Spec deltas
The EcoFlow DELTA Pro (3,600Wh) and Jackery Explorer 1500 v2 (1,536Wh) 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 Pro 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 Pro's 3,600W inverter has the headroom for a window AC, a full-size fridge, and power tools. The Explorer 1500 v2's 2,000W inverter still runs most single appliances; the DELTA Pro's real edge is surge headroom for the biggest motor starts and stacking several heavy loads at once. On stamina, the DELTA Pro keeps a fridge alive for roughly 20 hours vs the Explorer 1500 v2's 9 hours. The cost? Portability. At 99 lbs, the DELTA Pro is heavy enough to make you think twice about moving it. The Explorer 1500 v2 at 32 lbs is something one person can actually carry.
Pick the DELTA Pro if your primary use is weekend camping or 8-hour blackout. Go with the Explorer 1500 v2 if its specific strengths below line up better with your use. Cost to own is level here — about $0.15/kWh each over a full lifespan — so it won't be the tiebreaker. 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 Pro
With a massive 3,600W output (and 7,200W surge), the DELTA Pro can run high-wattage appliances like space heaters, hair dryers, and electric grills without tripping. Weighing in at 99 lbs, this is not a unit you want to carry far. It's best suited as a stationary backup or RV companion. A standout feature is the value proposition: at roughly $0.53 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
- –Substantially more expensive (+$950) than the Explorer 1500 v2.
- –Significantly heavier (+67 lbs), making it harder to move.
- –Very heavy unit that may be difficult for one person to lift.
- –Can receive complaints about fan noise under heavy load.
Jackery Explorer 1500 v2
The 2,000W inverter handles most daily devices like laptops, blenders, and TVs, but will struggle with heating elements that require over 1500W.
Strengths
- +Costs $950 less
- +Lighter by 67 lb
Trade-offs
- –Weaker inverter (-1,600W) limits appliance compatibility.
- –Sealed capacity — the DELTA Pro can add batteries to grow past 1,536Wh; 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 of these cover the night several times over — capacity isn't the question here. The only published difference is fan noise, and it can't settle this: the Explorer 1500 v2 is rated 30dB and the DELTA Pro 60dB, but they are two makers' figures, each measured its own way. Neither settles which box is quieter at a bedside. Buy whichever is cheaper or easier to carry.

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 rates 3.7/5 (26th percentile of 20 Home Backup-class units), and Explorer 1500 v2 rates 3.8/5 (31st 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.
DELTA Pro: 99 lbs Is a Commitment
At 99 lbs, this is manageable but not fun to move. That's heavier than a large checked suitcase. How much it costs you depends on whether it rolls — wheels and a telescoping handle change the job completely at this weight, and our spec record doesn't track them, so look at the product photos before you plan on carrying it from the car.
DELTA Pro: 60dB Published
60dB is about as loud as a normal conversation. The Explorer 1500 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 1500 v2: Fixed Capacity
The Explorer 1500 v2 is sealed at 1,536Wh — fine if that covers you, but it's the ceiling. By contrast the DELTA Pro can add expansion batteries, though the first thing it has over the Explorer 1500 v2 is its own 3,600Wh base — expansion is the step after that, for the buyer who would outgrow 3,600Wh as well.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The Explorer 1500 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. Worth saying because the per-dollar framing can suggest otherwise: the Explorer 1500 v2 works out at 5.3 years of cover per $1,000 spent against the DELTA Pro's 2.6, but that spread is the price gap, not the terms.
Full record above — the Test Desk pick is the DELTA Pro.

Analyst note
Both units cost the same to own over their rated lives — $0.15/kWh each. Lifetime cost can't separate them, so decide on the sticker price and everything else. 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 still delivers more over its shorter horizon (12,600 vs 6,144 kWh). Years measure wear, not usefulness.

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 Pro
EXPANDABLESupports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 3,600Wh.
Accepts up to 1,600W of solar. Enough for a serious multi-panel array.
Generous port selection supports complex multi-device setups.
Expansion batteries are EcoFlow-specific. You're investing in the EcoFlow ecosystem.
Explorer 1500 v2
FIXED CAPACITYFixed at 1,536Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 400W of solar. Suitable for a 1-2 panel setup.
Adequate ports for most setups, but heavy users may want a power strip.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
The Explorer 1500 v2 is sealed at 1,536Wh, which is fine if that covers you. The DELTA Pro starts at 3,600Wh 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.
The Bottom Line
The full picture comes down to this. The DELTA Pro 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 1500 v2 wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the DELTA Pro nor the Explorer 1500 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.
Is the DELTA Pro worth $950 more than the Explorer 1500 v2?
The short answer: yes, if you'll actually use the extra capability. The DELTA Pro costs $950 more, but that premium buys you 2,064Wh more battery capacity (that's 12 extra hours of running a mini-fridge); 1,600W higher AC output (opening the door to more demanding appliances); 1,200W faster solar charging for quicker off-grid recovery. On a cost-per-watt-hour basis, you're paying $0.53/Wh vs $0.62/Wh. For regular use, we'd pay the premium.
How does the 2,064Wh capacity difference actually affect daily use?
The DELTA Pro's 3,600Wh battery keeps a mini-fridge running for roughly 20 hours vs the Explorer 1500 v2's 9 hours. Where it really matters: during an 8-hour blackout running your fridge, router, lights, AND charging your phone simultaneously (about 1,645Wh total), the DELTA Pro handles it while the Explorer 1500 v2 runs dry. What specs don't mention: runtime drops 20-30% in cold weather (below 32°F/0°C) as battery chemistry slows down. The DELTA Pro'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 Pro, or is the Explorer 1500 v2 the only portable option?
Neither is "portable" in any hiking sense. The Explorer 1500 v2 (32 lbs) and the DELTA Pro (99 lbs) are both appliances you place and leave. The 67-lb difference matters when loading into a vehicle or moving between rooms, but that's about it. If true portability is your priority, look at units under 20 lbs in a different class entirely.
How fast can each unit recharge from solar panels in real conditions?
On paper, the DELTA Pro accepts 1,600W vs the Explorer 1500 v2's 400W 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 3.2 hours for the DELTA Pro and 5.5 hours for the Explorer 1500 v2. That gap widens on cloudy days, when the DELTA Pro'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 Pro's advantage is substantial.
What if I need more capacity than the Explorer 1500 v2's 1,536Wh later?
The Explorer 1500 v2 is sealed at 1,536Wh, so if you expect your needs to climb, the DELTA Pro is the more future-proof pick: it starts at 3,600Wh and adds EcoFlow-compatible batteries without replacing the base unit. That said, "not expandable" isn't a flaw on its own — if 1,536Wh comfortably covers your loads, the Explorer 1500 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 Pro or the Explorer 1500 v2?
We'd pay the premium for the DELTA Pro. 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 1500 v2 is still solid if budget is the priority, but the DELTA Pro will leave you less likely to wish you'd "gone bigger" six months from now. That regret costs more than the price difference.
