EcoFlow DELTA 2 vs Jackery Explorer 2000 Plus
Neither of these is for sale any more, so the axis isn't which one wins. It's whether your loads ever needed more than the DELTA 2's 870Wh of usable energy, because that one answer sends you to one of two live successors.

Spec deltas
Both of these units are discontinued, and they left in different ways. EcoFlow no longer sells the DELTA 2 at all: its store page forwards to the DELTA 3, which is the like-for-like replacement. Jackery's Explorer 2000 Plus is a softer exit. The listing is still there, but it now carries only kits, the add-on battery and a refurbished unit, so the standalone box is what's gone. Its successor in the line is the HomePower 2000 Plus v2.
That kills the recommendation and leaves the comparison, which is the part worth having. Two kinds of reader land here. One owns a DELTA 2 or an Explorer 2000 Plus and wants to know what they're holding. The other typed a model name into a search box and needs telling that the line moved on, plus which way it went. The specs answer both, and they're still accurate.
On paper the Explorer 2000 Plus was the bigger machine everywhere electricity is measured: 2,043Wh against 1,024Wh, 3,000W continuous against 1,800W, a 6,000W surge ceiling against 2,700W, 1,400W of solar input against 500W, 4,000 rated cycles against 3,000. The DELTA 2's counter-arguments were 27 lbs against 61.5, six AC outlets against five, and four USB-A ports against two. That shape holds all the way down the page.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
solar input
Neither unit covers a day of van life, which tells you what these packs actually are when you live off one: a buffer, with the panels doing the real supplying. A 500W ceiling makes solar a top-up between uses. A 1,400W ceiling makes it a supply line you can run under load. That's the difference between a unit that's full when you get home and one that's full while you're using it.
DELTA 2: 1,024Wh capacity behind a 500W solar input ceilingExplorer 2000 Plus: 2,043Wh capacity behind a 1,400W ceilingThe van life profile asks 4,685Wh a day; the Explorer falls 2,949Wh short and the DELTA 2 3,815Wh short
Why it mattersIf you own a DELTA 2 and keep running dry, buying more panels stops helping at 500W of input. The ceiling is the thing you've outgrown, not the array.
continuous output
So the weight question resolves on what you plug in rather than on how much energy you need. Work the arithmetic backwards from the DELTA 2's 2,700W ceiling at the 3x worst case and it covers a roughly 900W-rated motor, which is most household fridges. Under that line its ceiling is as useful as the Explorer's 6,000W and you carry 34.5 fewer pounds to get it. Above it, only one of these two is comfortable, and 61.5 lbs is the entry fee.
DELTA 2: 27 lbs, 1,800W continuous, 2,700W surgeExplorer 2000 Plus: 61.5 lbs, 3,000W continuous, 6,000W surgeThe largest startup draw any scenario on this page asks for is 400W, at the tailgate, and both units start it
Why it mattersIf the heaviest thing on your list is a laptop, a fan and a coffee maker, the lighter unit was never the compromise. If it's a chest freezer or a table saw, the lift was the whole point.
rated cycles
Past its rated cycles a pack doesn't die, it settles at roughly 80% of original capacity. On the Explorer that's about 1,634Wh, which is still more than a brand-new DELTA 2's 1,024Wh nameplate. So a heavily used Explorer can be the larger unit of the two even after the DELTA 2 it's compared against has never been cycled, and on the Jackery you can read the count out of the app instead of guessingB4.
Explorer 2000 Plus rated 4,000 cycles, DELTA 2 rated 3,000, both as minimumsRated lifetime energy: 8,171 kWh against 3,072 kWh, because a cycle moves 2,043Wh on one and 1,024Wh on the otherThe Jackery app reports cycle counts and efficiency graphsB4
Why it mattersAnyone taking on either unit secondhand should ask for the cycle count before the price. On the Explorer that's a number you can verify rather than a claim you have to trust.
Which means noise was never the thing separating these two at a bedside. Both are quiet at 40W and neither published rating tells you so. What actually separates them there is nights of cover and whether you have to move the box: 870Wh usable is two nights, 1,736Wh is five, and 27 lbs walks to the bedroom while 61.5 lbs does not.
A CPAP is about 40W, or 320Wh across an eight-hour nightThe DELTA 2's fans trigger above 120 watts and run continuously at roughly 48-55 dB at its 1,500-1,800W maximum loadA1Reviewers describe the Explorer 2000 Plus as relatively quiet even under a 3,000W loadB1
