Spec deltas
The EcoFlow DELTA 3 1000 Air (960Wh) 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 1000 Air's 500W inverter can't start the heaviest of those — a window AC or a high-surge power tool will trip it. On stamina, the HomePower 3600 Pro Max keeps a fridge alive for roughly 20 hours vs the DELTA 3 1000 Air's 5 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 1000 Air at 22 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 1000 Air if its specific strengths below line up better with your use. Most buyers stop at the sticker price and miss this: over a full lifespan the HomePower 3600 Pro Max works out to about $0.08/kWh against the DELTA 3 1000 Air's $0.11, a gap that compounds in the HomePower 3600 Pro Max'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 3 1000 Air
At 500W, this unit is strictly for personal electronics (phones, laptops) and small CPAP machines. Do not expect to run kitchen appliances. At only 22 lbs, it is exceptionally portable. You can easily carry it one-handed to a campsite or tailgating party. A standout feature is the value proposition: at roughly $0.32 per watt-hour, it's one of the most cost-effective options on the market.
Strengths
- +Costs $1,490 less
- +Lighter by 51.8 lb
- +Faster solar charging
Trade-offs
- –Weaker inverter (-3,500W) 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 8,000,240W 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
- +Longer warranty
- +Rated for 6,000 charge cycles — much longer battery lifespan
Trade-offs
- –Substantially more expensive (+$1,490) than the DELTA 3 1000 Air.
- –Significantly heavier (+51.8 lbs), making it harder to move.

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 carry. That's heavier than a large checked suitcase. Moving it from your car to a campsite requires some effort and flat terrain.
DELTA 3 1000 Air: USB-C Maxes at 18W
The DELTA 3 1000 Air's fastest USB-C port outputs 18W. A MacBook Air needs 30W minimum, a MacBook Pro needs 96W, and most USB-C laptops need at least 60W for full-speed charging. At 18W, your laptop will charge slowly. Under load, it might not charge at all. The HomePower 3600 Pro Max handles this at 100W.
DELTA 3 1000 Air: Fixed Capacity
The DELTA 3 1000 Air is sealed at 960Wh — fine if that covers you, but it's the ceiling. The HomePower 3600 Pro Max starts at 3,584Wh and can add expansion batteries, so if your needs may climb toward partial-home backup, it has room to grow the DELTA 3 1000 Air doesn't.
Warranty Value Comparison
The DELTA 3 1000 Air gives you 6.5 years of warranty per $1,000 spent, vs the HomePower 3600 Pro Max's 2.8 years. That's 2.3× more coverage per dollar. An underrated factor if you're keeping this unit for years.
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. After hitting the cycle limit, the battery doesn't die. It drops to ~80% original capacity, which is still very usable.

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 1000 Air
FIXED CAPACITYFixed at 960Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 500W of solar. Suitable for a 1-2 panel setup.
Adequate ports for most setups, but heavy users may want a power strip.
HomePower 3600 Pro Max
EXPANDABLESupports Jackery expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 3,584Wh.
No solar input available.
Limited ports. You'll likely need a power strip or splitter.
Expansion batteries are Jackery-specific. You're investing in the Jackery ecosystem.
Analyst note
The DELTA 3 1000 Air is sealed at 960Wh, which is fine if that covers you. The HomePower 3600 Pro Max starts at 3,584Wh and can grow beyond it with Jackery expansion batteries — real headroom the DELTA 3 1000 Air doesn't have if your needs climb toward partial-home backup.
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 1000 Air wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the DELTA 3 1000 Air 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.
Is the HomePower 3600 Pro Max worth $1,490 more than the DELTA 3 1000 Air?
The short answer: yes, if you'll actually use the extra capability. The HomePower 3600 Pro Max costs $1,490 more, but that premium buys you 2,624Wh more battery capacity (that's 15 extra hours of running a mini-fridge); 3,500W higher AC output (opening the door to more demanding appliances); a longer-lasting battery rated for 6,000 cycles — that's 16 years at daily use. On a cost-per-watt-hour basis, you're paying $0.50/Wh vs $0.32/Wh. Factor in cycle life and the math flips: the HomePower 3600 Pro Max costs $0.08/kWh over its lifetime vs $0.11/kWh. The "expensive" unit is actually cheaper to own. For regular use, we'd pay the premium.
How does the 2,624Wh 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 1000 Air's 5 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 1000 Air 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 1000 Air the only portable option?
At 22 lbs, the DELTA 3 1000 Air is manageable for one person over short distances: parking lot to campsite, trunk to tailgate. The HomePower 3600 Pro Max at 73.9 lbs? You'll want a buddy, a wagon, or wheels. For reference, 73.9 lbs is about the weight of a bag of concrete. If your use case involves any carrying, the DELTA 3 1000 Air wins decisively.
How fast can each unit recharge from solar panels in real conditions?
On paper, the DELTA 3 1000 Air accepts 500W vs the HomePower 3600 Pro Max's 0W 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 2.7 hours for the DELTA 3 1000 Air and N/A hours for the HomePower 3600 Pro Max. That gap widens on cloudy days, when the DELTA 3 1000 Air'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 1000 Air'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 1000 Air (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.
What if I need more capacity than the DELTA 3 1000 Air's 960Wh later?
The DELTA 3 1000 Air is sealed at 960Wh, so if you expect your needs to climb, the HomePower 3600 Pro Max is the more future-proof pick: it starts at 3,584Wh and adds Jackery-compatible batteries without replacing the base unit. That said, "not expandable" isn't a flaw on its own — if 960Wh comfortably covers your loads, the DELTA 3 1000 Air 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 3 1000 Air or the HomePower 3600 Pro Max?
We'd pay the premium for the HomePower 3600 Pro Max. 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 DELTA 3 1000 Air is still solid if budget is the priority, but the HomePower 3600 Pro Max will leave you less likely to wish you'd "gone bigger" six months from now. That regret costs more than the price difference.
