Spec deltas
The EcoFlow DELTA Pro Ultra (6,144Wh) and BLUETTI Apex 300 (2,765Wh) 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 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's 7,200W inverter has the headroom for a window AC, a full-size fridge, and power tools. The Apex 300's 3,840W inverter still runs most single appliances; the DELTA Pro Ultra's real edge is surge headroom for the biggest motor starts and stacking several heavy loads at once. On stamina, the DELTA Pro Ultra keeps a fridge alive for roughly 35 hours vs the Apex 300's 16 hours. The cost? Portability. At 181.8 lbs, the DELTA Pro Ultra is a two-person lift you set down once and leave. The Apex 300 at 83.8 lbs is more manageable, though still not light.
Pick the DELTA Pro Ultra if your primary use is 8-hour blackout or cpap overnight. Go with the Apex 300 if you primarily need it for weekend camping or tailgate party. Most buyers stop at the sticker price and miss this: over a full lifespan the Apex 300 works out to about $0.1/kWh against the DELTA Pro Ultra's $0.2, a gap that compounds in the Apex 300'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 Pro Ultra
With a massive 7,200W output (and 10,800W surge), the DELTA Pro Ultra can run high-wattage appliances like space heaters, hair dryers, and electric grills without tripping. Weighing in at 181.8 lbs, this is not a unit you want to carry far. It's best suited as a stationary backup or RV companion.
Strengths
- +Larger battery capacity
- +Higher AC output
- +Longer warranty
- +Faster solar charging
Trade-offs
- –Substantially more expensive (+$2,500) than the Apex 300.
- –Significantly heavier (+98 lbs), making it harder to move.
- –Very heavy unit that may be difficult for one person to lift.
- –Shorter-lived battery — rated for 3,500 charge cycles vs the Apex 300's 6,000, so it wears out sooner.
BLUETTI Apex 300
With a massive 3,840W output (and 7,680W surge), the Apex 300 can run high-wattage appliances like space heaters, hair dryers, and electric grills without tripping. Weighing in at 83.8 lbs, this is not a unit you want to carry far. It's best suited as a stationary backup or RV companion.
Strengths
- +Costs $2,500 less
- +Lighter by 98 lb
- +Rated for 6,000 charge cycles — much longer battery lifespan
Trade-offs
- –Weaker inverter (-3,360W) limits appliance compatibility.

Scenario verdicts
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
Apex 300
The DELTA Pro Ultra at 181.8 lbs is not a take-along — it rolls off a truck bed if it travels at all, so this scenario belongs to the Apex 300 by default — and it earns it, covering the 2,100Wh with 250Wh to spare. Capacity was never the DELTA Pro Ultra's problem here; getting to a campsite was.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
DELTA Pro Ultra
Both survive the night. The DELTA Pro Ultra finishes at 31% used with 3,577Wh left — 2.2 more nights like it. The Apex 300 finishes at 70% with 705Wh, 43% 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
DELTA Pro Ultra
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 DELTA Pro Ultra is rated 30dB against the Apex 300's 45dB. 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.

DELTA Pro Ultra
The DELTA Pro Ultra clears the workday at 17% used, banking 4,312Wh — late work, extra calls, or a second laptop charge without arithmetic. The Apex 300 at 39% also finishes, with 1,440Wh of slack for the unplanned.

Apex 300
The DELTA Pro Ultra at 181.8 lbs is not a take-along — it rolls off a truck bed if it travels at all, so this scenario belongs to the Apex 300 by default — and it earns it, covering the 670Wh with 1,680Wh to spare. Capacity was never the DELTA Pro Ultra's problem here; getting to a tailgate was.

Runtime model
Runtime = (rated capacity × 0.85 inverter efficiency) ÷ device wattage. Solar recharge estimates assume panels deliver 70% of rated output. Cold weather, battery age, and stacked loads reduce real-world results.
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 Pro Ultra rates 4.9/5 (93rd percentile of 16 Home Backup-class units), and Apex 300 rates 5.0/5 (99th percentile of 26 Large-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Weight Reality Check
Neither unit is grab-and-go. The Apex 300 (83.8 lbs) is manageable solo but heavier than a large checked suitcase. The DELTA Pro Ultra (181.8 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's a 98 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.
Apex 300: 45dB Published
45dB is about as loud as a running refrigerator. The DELTA Pro Ultra 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.
Surge Power: Ratio and Ceiling Disagree
The Apex 300 holds the higher surge-to-continuous ratio (2× vs 1.5×), but the DELTA Pro Ultra holds the higher absolute surge ceiling — 10,800W against 7,680W. 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 is the stronger unit here — while the Apex 300 is the one running further below its own limit at steady state.
UPS Switchover: 0ms-rated vs ≤10ms
Both list a UPS mode, at different rated speeds. The DELTA Pro Ultra is rated 0ms — a no-break design on paper, which is the maker's classification rather than a stopwatch result. The Apex 300 is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. 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 is covered for 10 years against the Apex 300's 5 years. The Apex 300's figure is a maximum rather than a guarantee — it depends on buying direct from BLUETTI or registering the unit, since reseller purchases carry a shorter term. An underrated factor if you're keeping this unit for years.
Battery Lifespan in Real Years
The Apex 300 is rated for 6,000 cycles vs 3,500. In real life: at daily use, that's 16.4 vs 9.6 years. At weekend use (twice a week), it's 58 vs 34 years. One caution reading years across different sizes: a cycle is 2,765Wh on the Apex 300 and 6,144Wh on the DELTA Pro Ultra, so count lifetime energy — roughly 16,589 kWh against 21,504 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.