Why it mattersCPAP buyers should stop reading dB figures on either unit and choose on consecutive nights of cover, which is the one axis where the size difference is real.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: Usable energy after the flat 15% conversion allowance, 870Wh against 1,736Wh, is what every load profile on this page gets measured against.
continuous output
The flat 15% conversion allowance is where the DELTA 2's nameplate stops flattering it. 1,024Wh becomes 870Wh usable, and 870Wh is exactly the figure that loses the remote workday by 40Wh. Its nameplate would have cleared that 910Wh load with room. The derate is what tips it under, which is a useful thing to know about your own unit: you have about a workday, not a day.
The Explorer's 1,736Wh is a different category of answer rather than a better score on the same one. It finishes that same workday with 826Wh still in the pack, which is another laptop day sitting in reserve. Neither figure is a reason to buy anything now. Both are reasons to know which of these two is in your closet before you plan a weekend around it.
Your Life, Your Pick
Selected because: Six load profiles: the Explorer 2000 Plus covers four of them outright, the DELTA 2 covers two, and neither covers van life's 4,685Wh.
The honest surprise is the weekend, where both units fail. The camping profile wants 2,100Wh and the Explorer's entire nameplate is 2,043Wh, so even the big one lands 364Wh short and covers 83% of the list. The DELTA 2 covers 41%. Read those as partial cover rather than failure: the fridge and the lights are inside both numbers, the full list isn't inside either.
The tailgate row is the one place the DELTA 2's case shows up in the results. Both units handle game day easily at 670Wh, so the number you feel isn't capacity, it's the walk from the trunk. And van life is where the page politely stops being about these two: 4,685Wh a day leaves the larger unit 2,949Wh short, and the answer to that is a bigger station or a stacked system, not a choice between a pair of discontinued boxes.
Growth Path
Selected because: Both units take expansion batteries, and the Explorer 2000 Plus's add-on battery is still on a listing that no longer sells the unit itself.
solar input
Expansion is the Explorer's headline and it is genuinely large. Each unit's battery scales toward 12kWh, and pairing two of them reaches 6,000W of output and up to 24kWh totalB2. The DELTA 2 expands too, but from a 1,024Wh base and behind a 500W solar ceiling, so the bank grows faster than anything can refill it.
The retirement changes what that's worth in opposite directions. Jackery's listing still carries the add-on battery even though it no longer sells the unit, so if you own one, your capacity path is intact. Go looking for the same upgrade on the DELTA 2 side and you land on a page that forwards to the DELTA 3, which is EcoFlow answering a different question than the one they asked. Check the accessory listing before you plan an upgrade around either one.
What the Specs Don't Tell You
Selected because: Five cards fire on this pair, and only the weight card lands in the DELTA 2's favour.
rated cycles
The surge card is the one that changes what you're allowed to plug in. 6,000W against 2,700W, and a 2x surge-to-continuous ratio against 1.5x, is the difference between assuming a motor will start and checking first. It cuts both ways, though: what decides a startup is the absolute ceiling, not the ratio, so if the DELTA 2 is the one you have, look up the inrush figure on your heaviest appliance rather than assume 2,700W trips.
The noise card looks like a clean win for the Explorer and isn't. One maker publishes a best-case floor and another a figure under load, so the two ratings on these spec rows are not the same kind of number and the distance between them is not a gap you can hear. Treat the pair as a prompt to find hands-on reports, not as a measurement.
Brand Trust
Selected because: With neither unit for sale, the live decision is which brand's line you step into next.
This column is the only part of the page still picking something, because whichever unit you came for, what you can actually buy is a line. EcoFlow gives you the deeper bench and a far bigger community, roughly 31,000 on Reddit against about 2,000 for Jackery, which is what you're leaning on at 11 p.m. when something won't charge. Jackery gives you the shelf instead: Costco, Home Depot, Best Buy, Amazon, so a Jackery is usually the one you can put your hands on before you pay.
The apps split hard, 4.6/5 on iOS for EcoFlow against 2.3 to 3.3 for Jackery, and Jackery runs more than one of them. The irony for this pair is that the weaker-rated app is the one that hands an owner the number that matters on a used unit, since it reports cycle counts and efficiency graphsB4. Ratings measure polish. This one is about whether you can audit what you own.

