Head-to-head test
EcoFlow DELTA Pro Ultra vs Jackery Explorer 1500 v2
Five Explorer 1500 v2s would beat the DELTA Pro Ultra on both watt-hours and weight, so the $3,250 between these two isn't buying stored energy. It's buying one circuit big enough for a compressor and fast enough that nothing blinks.

Spec deltas
$949 against $4,199 isn't a comparison, it's a fork in the road. The Explorer 1500 v2 is a 32-lb box you carry in one hand. The DELTA Pro Ultra is a 181.8-lb, 7,200W system with a 0ms handoff that you site once and then leave alone. Four times the battery (6,144Wh against 1,536Wh), nearly six times the price, and almost nothing shared between them.
The people who land on a page like this usually haven't picked a class yet. They've decided they want backup power and they're bracketing the range, cheap end against serious end, to see which one feels like the right amount of money. So the useful question isn't which unit is better. The DELTA Pro Ultra is better at nearly everything measurable. The question is whether you're buying a battery you carry or infrastructure you install.
Here's the test that settles it. Of the six loads modelled on this page, the Explorer covers three outright and misses three, and one of the misses is the eight-hour blackout. If your night is on the first list, take the Jackery and spend the $3,250 difference on panels, a better fridge, or the trip itself. If it's on the second, no amount of value math rescues a battery that runs out at hour six.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Watt-hours are the cheap part of this decision. What five boxes can't do is present a single 7,200W circuit or hand over in 0ms. They're five islands, each capped at 2,000W with a 20ms transfer, and no amount of stacking merges them. The premium buys one big circuit that never blinks.
DELTA Pro Ultra: $4,199 for 6,144Wh, 181.8 lbsExplorer 1500 v2: $949 for 1,536Wh, 32 lbsDELTA Pro Ultra: 7,200W continuous with 0ms switchover; Explorer 1500 v2: 2,000W continuous with 20ms switchover
Why it mattersIf you can't name a load above 2,000W or a device that would notice a 20ms gap, the $3,250 is buying you something you'll never switch on.
A second Explorer fixes the energy for $1,398 total and puts 2,612Wh usable on the board, which clears both the blackout's 1,645Wh and the weekend's 2,100Wh. What it doesn't fix is that two units are two islands. You're hand-splitting the fridge onto one and the router onto the other, and neither one gets past 2,000W.
8-Hour Blackout models 1,645WhExplorer 1500 v2 usable capacity: 1,306Wh (1,536Wh derated 15% for inverter losses)Explorer 1500 v2 price: $949 each
Why it mattersIf outage backup is why you're shopping, buy enough for the whole outage in one unit. The two-box workaround genuinely works, but you're doing the load management yourself at 2am.
solar input
That inverts the intuition that a small battery is the quick one to top up, and it decides the off-grid case outright. A 4,685Wh day needs a battery that holds it, which the Explorer's 1,306Wh usable does not, and an input path that can put it back before dark. 400W is not that path.
DELTA Pro Ultra: 5,600W solar input against 6,144Wh capacityExplorer 1500 v2: 400W solar input against 1,536Wh capacityVan Life Daily models 4,685Wh per day
Why it mattersAnyone planning to live off solar rather than top up at a campground or a wall socket should read the input rating before the capacity rating.
A compressor surges against an absolute wattage, not a multiplier. The Explorer's hard maximum of 4,000W sits below the DELTA Pro Ultra's 7,200W continuous rating, which means the EcoFlow starts big loads without even leaving its normal operating range. Owners describe its inverter running a 3-ton central ACA4.
DELTA Pro Ultra: 7,200W continuous, 10,800W surgeExplorer 1500 v2: 2,000W continuous, 4,000W surge
Why it mattersAnyone sizing for a well pump, a compressor or a shop tool should read the surge ceiling and ignore the ratio, because the ratio always flatters whichever inverter is smaller.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Every load here is decided by one number: the Explorer's 1,306Wh usable against the DELTA Pro Ultra's 5,222Wh. Three of six modelled scenarios fit under the smaller ceiling and three don't.
