Spec deltas
The EcoFlow DELTA 3 1500 (1,536Wh) and Jackery Explorer 600 v2 (640Wh) sit in different weight classes. The real question: do your power needs justify the larger unit, or would you be overpaying for capacity that sits unused? The DELTA 3 1500 has a slight edge, but the margin is close enough that your use case should break the tie.
What the spec gap means in practice: the DELTA 3 1500's 1,800W inverter has the headroom for a window AC, a full-size fridge, and power tools. The Explorer 600 v2's 500W inverter can't run the heaviest of those — a window AC or a high-surge power tool needs more than it can hold, whatever its 1,000W surge ceiling does at the instant of startup. On stamina, the DELTA 3 1500 keeps a fridge alive for roughly 9 hours vs the Explorer 600 v2's 4 hours. The cost? Portability. At 36 lbs, the DELTA 3 1500 is heavy enough to make you think twice about moving it. The Explorer 600 v2 at 14.1 lbs is something one person can actually carry.
Pick the DELTA 3 1500 if your primary use is remote workday or tailgate party. Go with the Explorer 600 v2 if its specific strengths below line up better with your use. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.
Bench Notes
What each unit does well, where it falls short, and the trade-offs that matter.
EcoFlow DELTA 3 1500
The 1,800W inverter handles most daily devices like laptops, blenders, and TVs, but will struggle with heating elements that require over 1500W.
Strengths
- +Larger battery capacity
- +Higher AC output
- +Faster solar charging
Trade-offs
- –Significantly heavier (+21.9 lbs), making it harder to move.
- –Shorter-lived battery — rated for 3,000 charge cycles vs the Explorer 600 v2's 6,000, so it wears out sooner.
Jackery Explorer 600 v2
At 500W, this unit is strictly for personal electronics (phones, laptops) and small CPAP machines. Do not expect to run kitchen appliances. At only 14.1 lbs, it is exceptionally portable. You can easily carry it one-handed to a campsite or tailgating party.
Strengths
- +Lighter by 21.9 lb
- +Rated for 6,000 charge cycles — much longer battery lifespan
Trade-offs
- –Weaker inverter (-1,300W) limits appliance compatibility.
- –Sealed capacity — the DELTA 3 1500 can add batteries to grow past 640Wh; this one can't.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP is about 40W for eight hours, so both cover the night, though not twice: the Explorer 600 v2 gets through it with 224Wh to spare. What would separate them is fan noise, but DELTA 3 1500 doesn't publish a figure, so there's nothing to hold it to. Neither is sold new any more, so weight and fan noise is what's left to weigh, alongside whatever you can find used.

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 3 1500 rates 5.0/5 (99th percentile of 27 Everyday-class units), and Explorer 600 v2 rates 4.2/5 (53rd percentile of 20 Compact-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.
Explorer 600 v2: Fixed Capacity
The Explorer 600 v2 is sealed at 640Wh, and that is the ceiling. Normally the counterpoint would be that the DELTA 3 1500 can add expansion batteries, but that isn't a live option here: the DELTA 3 1500 is no longer sold, and EcoFlow points owners to the DELTA 3 Max. For a new purchase the expansion question doesn't arise between these two, so the Explorer 600 v2's fixed 640Wh is simply what you get.
UPS Switchover: ≤15ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The DELTA 3 1500 is rated ≤15ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. The Explorer 600 v2 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 Explorer 600 v2's figure is a maximum rather than a guarantee — it depends on registering the unit with Jackery, which is what extends the base term to the full period.
Battery Lifespan in Real Years
The Explorer 600 v2 is rated for 6,000 cycles vs 3,000. In real life: at daily use, that's 16.4 vs 8.2 years. At weekend use (twice a week), it's 58 vs 29 years. One caution reading years across different sizes: a cycle is 640Wh on the Explorer 600 v2 and 1,536Wh on the DELTA 3 1500, so count lifetime energy — roughly 3,840 kWh against 4,608 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.
DELTA 3 1500: Noise Level Not Disclosed
The Explorer 600 v2 publishes its noise level (30dB); the DELTA 3 1500 doesn't publish one. That isn't evidence the DELTA 3 1500 is louder — it means there's no figure to hold it to, and no way to compare the two on this without hearing them. If you're buying for a bedroom, a CPAP, or an apartment, treat the Explorer 600 v2's 30dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the DELTA 3 1500 before deciding.

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 3 1500 delivers about 4,608 kWh and the Explorer 600 v2 about 3,840 kWh. One caution on the lifespan row: the Explorer 600 v2 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the DELTA 3 1500 still delivers more over its shorter horizon. Years measure wear, not usefulness.
