Spec deltas
The EcoFlow DELTA 3 1500 (1,536Wh) and Jackery HomePower 3600 Pro Max (3,584Wh) 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 HomePower 3600 Pro Max 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 HomePower 3600 Pro Max's 4,000W inverter has the headroom for a window AC, a full-size fridge, and power tools. The DELTA 3 1500's 1,800W inverter still runs most single appliances; the HomePower 3600 Pro Max's real edge is surge headroom for the biggest motor starts and stacking several heavy loads at once. On stamina, the HomePower 3600 Pro Max keeps a fridge alive for roughly 20 hours vs the DELTA 3 1500's 9 hours. The cost? Portability. At 73.9 lbs, the HomePower 3600 Pro Max is heavy enough to make you think twice about moving it. The DELTA 3 1500 at 36 lbs is something one person can actually carry.
Pick the HomePower 3600 Pro Max if your primary use is weekend camping or 8-hour blackout. Go with the DELTA 3 1500 if you want the option to add expansion batteries later. 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
- +Lighter by 37.8 lb
Trade-offs
- –Weaker inverter (-2,200W) limits appliance compatibility.
- –Shorter-lived battery — rated for 3,000 charge cycles vs the HomePower 3600 Pro Max's 6,000, so it wears out sooner.
Jackery HomePower 3600 Pro Max
With a massive 4,000W output (and 8,000W surge), the HomePower 3600 Pro Max can run high-wattage appliances like space heaters, hair dryers, and electric grills without tripping. Weighing in at 73.9 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 $0.50 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
- +Rated for 6,000 charge cycles — much longer battery lifespan
Trade-offs
- –Significantly heavier (+37.8 lbs), making it harder to move.

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. What would separate them is fan noise, but DELTA 3 1500 doesn't publish a figure, so there's nothing to hold it to. Only the HomePower 3600 Pro Max is still sold, so for a new buy it takes this by default; the DELTA 3 1500 is worth weighing on weight and fan noise only if you already own one.

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 HomePower 3600 Pro Max rates 4.3/5 (58th percentile of 20 Home Backup-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.
HomePower 3600 Pro Max: 73.9 lbs Is a Commitment
At 73.9 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.
UPS Switchover: ≤10ms vs ≤15ms
Both list a UPS mode, at different rated speeds. The HomePower 3600 Pro Max is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. 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. 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 HomePower 3600 Pro Max'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 HomePower 3600 Pro Max 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 3,584Wh on the HomePower 3600 Pro Max and 1,536Wh on the DELTA 3 1500, so count lifetime energy — roughly 21,504 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 HomePower 3600 Pro Max 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 HomePower 3600 Pro Max'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.
Full record above — the Test Desk pick is the HomePower 3600 Pro Max.

Analyst note
The DELTA 3 1500 is no longer sold, so there is no price to work its cost per kWh from, and this comparison doesn't quote one. On what you can actually buy today, the HomePower 3600 Pro Max works out at $0.08/kWh over its rated life. If you already own the DELTA 3 1500, the hardware comparison still holds: over its rated life the DELTA 3 1500 delivers about 4,608 kWh and the HomePower 3600 Pro Max about 21,504 kWh.
Brand trust

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.

Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Growth only counts if you can still buy in, and the DELTA 3 1500 is no longer sold (EcoFlow points owners to the DELTA 3 Max). That leaves the HomePower 3600 Pro Max: it starts at 3,584Wh and takes Jackery expansion batteries, so the ceiling moves if your needs do. The DELTA 3 1500's expandability still matters if you already own one, but it isn't a reason to pick it over the HomePower 3600 Pro Max.
The Bottom Line
The full picture comes down to this. The HomePower 3600 Pro Max 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 DELTA 3 1500 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 HomePower 3600 Pro Max 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 2,048Wh capacity difference actually affect daily use?
The HomePower 3600 Pro Max's 3,584Wh battery keeps a mini-fridge running for roughly 20 hours vs the DELTA 3 1500'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 HomePower 3600 Pro Max handles it while the DELTA 3 1500 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 HomePower 3600 Pro Max'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 HomePower 3600 Pro Max, or is the DELTA 3 1500 the only portable option?
Neither is "portable" in any hiking sense. The DELTA 3 1500 (36 lbs) and the HomePower 3600 Pro Max (73.9 lbs) are both appliances you place and leave. The 37.8-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 HomePower 3600 Pro Max accepts 1,200W vs the DELTA 3 1500's 500W 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 4.3 hours for the HomePower 3600 Pro Max and 4.4 hours for the DELTA 3 1500. That gap widens on cloudy days, when the HomePower 3600 Pro Max'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 HomePower 3600 Pro Max's advantage is substantial.
"6,000 vs 3,000 cycles" — what does that actually mean for me?
In real years: the HomePower 3600 Pro Max (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 3,584Wh unit becomes a ~2,867Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
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 HomePower 3600 Pro Max?
We'd buy the HomePower 3600 Pro Max. The DELTA 3 1500 is no longer sold, so there is no price to weigh it against; the comparison on this page still helps if you own one.
