No longer sold
Jackery no longer sells the Explorer 2000 Plus as a standalone unit — the listing now carries only kits, the add-on battery and a refurbished unit. Its successor in the line is the HomePower 2000 Plus v2: the same 2 kWh class with a 2,400W inverter in the newer design.
HomePower 2000 Plus v2 · $1,199.00Spec deltas
The EcoFlow DELTA Pro Ultra + 2 Batteries (18,432Wh) and Jackery Explorer 2000 Plus (2,043Wh) 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 Ultra + 2 Batteries 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 Ultra + 2 Batteries's 7,200W inverter has the headroom for a window AC, a full-size fridge, and power tools. The Explorer 2000 Plus's 3,000W inverter still runs most single appliances; the DELTA Pro Ultra + 2 Batteries's real edge is surge headroom for the biggest motor starts and stacking several heavy loads at once. On stamina, the DELTA Pro Ultra + 2 Batteries keeps a fridge alive for roughly 104 hours vs the Explorer 2000 Plus's 12 hours. The cost? Portability. At 405.4 lbs, the DELTA Pro Ultra + 2 Batteries is spread across boxes you site once and leave. The Explorer 2000 Plus at 61.5 lbs is more manageable, though still not light.
Pick the DELTA Pro Ultra + 2 Batteries if your primary use is 8-hour blackout or remote workday. Go with the Explorer 2000 Plus if you primarily need it for tailgate party. Cost to own runs close here — about $0.11/kWh for the Explorer 2000 Plus against $0.12 for the DELTA Pro Ultra + 2 Batteries — 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.

We ran the math on six real-world scenarios. Here's which unit survives your actual life.
SCN-01 · 2 nights · needs 2,100Wh
Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Neither gives you a powered weekend: the DELTA Pro Ultra + 2 Batteries has the energy but doesn't travel, and the Explorer 2000 Plus covers about 83% of the 2,100Wh. One can't go; the other can't finish.

8-Hour Blackout
Keep the essentials running through a night without power
DELTA Pro Ultra + 2 Batteries
Both survive the night. The DELTA Pro Ultra + 2 Batteries finishes at 10% used with 14,022Wh left — 8.5 more nights like it. The Explorer 2000 Plus finishes at 95% with 91Wh, 6% of a second night. If your outages tend to run past one evening, that difference is the whole argument between them.

SCN-03 · 8 hours · needs 320Wh
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 many times over and the capacity margin is a formality. Both happen to list 30dB — two makers' own figures landing on the same number rather than a measured tie — so there is nothing in the noise column to separate them either. Buy whichever is cheaper or easier to carry.

Explorer 2000 Plus
The DELTA Pro Ultra + 2 Batteries at 405.4 lbs is not a take-along — it rolls off a truck bed if it travels at all, so this scenario belongs to the Explorer 2000 Plus by default — and it earns it, covering the 670Wh with 1,066Wh to spare. Capacity was never the DELTA Pro Ultra + 2 Batteries's problem here; getting to a tailgate was.

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 Ultra + 2 Batteries rates 3.8/5 (29th percentile of 29 Whole-Home / Off-Grid-class units), and Explorer 2000 Plus rates 4.5/5 (68th percentile of 26 Large-class units).

