Spec deltas
The EcoFlow DELTA Pro costs $1,399 and holds 3,600Wh. The BLUETTI Apex 300 costs $1,799 and holds 2,764.8Wh. That's the Apex 300 asking $400 more for less capacity. What it does get back is weight — 83.78 lbs against 99.
Both are expandable and both carry a 5-year warranty, though the Apex 300 is rated for 6,000 cycles against the DELTA Pro's 3,500, which is enough to level the lifetime-cost column. It's a straightforward value argument otherwise, and on price and capacity together, the DELTA Pro wins clean.
Where the Apex 300 earns its premium: a 2,400W solar ceiling against the DELTA Pro's 1,600W, and a fan that stays at 45dB where the DELTA Pro's known noise complaint runs a full 15dB louder. Neither is nothing, but neither closes a $400 gap by itself.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
Run it as cost per lifetime kWh and the gap closes rather than widens: $0.11 for each of them, because the Apex 300's 6,000 rated cycles against 3,500 spread its higher price across more energy. The DELTA Pro is cheaper on day one and level from there.
The DELTA Pro costs $1,399 with 3,600Wh capacityThe Apex 300 costs $1,799 with 2,764.8Wh capacity
Why it mattersA buyer optimizing purely for value per watt-hour should default to the DELTA Pro without needing another data point.
A reviewer who found the Apex 300 impossible to lift onto a table aloneB8 is describing a heavier unit than the one whose worst-case complaint is 'needs a cart on gravel.' The portability gap favors the DELTA Pro even accounting for both units' known weight friction.
The DELTA Pro weighs 99 lbs; the Apex 300 weighs 83.78 lbsOwners describe the DELTA Pro-line as wheeled and manageable on flat ground but needing a cart on uneven terrainA2
Why it mattersAnyone moving the station in and out of a vehicle regularly should weight the DELTA Pro's lighter build over the Apex 300's expansion port.
solar input
For an off-grid setup running near its ceiling for hours at a stretch — the exact case where solar speed matters — the Apex 300's quieter fan and higher solar ceiling work together, not separately, to make it the more livable choice despite the price and weight penalty.
The Apex 300 accepts up to 2,400W of solar input against the DELTA Pro's 1,600WThe Apex 300 runs at 45dB under load; DELTA Pro-line testing found a distracting high-pitched whine above 2,000W drawA4
Why it mattersOff-grid buyers who'll routinely run near full load should weigh the Apex 300's combined solar-and-noise advantage against its $400 premium; everyone else should bank the savings.
Add the $300 Hub D1 to get functional ports and the effective price gap over the DELTA Pro isn't $400 — it's closer to $700 before you've bought a single expansion battery for either unit.
Both units support expansion batteries and carry a 2,400W (Apex 300) versus 1,600W (DELTA Pro) solar ceilingThe Apex 300 requires a separate $300 Hub D1 accessory just to expose USB and DC ports on the front faceB7B11
Why it mattersBuyers comparing sticker prices should price in the Hub D1 before deciding the Apex 300's extra solar ceiling is worth the premium.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: Lifetime cost lands level at $0.11 each, which takes the page's biggest assumed gap off the table.
cost / lifetime kWh
Four hundred dollars cheaper and holding more energy — the DELTA Pro's $1,399 for 3,600Wh against the Apex 300's $1,799 for 2,764.8Wh is a lopsided trade before either unit runs a single cycle. Spread it over a full service life and the gap closes rather than grows: $0.11 per lifetime kWh each, because the Apex 300 is rated for 6,000 cycles against the DELTA Pro's 3,500. Buy this one on the sticker, not on the per-kWh math.
That's not a rounding difference between two similarly-priced units. It's the DELTA Pro doing more total work for less money across every dollar you spend on it, full stop.
Portability & Form Factor
Selected because: 83.78 lbs vs 99 lbs, with the wheels on the heavier unit, is what actually decides daily handling.
weight
Ninety-nine pounds against 83.78 — the DELTA Pro is the heavier unit, and its own field reports flag it as heavy enough to need a cart on uneven groundA2. What it has that the Apex 300 doesn't is wheels, which is worth more than fifteen pounds on smooth ground and nothing at all on stairs.
One Apex 300 reviewer couldn't lift it onto a table soloB8; DELTA Pro owners, by comparison, describe it as manageable on flat, smooth ground with its integrated wheels and telescoping handleA2. Neither is a light unit. One of them at least rolls.
Your Life, Your Pick
Selected because: DELTA Pro wins Weekend Camping and the 8-Hour Blackout with real margin.
The DELTA Pro wins Weekend Camping using 69% of its tank against the Apex 300's 89%, and the 8-Hour Blackout at 54% against 70%. Both units clear the bar, but the DELTA Pro does it with noticeably more capacity to spare.
CPAP Overnight, Remote Workday, and Tailgate Party all come back as ties, and Van Life Daily beats both — so the decision really does live in those two scenarios, and the DELTA Pro owns the margin in each.
What the Specs Don't Tell You
Selected because: Weight and noise both fire, and the Apex 300's Hub D1 add-on cost belongs in the honest-catch conversation.
rated cycles
Both units have a documented noise problem, just at different moments: the DELTA Pro-line gets a distracting whine above roughly 2,000W of drawA4, while the Apex 300 stays at a comparatively tame 45dB across its rated load. If you routinely push either unit hard, that's worth weighing over the raw price gap.
The honest catch on the Apex 300: its $1,799 price doesn't include working front-facing ports. The Hub D1 that adds them runs about $300 moreB7B11, which means the real gap to the DELTA Pro is closer to $700 once you configure the Apex 300 the way most buyers will actually want it.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Apex 300
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 Apex 300 is rated 45dB against the DELTA Pro's 60dB. 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.