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
EcoFlow and Jackery are close competitors. Both have established support channels and growing ecosystems. Compare their specific warranty terms and community size for your peace of mind.
Growth path
DELTA 3 1500
EXPANDABLESupports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 1,536Wh.
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 600 v2
FIXED CAPACITYFixed at 640Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 200W of solar. Limited to a single portable panel.
Limited ports. You'll likely need a power strip or splitter.
Realistic full solar rechargeat 70% of rated panel output — see methodology
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 3 1500 takes expansion batteries and the Explorer 600 v2 is fixed at 640Wh. As a purchase decision, expandability isn't the question here.
The Bottom Line
The full picture comes down to this. The DELTA 3 1500 edges ahead on our overall analysis, but the margin is narrow enough that your specific use case should drive the decision. Review the scenario verdicts above — if the Explorer 600 v2 wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the DELTA 3 1500 nor the Explorer 600 v2 feels like the right fit, your power needs probably sit outside what these two target. Use our comparison tool above to explore alternatives that better match your specific wattage and runtime requirements. Prices on portable power stations fluctuate frequently. Both EcoFlow and Jackery discount regularly, so check the current price before committing. Prime Day and Black Friday pricing typically drops 20-30%.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
How does the 896Wh capacity difference actually affect daily use?
The DELTA 3 1500's 1,536Wh battery keeps a mini-fridge running for roughly 9 hours vs the Explorer 600 v2's 4 hours. What specs don't mention: runtime drops 20-30% in cold weather (below 32°F/0°C) as battery chemistry slows down. The DELTA 3 1500's extra capacity provides a critical cold-weather buffer. For occasional phone and laptop charging, both are overkill. This gap only matters for sustained, multi-appliance use.
Can I actually carry the DELTA 3 1500, or is the Explorer 600 v2 the only portable option?
The Explorer 600 v2 at 14.1 lbs is genuinely grab-and-go. Toss it in a backpack, carry it one-handed to a picnic, take it on a boat. The DELTA 3 1500 at 36 lbs is a different story. It's like carrying a large suitcase full of books. If you're setting up and breaking down camp frequently, this weight difference will exhaust you by day two.
How fast can each unit recharge from solar panels in real conditions?
On paper, the DELTA 3 1500 accepts 500W vs the Explorer 600 v2's 200W of solar input. What the spec sheet won't tell you: solar panels typically deliver only 60-80% of their rated output due to panel angle, cloud cover, and temperature. In realistic conditions, expect full recharge in about 4.4 hours for the DELTA 3 1500 and 4.6 hours for the Explorer 600 v2. That gap widens on cloudy days, when the DELTA 3 1500's higher input ceiling captures more of whatever sunlight is available. One more thing: summer gives you ~7 productive solar hours per day. Winter drops to ~4. If solar is your primary recharge method, the DELTA 3 1500's advantage is substantial.
"6,000 vs 3,000 cycles" — what does that actually mean for me?
In real years: the Explorer 600 v2 (6,000 cycles) lasts 16.4 years at daily use, 58 years at weekend use (twice a week), or 250 years at twice-monthly camping trips. The DELTA 3 1500 (3,000 cycles): 8.2 years daily, 29 years weekends, or 125 years twice-monthly. What most people miss: hitting the cycle limit doesn't kill your battery. Capacity drops to about 80%. Your 640Wh unit becomes a ~512Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
What if I need more capacity than the Explorer 600 v2's 640Wh later?
The Explorer 600 v2 is sealed at 640Wh, so if you expect your needs to climb, the DELTA 3 1500 is the more future-proof pick: it starts at 1,536Wh and adds EcoFlow-compatible batteries without replacing the base unit. That said, "not expandable" isn't a flaw on its own — if 640Wh comfortably covers your loads, the Explorer 600 v2 is a complete unit, not a downgrade.
Is EcoFlow or Jackery more reliable for long-term ownership?
Both brands have strengths and trade-offs. EcoFlow: Mixed. 2-5 years depending on model. Some users report smooth claims; others report runarounds. Register your product to extend coverage. Jackery: 2-5 years depending on model (premium models like 5000 Plus get 5 years, budget models get 2 years). Registration required for extension. Claims process can be frustrating. One piece of advice from the power station community: regardless of brand, buy from Costco or Amazon. Their return policies provide a safety net that manufacturer warranties alone can't match, especially for a product you'll rely on in emergencies. Both brands use LFP (lithium iron phosphate) batteries in their current lineup, the most proven chemistry for longevity and safety.
Bottom line: should I buy the DELTA 3 1500 or the Explorer 600 v2?
Neither, if you're buying new: both are no longer sold. The comparison on this page still helps if you own one.