Neither unit
Neither unit covers this scenario's 2,100Wh: the DELTA 2 comes up 1,230Wh short (about 41% covered), the Explorer 2000 Plus 364Wh (83%). Treat this as partial cover — enough for the essentials in it, not the whole list.

Explorer 2000 Plus
The Explorer finishes this one and the DELTA 2 gets about 53% of the way, but read the winning margin before you relax. 91Wh left in a 1,736Wh pack is about 5%, which is a pass rather than a cushion, and one load you didn't plan for turns it into a near miss. The DELTA 2 isn't close: 870Wh usable against 1,645Wh needed leaves it 775Wh short, which is not a near miss at any point in the night.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
One night was never the question here. A CPAP is about 40W, or 320Wh across eight hours, and both of these swallow that whole several times over. Count nights instead, which is why the Explorer takes this row: 870Wh usable is two nights on the DELTA 2 against five on the Explorer. On the thing you actually care about at 3 a.m., the published noise ratings can't help you, because each maker measures its own way and neither figure describes a 40W draw. Find a hands-on report before either box sleeps beside your head.

Explorer 2000 Plus
The DELTA 2 comes up just short — it needs 910Wh and has 870Wh usable, a 40Wh gap (its nameplate 1,024Wh actually clears this — the flat 15% conversion allowance is what tips it under). Trim that much — one small appliance's worth across the day — and it finishes. The Explorer 2000 Plus covers it outright with 826Wh to spare.

Both handle game day; the Explorer 2000 Plus keeps more in reserve (39% used vs 77%). Tailgating is a light load, though, so the number you'll feel is weight: 27 lbs for the DELTA 2 against 61.5 lbs for the Explorer 2000 Plus, from the trunk to the setup spot.

Conclusion
September 19, 2026
Verdict: the Explorer 2000 Plus, on Power Score margin
A tie, because nothing on this page can be bought. The Explorer 2000 Plus was the better machine and it wasn't close: 2,043Wh against 1,024Wh, a 3,000W inverter against 1,800W, 6,000W of surge ceiling against 2,700W, 1,400W of solar input against 500W. But a recommendation needs something in stock, and here there are two live answers instead of one. EcoFlow's DELTA 2 page forwards to the DELTA 3, the like-for-like replacement. Jackery's Explorer 2000 Plus listing now carries only kits, the add-on battery and a refurbished unit, and the line's successor is the HomePower 2000 Plus v2. Sort yourself by size: if 1,024Wh and a 27 lb one-hand carry covered your list, follow EcoFlow's replacement. If you needed the 2 kWh class and an inverter that starts motors, follow Jackery's. And if you already own one of these, nothing here says sell it. The specs are still true, and on the Explorer a 4,000-cycle rating leaves a lot of road.