Weight Reality Check
Neither unit is grab-and-go. The Explorer 2000 Plus (61.5 lbs) is manageable solo but heavier than a large checked suitcase. The DELTA Pro Ultra + 2 Batteries (405.4 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's a 344 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.
Surge Power: Ratio and Ceiling Disagree
The Explorer 2000 Plus holds the higher surge-to-continuous ratio (2× vs 1.5×), but the DELTA Pro Ultra + 2 Batteries holds the higher absolute surge ceiling — 10,800W against 6,000W. 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 Pro Ultra + 2 Batteries is the stronger unit here — while the Explorer 2000 Plus is the one running further below its own limit at steady state.
UPS Switchover: 0ms-rated vs ≤20ms
Both list a UPS mode, at different rated speeds. The DELTA Pro Ultra + 2 Batteries is rated 0ms — a no-break design on paper, which is the maker's classification rather than a stopwatch result. The Explorer 2000 Plus 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: 10 Years vs 5
The DELTA Pro Ultra + 2 Batteries is covered for 10 years against the Explorer 2000 Plus's 5 years. The cheaper Explorer 2000 Plus does buy more warranty per dollar (5.6 years per $1,000 against 1.3), but that is a statement about price, not about coverage — if a fault appears in year 6, only one of these is still covered. The Explorer 2000 Plus'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. An underrated factor if you're keeping this unit for years.

Analyst note
Both units have similar long-term ownership costs ($0.12/kWh vs $0.11/kWh). The price difference is what you see on the sticker — neither is a hidden bargain or rip-off. One caution on the lifespan row: the Explorer 2000 Plus takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the DELTA Pro Ultra + 2 Batteries still delivers more over its shorter horizon (64,512 vs 8,171 kWh). Years measure wear, not usefulness.

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.

Analyst note
Both expand, but the DELTA Pro Ultra + 2 Batteries's higher solar ceiling (5,600W vs 1,200W) gives it the stronger off-grid growth path — more panels can feed a bigger bank as it grows.
The Bottom Line
The full picture comes down to this. The DELTA Pro Ultra + 2 Batteries 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 2000 Plus wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the DELTA Pro Ultra + 2 Batteries nor the Explorer 2000 Plus feels like the right fit, your power needs probably sit outside what these two target. For lighter use — weekend camping or phone/laptop charging — you'd be overpaying for capacity you'll rarely tap. Consider a unit in the 500–1,500Wh range instead. 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 Ultra + 2 Batteries worth $7,100 more than the Explorer 2000 Plus?
The short answer: yes, if you'll actually use the extra capability. The DELTA Pro Ultra + 2 Batteries costs $7,100 more, but that premium buys you 16,389.2Wh more battery capacity (that's 93 extra hours of running a mini-fridge); 4,200W higher AC output (opening the door to more demanding appliances); 4,400W faster solar charging for quicker off-grid recovery. On a cost-per-watt-hour basis, you're paying $0.43/Wh vs $0.44/Wh. For regular use, we'd pay the premium.
How does the 16,389.2Wh capacity difference actually affect daily use?
The DELTA Pro Ultra + 2 Batteries's 18,432Wh battery keeps a mini-fridge running for roughly 104 hours vs the Explorer 2000 Plus's 12 hours. Both can handle a full 8-hour blackout setup (fridge + router + lights + phone charging ≈ 1,645Wh), but the DELTA Pro Ultra + 2 Batteries finishes with significantly more margin. That matters if conditions aren't ideal or the outage runs long. 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 Ultra + 2 Batteries'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 Ultra + 2 Batteries, or is the Explorer 2000 Plus the only portable option?
Neither is "portable" in any hiking sense. The Explorer 2000 Plus (61.5 lbs) and the DELTA Pro Ultra + 2 Batteries (405.4 lbs) are both appliances you place and leave. The 343.9-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 Ultra + 2 Batteries accepts 5,600W vs the Explorer 2000 Plus's 1,200W 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 4.7 hours for the DELTA Pro Ultra + 2 Batteries and 2.4 hours for the Explorer 2000 Plus. That gap widens on cloudy days, when the DELTA Pro Ultra + 2 Batteries'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 Ultra + 2 Batteries's advantage is substantial.
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 Pro Ultra + 2 Batteries or the Explorer 2000 Plus?
We'd pay the premium for the DELTA Pro Ultra + 2 Batteries. 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 2000 Plus is still solid if budget is the priority, but the DELTA Pro Ultra + 2 Batteries will leave you less likely to wish you'd "gone bigger" six months from now. That regret costs more than the price difference.
