The chemistry is the boring kind of good: LiFePO4 rated past 3,000 cycles to 80% with strong thermal behaviorA3.
The recurring complaint is the fans. Reviewers describe them getting loud under heavy load or while fast charging, with a quiet-charging mode that trades noise for time and a suggestion to leave about six inches of clearance for airflowA1. The overall read stays positive with caveats rather than enthusiasticA4.
“Fast AC wall charging — 0 to 80% in about 50 minutes and a full charge in roughly 80 minutes.”

BLUETTI Elite 320
The Elite 320 is new, so what exists is launch and first-look coverage rather than long-term ownershipB1B4.

On what the capacity buys, reviewers cite over 66 hours of refrigeration, roughly two days of household essentials, across four AC outlets, two USB-A and two USB-C at 140W and 100WB3. Read that as launch-material arithmetic rather than a measured result. Nobody has owned one through a winter yetB1B4.

- →Something you own draws more than 1,800W. The Elite 320 stops there; the DELTA 2 Max keeps going to 2,400W and finds 4,800W the instant a compressor kicks on.
- →The unit lives in your trunk. 50.7 lbs is a one-person lift over a tailgate. 74.96 lbs is a conversation with whoever came with you.
- →You need it back to full between uses rather than overnight: a full wall charge lands around 80 minutes, 80% in about 50A2.
- →You want a starter unit that can eventually grow past 3,200Wh, and you've accepted that the first expansion battery mostly catches you up rather than pulling you ahead.
Buy the Elite 320 if you…
- →The power goes out a few times a winter and the unit lives on a shelf in between. An 8-hour outage uses 60% of what it can deliver, so you go to bed without doing math.
- →You camp two nights at a time and don't want to bring panels just to make the trip work: 2,100Wh is 77% of the Elite 320's usable energy.
- →You want the desktop, the router and the NAS to ride through a flicker. 10ms of switchover against 20ms, and 140W out of one USB-C port for the laptop.
- →You're buying watt-hours per dollar and want the cheapest lifetime energy on this page, at 11 cents per kWh.
If neither fits
Van life is out for both. A 4,685Wh day is 172% of the Elite 320's usable energy and 269% of the DELTA 2 Max's, and full-time daily draw at that level wants a fixed house bank with alternator and rooftop charging, with a portable box as the backup to that system rather than the system. And if a CPAP is genuinely the whole job, you'd be using 12% of the Elite or 18% of the DELTA on a 320Wh night: buy a unit a fraction of this size and put the savings into panels.
The Bottom Line
Take the Elite 320. Both units are rated for 3,000 cycles and both are covered for 5 years, so the entire difference between them is how much energy each one holds and what that energy costs, and the Elite wins it at 11 cents a lifetime kilowatt-hour against 15. It also finishes the two-night camping weekend the DELTA 2 Max can't.
The one reason to close this tab and buy the DELTA 2 Max is a ceiling you'll actually hit. If something in your house draws past 1,800W, or the box spends its life going in and out of a trunk, then 600W of inverter and 24 fewer pounds beat 1,152Wh you'd rarely reach. Everyone else is buying watt-hours, and the Elite 320 sells them cheaper.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the BLUETTI Elite 320 worth $51 more than the EcoFlow DELTA 2 Max?
Yes, if you're buying energy. That $51 buys 1,152Wh, about 13 cents per added watt-hour, and it drops lifetime cost from 15 cents per kWh to 11 because both units are rated for the same 3,000 cycles. The one case where it isn't worth paying is a load over 1,800W, which the Elite 320 can't run at any price.
Can the Elite 320 run a microwave or a space heater?
Only if the appliance draws under 1,800W, which is where its inverter stops. Brief peaks are covered to 2,700W, so a motor that spikes past that will trip it. The DELTA 2 Max runs 2,400W continuous with 4,800W of surge, and that 600W of steady headroom is the whole reason to pick the smaller battery.
Which one is better for a power outage?
The Elite 320. A 1,645Wh outage leaves it at 60% of its usable energy while the DELTA 2 Max finishes at 94%, and it switches over in 10ms against 20ms, which matters for a desktop or anything without a battery of its own. The catch is 74.96 lbs, which is fine as long as the unit already sits where you need it.
How fast does each one recharge?
Off the wall the DELTA 2 Max is the quick one: reviewers report a full charge in about 80 minutes and 80% in roughly 50. Off solar they share a 1,000W ceiling, so the DELTA needs about two hours of full-strength input to refill 2,048Wh and the Elite 320 about half again as long for 3,200Wh. Real panels rarely hit that ceiling, so treat both as best cases.
Does the DELTA 2 Max's expandability close the capacity gap?
Eventually, but not efficiently. It starts 1,152Wh below the Elite 320, so the first expansion battery is mostly buying back capacity the Elite ships with in the box. Expansion only pays off once you're headed past 3,200Wh, and if you already know that's you, buy for the number you're headed to rather than planning to bolt on.