The Explorer's real ceiling is 1,306Wh: 1,536Wh nameplate, derated 15% for inverter losses. Every scenario on this page turns on that single figure. Three of six modelled loads land under it and three land over, and over is a wall rather than a slope. The DELTA Pro Ultra's equivalent number is 5,222Wh, which is why it clears all six without thinking about any of them.
The eight-hour blackout is the one worth staring at, because it's the reason most people buy these at all. It models 1,645Wh; the Explorer holds 1,306Wh usable, about 79% of it, so at the modelled average draw you get roughly six and a half hours and then the fridge is on its own. The DELTA Pro Ultra spends 31% of its usable capacity on the same night. Both of those are accurate descriptions of one outage, and they produce completely different Tuesdays.
Portability & Form Factor
Selected because: 32 lbs against 181.8 lbs decides whether this goes camping with you or lives beside the breaker panel, and it outranks spare headroom in half the scenarios on this page.
weight
32 lbs is a one-hand carry from the trunk to the picnic table. 181.8 lbs is a two-person lift you perform once, in a spot you've already committed to, and then never again. That isn't a line on a spec sheet, it's the whole question of whether the unit comes with you or waits at home for you to come back.
It matters most in the scenarios where the EcoFlow wins on paper and the win means nothing. Tailgating draws 670Wh: 13% of the DELTA Pro Ultra's usable capacity, 51% of the Explorer's. Both cover it comfortably, so the only number that changes your afternoon is the one you carry across the parking lot.
Lifetime Value
Selected because: $0.11 per lifetime kWh against $0.19, driven by the Explorer's 4,000-cycle rating beating the EcoFlow's 3,500. That only counts if you actually spend the cycles.
cost / lifetime kWh
Eleven cents a lifetime kilowatt-hour against nineteen. The Explorer is the cheaper unit to own, and the reason is the part nobody expects: the $949 box is rated for 4,000 cycles and the $4,199 one for 3,500. Cheap and long-lived usually don't travel together, and here they do.
That metric assumes you spend the cycles, though, and a backup unit rarely gets the chance. At a full cycle every day the DELTA Pro Ultra's rated life runs 9.6 years. A unit that sits in a closet waiting for three outages a year will still be a few hundred cycles in when the warranty runs out. For that buyer the honest number isn't cents per kWh at all. It's the sticker: $400 per warranty year on the EcoFlow against $140 on the Jackery, and $3,250 that stays in your account either way.
What the Specs Don't Tell You
Selected because: The 0ms against 20ms handoff and the surge ceilings (10,800W against 4,000W) explain the $3,250 price gap far better than capacity does.
rated cycles
Two specs explain the price gap better than capacity does, and the first is switchover: 0ms against 20ms. The DELTA Pro Ultra is a true online UPS, so the load sits on battery permanently and there is no transfer to ride through. The Explorer is a standby unit that hands over in up to 20ms. A lamp, a fridge and a laptop will never know it happened. A desktop mid-render, a network rack, or gear with a fussy power supply might.
The second is surge, and it's the one place the spec sheet flatters the small unit. The Jackery doubles its continuous rating to 4,000W while the EcoFlow adds only half again, to 10,800W. Better ratio, much worse ceiling, and compressors don't care about ratios. The Explorer's absolute surge maximum sits below the number the DELTA Pro Ultra holds all day.
Growth Path
Selected because: The Explorer is sealed at 1,536Wh and the DELTA Pro Ultra accepts expansion batteries, but the EcoFlow's base 6,144Wh already exceeds the Jackery's ceiling four times over.
solar input
The Explorer is sealed at 1,536Wh, and that is not the mark against it. Expansion only counts when what you'd expand into beats the rival, and the DELTA Pro Ultra's starting 6,144Wh is already four times the Jackery's entire ceiling. The expansion batteries are a footnote to a decision that base capacity settled before you got here. Buy the Explorer for the load you have this year; if you're planning around a load you'll have in two, the problem is the price bracket, not the chassis.