Power Score
Computed from 14 published spec dimensions, weighted per use-case bench. Higher is better; a unit must meet a bench's minimum threshold to be rated.
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 2 rates 4.1/5 (50th percentile of 27 Everyday-class units), and Explorer 2000 Plus rates 4.6/5 (74th percentile of 28 Large-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Explorer 2000 Plus: 61.5 lbs Is a Planned Lift
Sixty-one and a half pounds is two hands and bent knees, and a second person if stairs are involved. The DELTA 2's 27 lbs is the one axis where it beats the Explorer outright, and it beats it by more than double. This isn't the Explorer being badly built: 2,043Wh across 61.5 lbs works out at about 33Wh per pound against the DELTA 2's 38, so the extra mass is mostly more cells plus a bigger inverter. It still has to travel from the car to wherever you need it. If you're arranging to collect one secondhand, the weight is the logistics rather than a footnote.
DELTA 2: 50dB Published
50dB is about as loud as moderate rainfall. The Explorer 2000 Plus is rated 30dB — lower, but published by a different maker measuring its own way, so the two figures are not a like-for-like gap. For most people, fan noise around 45dB and up is where sleep starts to suffer.
Surge Power: Inverter Quality Indicator
The Explorer 2000 Plus has a 2× surge-to-continuous ratio vs the DELTA 2's 1.5×, and the higher absolute ceiling with it — 6,000W against 2,700W. At 2× it clears the 2× rule of thumb for absorbing motor startups — fridges, AC compressors and power tools briefly draw 2-3× their rated wattage. What decides whether a given motor starts is the ceiling, not the ratio: the DELTA 2 still surges to 2,700W, so check the startup draw of the heaviest thing you plan to run against that figure rather than assuming it trips.
Warranty: Same Term, and the Clock Already Started
Both units carry five years, so coverage was never the tiebreaker. On a discontinued unit the term matters less than when it began. Jackery's five is a maximum rather than a guarantee: three years, plus two more once you register the unit, so an unregistered Explorer sits on the shorter term. EcoFlow's five is stated plainly with no condition attached. The part to plan around is that EcoFlow does not offer parts or service out of warranty, which on a model whose store page now points at its replacement makes your remaining term the whole story. Keep the receipt, and register whatever is still registerable. With both models off the shelves, a receipt is the difference between a claim and a conversation.
Battery Lifespan in Real Years
The Explorer 2000 Plus is rated for 4,000 cycles vs 3,000. In real life: at daily use, that's 11 vs 8.2 years. At weekend use (twice a week), it's 38 vs 29 years. One caution reading years across different sizes: a cycle is 2,043Wh on the Explorer 2000 Plus and 1,024Wh on the DELTA 2, so count lifetime energy — roughly 8,171 kWh against 3,072 kWh over the rated life. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.

Analyst note
Neither is sold new any more, so there is no price left to work a cost per kWh from, and what either costs you now depends on the used market. The hardware comparison still holds: over its rated life the DELTA 2 delivers about 3,072 kWh and the Explorer 2000 Plus about 8,171 kWh.
Brand trust
EcoFlow
Ecosystem
Largest in portable power — 12-15 models across DELTA Pro, DELTA 3, and RIVER 3 series, plus solar panels and smart home panels
Support
US-based phone/email/chat support (1-800-368-8604). Experiences are polarized — many report hassle-free prepaid-label replacements, but others report long waits and refurbished units sent for new claims. Pro tip: buying from Costco or Amazon gives you a stronger return safety net.
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
Fastest-charging technology (X-Stream), deepest product ecosystem, and most active innovation cadence. At the top of the range sit two whole-home paths: the TITAN line, one 5 kWh unit that grows to 30 kWh, and the DELTA Pro Ultra platform, which stacks batteries and inverters further — flagship paths, not line-wide features.
Worth knowing
Tested subscription paywalls for advanced app features in early 2025 before community backlash paused the plan. No parts or service offered out of warranty.
Jackery
Ecosystem
12-15+ models across Explorer (portable) and HomePower (home backup) series, plus SolarSaga panel ecosystem and innovative form factors
Support
US-based support but widely criticized. Reddit reports describe slow/dismissive responses, scripted AI agents, strict receipt requirements for warranty claims, and refurbished replacements for clearly defective units. Strongly recommended: buy from Costco or Amazon for return protection.
Community
Smallest community of the major brands — Reddit r/Jackery has ~2,000 members. YouTube presence is solid due to brand recognition.
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
Highest brand recognition and widest retail distribution (Costco, Home Depot, Best Buy, Amazon). The "Toyota" of power stations — dependable, proven, wide availability. Innovative form factors like the Solar Gazebo and Solar Mars Bot.
Worth knowing
A couple of older models still ship NMC chemistry with a shorter rated lifespan, so check the cycle rating on the specific unit — though most of the current line has moved to LFP. Generally perceived as overpriced for the specs offered compared to newer competitors. App experience is significantly behind rivals.
Analyst note
With neither unit for sale, this column stops being background and becomes the actual decision: whichever box you came here for, what you can buy is a line. EcoFlow offers the deeper bench, 12 to 15 models across three current series plus panels and home panels, and by far the bigger owner community at roughly 31,000 on Reddit against about 2,000 for Jackery. That community is what you lean on when something misbehaves at 11 p.m. Jackery offers the shelf instead: Costco, Home Depot, Best Buy and Amazon, which is why a Jackery is usually the one you can see and lift before you pay for it. The apps are the clearest split, 4.6/5 on iOS for EcoFlow against 2.3 to 3.3 for Jackery, and Jackery runs more than one app with a login required even offline. One piece of advice covers both lines: buy through a retailer with its own returns desk. It costs nothing and it sits in front of the warranty as a second backstop.
Growth path
DELTA 2
EXPANDABLESupports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 1,024Wh.
Accepts up to 500W of solar. Suitable for a 1-2 panel setup.
Generous port selection supports complex multi-device setups.
Expansion batteries are EcoFlow-specific. You're investing in the EcoFlow ecosystem.
Explorer 2000 Plus
EXPANDABLESupports Jackery expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 2,043Wh.
Accepts up to 1,400W 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 Jackery-specific. You're investing in the Jackery ecosystem.