Analyst note
The Apex 300 wins on both sticker price and long-term value. At $0.1/kWh over its lifetime, it's meaningfully cheaper to own. Clear value winner. One caution on the lifespan row: the Apex 300 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the DELTA Pro Ultra still delivers more over its shorter horizon (21,504 vs 16,589 kWh). Years measure wear, not usefulness.

App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
Fastest-charging technology (X-Stream), deepest product ecosystem, and most active innovation cadence. At the very top of the range, the DELTA Pro Ultra platform stacks batteries and inverters into whole-home backup — a flagship path, not a line-wide feature.
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.
BLUETTI
Ecosystem
One of the broadest lineups — 15-20+ models from budget (AC2A) to flagship portable (Apex 300, 2764.8Wh). Includes specialized products: vehicle solar hubs, sodium-ion cold-weather units, and balcony storage systems.
Support
The most inconsistent support in the space. Heavily email-based with China timezone delays. Some users get smooth, efficient service; others report weeks of troubleshooting runarounds, being offered discounts on new units instead of repairs, and confusing third-party purchase claim processes. Buying direct from Bluetti's website tends to produce better support outcomes.
Community
Active and growing — Reddit r/bluetti has a dedicated community. Second-largest after EcoFlow in engagement.
App experience
Rated 4.5/5 iOS and Android — tied for best app experience in the category. V3.0 UI redesign was well-received.
Unique strength
Among the best capacity-to-price ratios available — several Elite and Apex units are the lowest $/Wh in the catalog. Widest product diversity including industry-firsts like sodium-ion cold-weather units and dual solar+alternator vehicle hubs. LFP across the rest of the range, though rated cycle life spans 2,500 (EB3A) to 6,000, and it varies WITHIN the Elite range rather than tracking it — the Elite 300 and Elite 200 V2 are rated 6,000 while the Elite 30 V2, Elite 10 Mini, Elite 320 and Elite 400 are rated 3,000+ and the Elite 100 V2 4,000+, so check the specific model. Dual-voltage (120V/240V) in flagships.
Worth knowing
Customer support inconsistency is the #1 risk factor. Older/discontinued units may become unrepairable — no spare parts policy for some models. Some reports of erratic communication from support agents.
Analyst note
EcoFlow positions itself as a mid-to-premium brand with stronger support infrastructure, while BLUETTI competes on value. The question is whether the EcoFlow ecosystem and support premium is worth it for your use case.

Claims are weighted by how specific they are, whether the commenter owns the unit, and how many readers agreed. Comments that mention a product under a rival's review count for more, because the commenter had no reason to be there. This is what buyers report, not our test results — for measurements we ran ourselves, see the methodology.
The Bottom Line
The full picture comes down to this. The DELTA Pro Ultra 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 Apex 300 wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the DELTA Pro Ultra nor the Apex 300 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 BLUETTI 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 worth $2,500 more than the Apex 300?
The short answer: yes, if you'll actually use the extra capability. The DELTA Pro Ultra costs $2,500 more, but that premium buys you 3,379.2Wh more battery capacity (that's 19 extra hours of running a mini-fridge); 3,360W higher AC output (opening the door to more demanding appliances); 3,200W faster solar charging for quicker off-grid recovery. On a cost-per-watt-hour basis, you're paying $0.68/Wh vs $0.61/Wh. For regular use, we'd pay the premium.
How does the 3,379.2Wh capacity difference actually affect daily use?
The DELTA Pro Ultra's 6,144Wh battery keeps a mini-fridge running for roughly 35 hours vs the Apex 300's 16 hours. Both can handle a full 8-hour blackout setup (fridge + router + lights + phone charging ≈ 1,645Wh), but the DELTA Pro Ultra 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'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, or is the Apex 300 the only portable option?
Neither is "portable" in any hiking sense. The Apex 300 (83.8 lbs) and the DELTA Pro Ultra (181.8 lbs) are both appliances you place and leave. The 98-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 accepts 5,600W vs the Apex 300's 2,400W 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 1.6 hours for the DELTA Pro Ultra and 1.6 hours for the Apex 300. That gap widens on cloudy days, when the DELTA Pro Ultra'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's advantage is substantial.
"6,000 vs 3,500 cycles" — what does that actually mean for me?
In real years: the Apex 300 (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 Pro Ultra (3,500 cycles): 9.6 years daily, 34 years weekends, or 146 years twice-monthly. What most people miss: hitting the cycle limit doesn't kill your battery. Capacity drops to about 80%. Your 2,764.8Wh unit becomes a ~2,212Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
Is EcoFlow or BLUETTI 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. BLUETTI: 2-6 years depending on model (up to 10 years on home backup systems). Response times vary significantly. Some reports of units being deemed unrepairable with no parts available for older models. 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 or the Apex 300?
We'd pay the premium for the DELTA Pro Ultra. 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 Apex 300 is still solid if budget is the priority, but the DELTA Pro Ultra will leave you less likely to wish you'd "gone bigger" six months from now. That regret costs more than the price difference.