Scenario verdicts
We ran the math on six real-world scenarios. Here's which unit survives your actual life.
SCN-01 · 2 nights · needs 2,100Wh
Weekend Camping
Two nights off-grid with essential comfort
Neither unit
A weekend draws 2,100Wh and the Explorer holds 1,306Wh usable, so it covers about 62% of the trip and you finish on the car charger. The DELTA Pro Ultra spends 40% of its usable capacity on the same weekend and comes home nearly full. Buy the Jackery for this only if you're bringing solar or shortening the trip.

8-Hour Blackout
Keep the essentials running through a night without power
DELTA Pro Ultra
1,645Wh of essentials over eight hours, against the Explorer's 1,306Wh usable. That's about 79% of the night, so roughly six and a half hours at the modelled average draw before the fridge is on its own. The DELTA Pro Ultra spends 31% of its usable capacity and never notices. This is the scenario that justifies the price gap, if anything does.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
Both cover this one and neither breaks a sweat: 320Wh against 1,306Wh usable on the Jackery and 5,222Wh on the EcoFlow, so 25% and 6%. They're rated in the same noise band, so that doesn't separate them either. The tiebreak is $949 and 32 lbs against $4,199 and 181.8 lbs, and on a load this small that isn't a hard call.

Both units cover a 910Wh workday, and the DELTA Pro Ultra takes the scenario on margin: 17% of its usable 5,222Wh against the Explorer's 70% of 1,306Wh. That margin is worth real money if your day sometimes runs long or a second device shows up mid-afternoon. It's worth nothing if every workday looks like the last one.

Both handle game day. 670Wh is 51% of the Explorer's usable capacity and 13% of the DELTA Pro Ultra's, so the EcoFlow takes it on headroom. Headroom is the wrong metric in a parking lot, though. 32 lbs against 181.8 lbs is the one you feel, and you feel it for the length of the walk.

DELTA Pro Ultra
4,685Wh a day is where the Explorer stops being a candidate. It holds 1,306Wh usable, under a third of the day. The DELTA Pro Ultra covers it, but read the margin before celebrating: that's 90% of its usable 5,222Wh, leaving 537Wh.

Conclusion
August 9, 2026
Verdict: the Jackery Explorer 1500 v2
Buy the Explorer 1500 v2. It's $949 against $4,199, 32 lbs against 181.8, and it carries a higher cycle rating (4,000 against 3,500) than the unit costing nearly six times as much. Of the six loads modelled here it covers three outright: the CPAP night at 25% of its usable capacity, the remote workday at 70%, the tailgate at 51%. Those are the loads most people shopping a portable actually have. The DELTA Pro Ultra is the far more capable machine and it becomes the right answer the moment your need is real: a load above 2,000W, gear that can't survive a 20ms transfer, or a day that draws more than the Explorer's 1,306Wh usable. If none of those describe you, the extra $3,250 buys capacity you will never spend.