Analyst note
Neither of these is sold new any more, so there is no growth path to buy into on either side. If you already own one: the DELTA 2 takes expansion batteries and the Explorer 2000 Plus takes expansion batteries. As a purchase decision, expandability isn't the question here.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 2
Eighteen months of testing across power outages, camping trips and daily home-office use came back positive on reliability, fast charging and expandabilityA3, and our own coverage note calls the field data solid and multi-month with noise as the one consistent gripeA0. That gripe is specific rather than vague: the fans trigger above 120 watts, and at the unit's 1,500-1,800W maximum they run continuously at roughly 48-55 dBA1. Charging at 1,200W has been compared to a gaming laptop, though the app can slow the charge rate to quiet it downA2.
One caveat on how you read older reviews of this unit. EcoFlow said it intended to address fan behaviour in a firmware update, as it has on other models after releaseA4, so a launch-era noise complaint may not describe the unit sitting in your garage. The 120W trigger point is the part worth remembering, because it means light loads and heavy loads are two different machines acoustically.
“When charging at 1200W the fans sound like a gaming laptop, though you can lower the charging speed in the app to silence it.”

Jackery Explorer 2000 Plus
Reviewers describe it as dependable, easy to use and relatively quiet even under a 3,000W load, running everything from CPAP machines to electric grillsB1. Two MPPT inputs and an IP65-rated build on key ports draw repeated praiseB5, and the app earns credit for owner-grade detail like cycle counts and efficiency graphs while still being described as unpolishedB4. The weight is where everyone lands: at 61-62 lbs the included wheels and handle help on smooth ground, but stairs are a two-person jobB3.
One flag from our own research rather than from the field. Solar input is cited variously between about 1,200W and 1,400W across sourcesB0B5, so treat the ceiling as approximate rather than a figure to size a panel array against to the watt. The expansion headroom is the other consistent theme: each unit's battery scales toward 12kWh and a pair reaches up to 24kWhB2, which is why this unit kept turning up in RV and home-backup builds rather than camping ones.
“Reviewers describe it as dependable, easy to use, and relatively quiet even under a 3000W load, with universal compatibility for powering everything from CPAP machines to electric grills.”

“Fans trigger at anything above 120 watts; at maximum load (1,500–1,800W) they run continuously at ~48–55 dB. Powering medical equipment above 120W in a bedroom means listening to the fans or running an extension cable out of the room.”

“When charging at 1200W the fans sound like a gaming laptop, though you can lower the charging speed in the app to silence it.”

