Spec deltas
The EcoFlow DELTA 2 (1,024Wh) 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? We'd buy the DELTA 2.
The DELTA 2 holds 384Wh more than the Explorer 600 v2 — about 6 hours on a fridge against 4 — a real but modest edge that shows up mainly on longer outages. For camping, tailgating, or keeping devices charged, both have the headroom, so price, weight, and longevity lead the decision instead.
Pick the DELTA 2 if your primary use is tailgate party. Go with the Explorer 600 v2 if you primarily need it for cpap overnight. Most buyers stop at the sticker price and miss this: over a full lifespan the Explorer 600 v2 works out to about $0.13/kWh against the DELTA 2's $0.16, a gap that compounds in the Explorer 600 v2's favor the more you cycle it. 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 2
The 1,800W inverter handles most daily devices like laptops, blenders, and TVs, but will struggle with heating elements that require over 1500W. A standout feature is the value proposition: at roughly $0.49 per watt-hour, it's one of the most cost-effective options on the market.
Strengths
- +Larger battery capacity
- +Higher AC output
- +Faster solar charging
Trade-offs
- –Significantly heavier (+12.9 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 12.9 lb
- +Rated for 6,000 charge cycles — much longer battery lifespan
Trade-offs
- –Weaker inverter (-1,300W) limits appliance compatibility.
- –Sealed capacity — the DELTA 2 can add batteries to grow past 640Wh; this one can't.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Explorer 600 v2
A CPAP is about 40W for eight hours, so both of these cover the night several times over — capacity isn't the question here, and the percentages are a formality. What matters is the box next to your pillow, and the only published difference is a rating: the Explorer 600 v2 is rated 30dB against the DELTA 2's 50dB. Each is the maker's own published rating, and the makers do not measure the same way, some quoting a best case and some a figure under load, so neither number describes a 40W draw and the two are not really comparable. Treat them as a reason to look for hands-on reports before either one goes next to a bed, not as a difference you can count on hearing.

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 (46th percentile of 27 Everyday-class units), and Explorer 600 v2 rates 4.2/5 (53rd percentile of 20 Compact-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
DELTA 2: 50dB Published
50dB is about as loud as moderate rainfall. The Explorer 600 v2 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.
Explorer 600 v2: Fixed Capacity
The Explorer 600 v2 is sealed at 640Wh — fine if that covers you, but it's the ceiling. By contrast the DELTA 2 can add expansion batteries, though the first thing it has over the Explorer 600 v2 is its own 1,024Wh base — expansion is the step after that, for the buyer who would outgrow 1,024Wh as well.
Surge Power: Ratio and Ceiling Disagree
The Explorer 600 v2 holds the higher surge-to-continuous ratio (2× vs 1.5×), but the DELTA 2 holds the higher absolute surge ceiling — 2,700W against 1,000W. These measure different things. The ratio says how much headroom an inverter keeps above its own rating; the ceiling says how big a startup spike it can actually swallow. A motor draws a number of watts at switch-on, not a multiple of someone else's rating, so on raw starting ability the DELTA 2 is the stronger unit here — while the Explorer 600 v2 is the one running further below its own limit at steady state.
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 1,024Wh on the DELTA 2, so count lifetime energy — roughly 3,840 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.
Full record above — the Test Desk pick is the DELTA 2.

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 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 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
The Explorer 600 v2 is sealed at 640Wh, which is fine if that covers you. The DELTA 2 starts at 1,024Wh and can grow beyond it with EcoFlow expansion batteries — though at this size expansion means longer runtimes on the same loads, not a path to home backup. More hours, not more house.
The Bottom Line
The full picture comes down to this. The DELTA 2 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 2 nor the Explorer 600 v2 feels like the right fit, your power needs probably sit outside what these two target. If you're planning whole-home backup or running power-hungry appliances (electric heaters, window AC), you'll want a larger system in the 3,000–5,000Wh range with expansion battery support. 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.
Can I actually carry the DELTA 2, 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 2 at 27 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 2 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 2.9 hours for the DELTA 2 and 4.6 hours for the Explorer 600 v2. That gap widens on cloudy days, when the DELTA 2'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 2'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 2 (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 2 is the more future-proof pick: it starts at 1,024Wh 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 (DELTA Pro Ultra line gets 10 years). 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 2 or the Explorer 600 v2?
We'd pay the premium for the DELTA 2. Yes, it costs more. The capability jump is real: you're stepping into a tier that handles appliances the base model can't start. The Explorer 600 v2 is still solid if budget is the priority, but the DELTA 2 will leave you less likely to wish you'd "gone bigger" six months from now. That regret costs more than the price difference.