See the full weight table and data sourcing on our methodology page →Class ranking (the star rating)
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 Pro Ultra rates 4.9/5 (93rd percentile of 16 Home Backup-class units), and Explorer 1500 v2 rates 3.8/5 (27th percentile of 27 Everyday-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.
181.8 lbs Is a Siting Decision, Not a Carry
This is a two-person lift and realistically a one-time one. You choose where it lives and it lives there. The Explorer 1500 v2 at 32 lbs goes into the trunk with one hand and comes out the same way. If the unit needs to move more than twice a year, that difference outranks every other line on this page, including the four-to-one capacity gap.
Fixed at 1,536Wh, and That Isn't the Flaw
The Explorer can't grow, but sealed isn't the mark against it here. Expansion only matters when what you'd expand into beats the rival, and the DELTA Pro Ultra's starting 6,144Wh is already four times the Jackery's whole ceiling. Size the Explorer for the load you have. If you're buying against a load two years out, the issue is the price bracket, not the chassis.
The Better Ratio Belongs to the Weaker Inverter
The Explorer doubles its continuous rating on surge, 2,000W to 4,000W. The DELTA Pro Ultra only adds half again, 7,200W to 10,800W. That reads as a Jackery win until you remember that compressors surge against an absolute number: the Explorer's hard ceiling of 4,000W sits below the EcoFlow's continuous rating. Read the ceiling, not the multiplier.
0ms vs 20ms Is a Class Difference, Not a Spec Bump
The DELTA Pro Ultra runs as a true online UPS, so the load sits on battery permanently and there is no transfer to ride through. The Explorer 1500 v2 is a standby unit that hands over in up to 20ms. A fridge, a lamp and a laptop will never know. A desktop mid-save, a network rack, or gear with a picky power supply might, and that's the entire buyer profile for the more expensive unit.
Ten Years vs Five, and the Cycle Ratings Disagree
EcoFlow warranties the DELTA Pro Ultra for 10 years to Jackery's 5, yet rates it for fewer cycles: 3,500 against the Explorer's 4,000. Priced out, that's $400 per warranty year against $140. Longer coverage on the expensive unit is worth having. It isn't worth $3,250 on its own, and the cycle numbers say the cheaper cells are the longer-lived ones.

Analyst note
The Explorer 1500 v2 wins on both sticker price and long-term value. At $0.15/kWh over its lifetime, it's meaningfully cheaper to own. Clear value winner. One caution on the lifespan row: the Explorer 1500 v2 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the DELTA Pro Ultra still delivers more over its shorter horizon (21,504 vs 6,144 kWh). Years measure wear, not usefulness.
Brand trust
EcoFlow
Ecosystem
The deepest catalogue in portable power, 12-15 models across DELTA Pro, DELTA 3 and RIVER 3 plus panels and smart home panels. That matters more than usual here, because the DELTA Pro Ultra is the one unit on this page designed to be part of a system rather than a standalone box.
Support
US phone, email and chat, with genuinely split outcomes: plenty of hassle-free prepaid-label replacements, and plenty of long waits and refurbished units sent against claims on new hardware. Buying through Costco or Amazon adds a return window that costs you nothing.
Community
Largest community in the space — Reddit r/Ecoflow_community (~31K members), multiple Facebook groups, and an official community forum
App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
X-Stream fast charging and modular expansion are the real differentiators, and the app is comfortably the better of the two at 4.6/5 on iOS. On a system you monitor rather than a box you switch on, software quality is part of the product.
Worth knowing
Two things to carry into a $4,199 purchase. EcoFlow recalled the DELTA Max 2000 in October 2025 over overheating risk, a different model but the same company's quality control. And it offers no parts or service once the warranty expires, which is a long silent tail behind a 10-year promise.
Jackery
Ecosystem
Explorer portables and HomePower backup plus the SolarSaga panel line, sold through Costco, Home Depot, Best Buy and Amazon. The widest retail distribution in the category, which is why you can put hands on one before spending anything.
Support
US-based, and the weaker record of the two: slow and scripted responses, strict receipt requirements on warranty claims, refurbished replacements for units that failed while new. The workaround is identical to EcoFlow's. Buy from a retailer whose return policy outranks the manufacturer's warranty desk.
Community
Around 2,000 members on Reddit, the smallest of the major brands. If you like solving problems by searching a forum at 11pm, that well is much shallower than the EcoFlow side's.
App experience
Rated 2.3-3.3/5 iOS and Android — the weakest app experience of the major brands. Multiple confusing apps (Jackery app vs Jackery Home) and mandatory login even offline.
Unique strength
The Toyota position: recognized, proven, and on shelves everywhere. At 32 lbs for 1,536Wh it's also the lighter box here by a factor of more than five. Nobody buys a Jackery expecting to be surprised.
Worth knowing
The app is the weakest of the major brands at 2.3-3.3/5, with two separate apps and a mandatory login even offline. On a $949 box with a power button that's an irritation rather than a problem. Worth checking chemistry on any older Jackery you're also considering, since a few models still ship NMC with a shorter rated life. This one is rated at 4,000 cycles, more than the EcoFlow's 3,500.
Analyst note
Both brands' support is the weak link, and both get worked around the same way: buy from Costco or Amazon so the retailer's return window backstops the warranty desk. That single decision does more for you than choosing between them on brand reputation. Where they genuinely diverge is software, EcoFlow at 4.6/5 on iOS against Jackery's 2.3-3.3, and the asymmetry lands in the right place. The DELTA Pro Ultra is a system you monitor. The Explorer is a box with a button.
Growth path