Game day power for the crew
Either unit
Both handle game day easily. Since capacity isn't the deciding factor, weight is: at 83.8 lbs the Apex 300 is the one you'll be glad you brought. Fan noise under load is worth a listen too — it's audible in the lulls between songs.

Conclusion
July 15, 2026
Verdict: the EcoFlow DELTA Pro
At $1,399 against $1,799, the DELTA Pro undercuts the Apex 300 by $400 while offering more capacity — 3,600Wh against 2,764.8Wh. It wins every scenario where the two diverge, from Weekend Camping to the 8-Hour Blackout, and it rolls on its own wheels. On lifetime cost the two are level at $0.11 per kWh, because the Apex 300's 6,000 rated cycles against 3,500 offset its higher price. The Apex 300 also answers with 15.2 lbs less to lift, a quieter fan under load, a higher solar ceiling, and BLUETTI's generally tighter app experience — real, but not enough to close a $400 gap on a unit that's already winning the capacity number and the scenarios.
Today the Apex 300 is $1,499, $200 under its typical $1,699. The verdict weighs typical prices, not today's. Prices checked 1 day ago.

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 rates 3.9/5 (33rd 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.
99 lbs vs 83.78, With a Caveat on Both
The DELTA Pro is the lighter unit by a wide margin, though its own field reports note it needs a cart on uneven ground. The Apex 300 starts from a heavier baseline with no wheels of its own.
Two Different Noise Problems
The DELTA Pro-line's noise complaint shows up above roughly 2,000W of draw. The Apex 300 stays quieter at 45dB across its rated load — the tradeoff runs the other direction from what the weight numbers suggest.
10ms vs 20ms Switchover
The Apex 300's 10ms UPS switchover is twice as fast as the DELTA Pro's 20ms. For most electronics the difference is invisible; for equipment sensitive to even a brief power gap, it isn't.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. 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.
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 3,600Wh on the DELTA Pro, so count lifetime energy — roughly 16,589 kWh against 12,600 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.

Brand trust
EcoFlow
Ecosystem
Largest in portable power — 12-15 models across DELTA Pro, DELTA 3, and RIVER 3 series, plus solar panels and smart home panels
Support
US-based phone/email/chat support (1-800-368-8604). Experiences are polarized — many report hassle-free prepaid-label replacements, but others report long waits and refurbished units sent for new claims. Pro tip: buying from Costco or Amazon gives you a stronger return safety net.
Community
Largest community in the space — Reddit r/Ecoflow_community (~31K members), multiple Facebook groups, and an official community forum
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.
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.