Claims are weighted by how specific they are, whether the commenter owns the unit, and how many readers agreed. Comments that mention a product under a rival's review count for more, because the commenter had no reason to be there. This is what buyers report, not our test results — for measurements we ran ourselves, see the methodology.
Who Should Buy Which
Buy the DELTA 2 if you…
- →You carry the unit more often than you charge it, out of a trunk and over a tailgate with one hand at 27 lbs. That shape is what the DELTA 3 replaces, so start there. The DELTA 2 itself is only an option if you turn up retailer or used stock.
- →Your whole list is a CPAP, a laptop and phones. 320Wh a night against 870Wh usable is two nights of cover, and at 40W you stay under the 120W point where the fans come onA1. If you already own one, you're well served and there's nothing to fix.
- →You want expansion from a small base and mains charging is your normal refill. The DELTA 2 does that, and if you're shopping rather than already holding one, EcoFlow's replacement is the DELTA 3.
Buy the Explorer 2000 Plus if you…
- →Your heaviest load starts a motor: a fridge, a well pump, a table saw. 6,000W of surge behind a 3,000W continuous rating is the headroom that starts those things, and it's the only reason to accept 61.5 lbs. The live equivalent is Jackery's HomePower 2000 Plus v2.
- →You want one box to see out an eight-hour outage. This is the unit that finishes it, by 91Wh of its 1,736Wh usable, which is a pass rather than a cushion. If you own one, add panels before you add anything else, because 1,400W of input is what makes day two survivable.
- →You already own one and want more capacity. The add-on battery is still on the listing even though the unit isn't, so your upgrade path is the one thing about this retirement that went your way.
If neither fits
Anyone trying to run a van or a whole house off a single box should skip both. The daily van profile wants 4,685Wh and the larger of these two comes up 2,949Wh short, which is a bigger station or a stacked system rather than a choice between these. And if you only need to keep a phone, a fan and a router alive through a short outage, both of these are two classes more unit than the job needs. Buy something small, new, and with a warranty clock that starts when you do.
The Bottom Line
Both of these are records now rather than options. The Explorer 2000 Plus was the stronger machine and the specs don't argue about it: twice the usable energy, a surge ceiling that starts motors the DELTA 2 has to be checked against first, and a solar input that can refill the whole pack in a morning. The DELTA 2's case was 27 lbs, and that was a real case, just a narrower one.
So take the answer instead of the winner. If 870Wh of usable energy covered your list and you'd rather lift the thing with one hand, EcoFlow's DELTA 3 is where that shape went. If you needed the 2 kWh class and an inverter that doesn't flinch at a compressor, Jackery's HomePower 2000 Plus v2 is where that shape went. And if one of these is already sitting in your garage, go read its cycle count. That's the number that decides what you've got left, and it's the only one on this page you can still act on.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow DELTA 2 discontinued?
Yes. EcoFlow's DELTA 2 page now forwards to the DELTA 3, which is the like-for-like replacement, and that's why this page shows no price for it. The unit itself is not defective or recalled, it's simply out of the maker's range. You may still find retailer or used stock, and the specs on this page remain accurate for it.
Can you still buy the Jackery Explorer 2000 Plus?
Not as a standalone unit. Jackery's listing now carries only kits, the add-on battery and a refurbished unit, so the box on its own is what's gone. The successor in the line is the HomePower 2000 Plus v2. If you already own one, the add-on battery still being listed means your expansion path is intact.
I own a DELTA 2 and keep running out. Do I need a bigger unit?
Check the size of the shortfall first. Your usable figure is about 870Wh once the flat 15% conversion allowance comes off 1,024Wh, and a standard eight-hour blackout profile wants 1,645Wh, which leaves you 775Wh short. That's three-quarters of the unit's entire nameplate missing, and no amount of solar closes it because your input ceiling is 500W. If that's the wall you keep hitting, you need the 2 kWh class the Explorer 2000 Plus occupied, not another panel.
Which was actually the better power station?
The Explorer 2000 Plus, on everything that moves electricity: 2,043Wh against 1,024Wh, a 3,000W inverter against 1,800W, a 6,000W surge ceiling against 2,700W, 1,400W of solar input against 500W, and 4,000 rated cycles against 3,000. The DELTA 2's answers were 27 lbs against 61.5, six AC outlets against five, and four USB-A ports against two. Since neither is for sale, treat that as a way of sorting yourself into the right live line rather than as a verdict.
How do I check a used Explorer 2000 Plus before taking one on?
Ask for the cycle count before anything else. The Jackery app reports cycle counts and efficiency graphs, which makes this one of the few used power stations you can genuinely audit. The rating is 4,000 cycles, and past that a pack settles at roughly 80% of original capacity rather than failing, which on 2,043Wh is about 1,634Wh, still more than a brand-new DELTA 2's 1,024Wh. Then plan the collection: it's 61.5 lbs, and the wheels only help on smooth ground.