EXPANDABLESupports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 6,144Wh.
Accepts up to 5,600W of solar. Enough for a serious multi-panel array.
Adequate ports for most setups, but heavy users may want a power strip.
Expansion batteries are EcoFlow-specific. You're investing in the EcoFlow ecosystem.

Analyst note
The Explorer 1500 v2 is sealed at 1,536Wh, which is fine if that covers you. The DELTA Pro Ultra starts at 6,144Wh and can grow beyond it with EcoFlow expansion batteries — real headroom the Explorer 1500 v2 doesn't have if your needs climb toward partial-home backup.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA Pro Ultra
Field evidence on the DELTA Pro Ultra is thinner than a $4,199 price tag deserves. Most of what exists is manufacturer material and reviewer write-ups rather than long-term owner reportsA1A2A3, and the LFP cycle rating of 3,500 to 80% is quoted from the same side of the fenceA2. The closest thing to real field data is the Home Depot review pool, where owners describe quick setup, strong solar input, useful app monitoring, and the 7,200W inverter running a 3-ton central ACA4.
One claim I'd file as unverified: a reviewer describes the unit as silent below 2,000WA3, which our own noise measurement doesn't corroborate. It also credits an 8,800W charge rate topping up two batteries in about two hoursA3, which is a multi-battery configuration rather than the single unit priced here. Fast, almost certainly. Silent, assume not until somebody with a meter says otherwise.
“6,144Wh per battery with 7,200W continuous output (10.8kW surge), expandable to 90kWh across a system for a household — over 30 days of essential backup.”

Jackery Explorer 1500 v2
The Explorer 1500 v2's coverage is unusually consistent, and nearly all of it is about the same thing: it's light. Roughly 32 lbs for 1.5kWh of LFP gets called class-leading across sourcesB1, the seven-output layout of three AC, dual USB-C and a DC car socket is singled out as genuinely useful rather than spec-sheet paddingB2, and a full recharge lands at about 64 minutesB3. Reviewers score it 8.7/10 as the cost-efficient route into real LFP capacityB4.
Two honest caveats. One source in the same ledger measured 37.4 lbs rather than 32, flagged as a measurement discrepancyB1. And every entry on both sides of this page is a reviewer or a retailer, not somebody two years in, so there's no long-term failure data here for either unitA1B4.
“The world's lightest 1.5kWh LFP power station at about 32 lbs — class-leading weight is one of its defining features.”

“Seven simultaneous outputs is genuinely useful: three AC outlets cover larger appliances, dual USB-C ports support fast charging for phones and laptops, and the DC car output handles 12V accessories without burning an AC outlet.”