Analyst note
Both expand, but the Apex 300's higher solar ceiling (2,400W vs 1,600W) gives it the stronger off-grid growth path — more panels can feed a bigger bank as it grows.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA Pro
The DELTA Pro has a long track record as a home-backup workhorse: reviewers describe it running fridges, lighting, and a space heater through multiple overnight outages over months, backed by an LFP battery rated for a decade-plus of daily useA1A3. That's a different kind of evidence than a fresh-out-of-the-box unboxing review, and it's consistently positive.
The one recurring complaint is noise under heavy load — a high-pitched whine above roughly 2,000W that's distracting in a quiet room, though it's quiet enough at lighter drawsA4. Coverage worth flagging: much of the available field data blends the original DELTA Pro with the newer, heavier DELTA Pro 3, so treat specific weight and dB figures for this exact model with some caution.
“Long regarded as a gold standard for home backup — designed for high-draw appliances and full-scale battery expansion, running home essentials like a fridge, lighting, and a space heater through outages.”

BLUETTI Apex 300
The Apex 300's real cost of ownership shows up in accessories, not the sticker price. Multiple reviewers flag the $300 Hub D1 needed just to get working USB and DC ports on the front faceB7B11, and a further $699 Hub A1 if you want to link multiple units in parallelB12 — costs that never show up in the $1,799 headline figure.
On the hardware itself, opinion splits by degree rather than direction: one reviewer called the fans relatively tame for the unit's sizeB5, while another couldn't lift it onto a table aloneB8. A separate, more consistent thread describes firmware updates causing mode-lock issues, charging errors, and Bluetooth disconnectsB1B2B3 — worth watching for at update time, not treating as a hardware flaw.

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.
Who Should Buy Which
Buy the DELTA Pro if you…
- →Buyers optimizing purely for capacity per dollar and the lower price today
- →Home-backup shoppers who want a proven, long-track-record platform over a newer design
- →Anyone moving the unit regularly who wants the lighter build, even with its own cart caveat on rough ground
Buy the Apex 300 if you…
- →Off-grid buyers running near full load for hours who need the quieter 45dB fan and higher 2,400W solar ceiling
- →Buyers who've already budgeted for the Hub D1 and want BLUETTI's modular port system
- →Anyone prioritizing surge headroom for hard-starting compressor loads over raw price
If neither fits
Van Life Daily's roughly 4,685Wh need beats both units outright — the DELTA Pro covers about 153% of its own tank against that load and the Apex 300 about 199%, so anyone living off one of these full-time needs a larger home-backup-class system instead.
The Bottom Line
Take the DELTA Pro unless you have a specific reason not to: it's $400 cheaper, holds more energy, rolls on its own wheels, and wins both scenarios that actually separate the two. On lifetime cost the pair are level at $0.11 per kWh, and weight goes the Apex 300's way by 15.2 lbs.
The Apex 300 earns its premium only for off-grid buyers running near full load who value the quieter fan and the higher solar ceiling enough to also absorb the Hub D1's real add-on cost. Everyone else should bank the $400.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow DELTA Pro or BLUETTI Apex 300 the better value?
The DELTA Pro, on the numbers most buyers use — it costs $400 less and holds more capacity, 3,600Wh against 2,764.8Wh. Per lifetime kWh they're level at $0.11 each, since the Apex 300's 6,000 rated cycles offset its higher price. The Apex 300 closes the rest of the gap only if its quieter fan, lighter chassis or higher solar ceiling are worth the premium to you specifically.
Which one is quieter under heavy load?
The Apex 300, at a rated 45dB against the DELTA Pro-line's reported high-pitched whine above roughly 2,000W of draw. If the unit will sit in a bedroom or a quiet room while running hard, that gap matters more than the price difference.
Do I need to budget for extra accessories with either unit?
Mainly with the Apex 300. Its front face doesn't include working USB and DC ports out of the box — those require the separate Hub D1, priced around $300 — while the DELTA Pro's ports are built in at the $1,399 price. Factor that in before comparing the two sticker prices directly.
Which one charges faster from solar?
The Apex 300, with a 2,400W solar ceiling against the DELTA Pro's 1,600W. That advantage matters most for off-grid buyers who regularly run the unit down and need to refill it from panels rather than a wall outlet.