Who Should Buy Which
Buy the DELTA Pro Ultra if you…
- →You have a well pump, central AC or a shop tool that needs more than 2,000W. The Explorer's absolute surge ceiling of 4,000W sits below the EcoFlow's 7,200W continuous rating, so this isn't a stretch for the Jackery, it's out of reach.
- →Your home office, workstation or medical gear can't tolerate a 20ms blink. The DELTA Pro Ultra's 0ms online handoff means the load never leaves battery power, so there's nothing to ride through.
- →You're living off solar rather than topping up at a campground. 5,600W of input replaces all 6,144Wh in about 1.1 hours at full rate; 400W needs about 3.8 hours to refill a battery a quarter the size.
- →Your daily draw is genuinely in four figures. The van-life day at 4,685Wh fits inside the EcoFlow with 537Wh of its 5,222Wh usable to spare, and doesn't fit inside the Jackery at all.
Buy the Explorer 1500 v2 if you…
- →You camp on weekends and run lights, a fan, phones and a small cooler. Under 1,306Wh a night, this is the entire answer for $949.
- →You're the one carrying it. 32 lbs is trunk-to-picnic-table with one hand, and 181.8 lbs is a lift you'll organize help for.
- →You want overnight CPAP backup. The modelled night is 320Wh, 25% of the Explorer's usable capacity, and buying the EcoFlow for that load means paying nearly six times as much for margin you'd never touch.
- →You rent, or you move often. Nothing here gets wired in, and a sealed 1,536Wh box with seven outputs travels without a plan.
If neither fits
If the load you're actually covering sits somewhere between 2,000 and 3,000Wh, a long outage with a fridge or a proper two-night camp, both of these miss it. The Explorer runs out (1,306Wh usable against your night) and the DELTA Pro Ultra answers it with 6,144Wh, 181.8 lbs and a $4,199 invoice. Shop the 2-3kWh middle of the market instead, where the price and the need line up. And if what you want is the whole house on backup through a transfer switch with no thinking involved, you don't want a portable at all. You want a wired standby generator or a permanently installed home battery.
The Bottom Line
Take the Explorer 1500 v2. It's $949, it weighs 32 lbs, it's rated for more cycles than the unit costing nearly six times as much, and it covers the CPAP night, the remote workday and the tailgate without straining. The DELTA Pro Ultra is the better machine on almost every line of the spec sheet, and none of that matters if the loads you actually run fit inside 1,306Wh.
One thing flips it: a load the Jackery physically cannot serve. Something above 2,000W, something that can't tolerate a 20ms transfer, or a day that needs more energy than the box holds. If that's you, don't buy the cheap one and hope, because the failure mode isn't slower or worse, it's off. Everyone else, take the Explorer and put the $3,250 into panels, the fridge, or the trip.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the DELTA Pro Ultra worth $3,250 more than the Explorer 1500 v2?
Only if you can name what the money buys. The extra $3,250 gets you 7,200W continuous instead of 2,000W, a 0ms handoff instead of 20ms, and 5,600W of solar input instead of 400W. It does not get you cheap energy: at $4,199 for 6,144Wh the EcoFlow works out to about $0.65 per watt-hour against the Jackery's $0.46 ($949 divided by 1,536Wh).
Can the Jackery Explorer 1500 v2 run my house during a blackout?
Not a house, and not a full eight-hour outage. The blackout scenario models 1,645Wh of essentials and the Explorer holds 1,306Wh usable (1,536Wh derated 15% for inverter losses), so it covers about 79% of it. Treat it as a fridge-and-devices unit for a short outage rather than whole-home backup, and note that it also hands over in up to 20ms rather than instantly.
Will the Explorer 1500 v2 run a CPAP all night?
Yes, several nights over. An eight-hour CPAP session models 320Wh, which is 25% of the Explorer's 1,306Wh usable capacity. Both units on this page clear it with room left, so capacity decides nothing here. Price and what you're willing to carry do.
Can I add more batteries to the Jackery Explorer 1500 v2?
No. It's fixed at 1,536Wh with no expansion path, so size it for the load you actually have rather than one you're planning for. The DELTA Pro Ultra does take EcoFlow expansion batteries, but it starts at 6,144Wh, four times the Jackery's total, so you'd be growing a unit that already dwarfs it.
Which one is better for van life or full-time off-grid?
The DELTA Pro Ultra, and it isn't close. The van-life day models 4,685Wh while the Explorer holds 1,306Wh usable, so it's short by a factor of more than three. Input rate matters as much as capacity when you're off-grid, and the EcoFlow accepts 5,600W of solar against the Explorer's 400W. Fair warning: even the DELTA Pro Ultra runs that day at 90% of its usable capacity.
