Quick verdict: BLUETTI or EcoFlow?
BLUETTI vs EcoFlow comes down to speed versus value. Pick EcoFlow if fast wall charging, adding batteries later or the best-tested whole-home unit (the DELTA Pro 3) matters most. Pick BLUETTI for more battery and solar input per dollar and a far better complaint record. At 2kWh, prices are nearly identical.
We didn’t test these units; test numbers come from independent labs, and prices and policies from each brand’s US store. For more, see our BLUETTI review and our best portable power stations guide.

Real-world testing: who measured what
OutdoorGearLab’s July 2026 lab tests, which ranked 14 units, are the only head-to-head numbers covering both brands:
- EcoFlow DELTA Pro 3: score 81, second of 14 and the Top Pick for home backup. “Our testers measured 3,790 Wh from its advertised 4,096 Wh,” over 93%. The downside: “This is not the power station to buy if portability is high on your list.” (review)
- EcoFlow DELTA 3: score 67, sixth. It delivered 870Wh and was “a star in our charge speed test,” finishing “even faster than EcoFlow’s own advertised time of 56 minutes.” Its listed con: “Half the AC outlets are ungrounded.” (review)
- BLUETTI Elite 100 V2: score 65, ninth. It delivered more energy than the DELTA 3 (890Wh, 87%) and weighed 3 pounds less, but “the glaring issue with the 100 V2 is its slow charging speed.” (review)
techreviewer.de drew 946Wh (about 93%) from a European Elite 100 V2 at a steady 500W load. Popular Science named the BLUETTI Elite 200 V2 its best overall power station and the Apex 300 best for off-grid living, but published no capacity measurements. We found no independent capacity test of the DELTA 3 Plus, DELTA 3 Max, Elite 200 V2 or Apex 300.

Charging speed: EcoFlow’s clearest win
If you need to top up fast before a storm, EcoFlow is ahead. The DELTA 3 refilled in about 50 minutes in OutdoorGearLab’s test; the Elite 100 V2 took about 2 hours. BLUETTI claims 80% in 45 minutes with its 1,200W TurboBoost mode, but OutdoorGearLab warns that “using this mode regularly will degrade the battery and shorten the power station’s lifespan.”
- 2kWh: Popular Science charged the Elite 200 V2 in “a little over 90 minutes.” EcoFlow claims 0 to 80% in 68 minutes for the DELTA 3 Max; untested.
- Whole-home: the DELTA Pro 3 took 3.2 hours in testing (EcoFlow claims 80% in 50 minutes, setup unstated). The Apex 300’s Turbo AC mode reaches 3,840W, untested.
Solar input: BLUETTI takes more sun in the smaller sizes
In the 1kWh and 2kWh classes BLUETTI takes twice the solar power of the cheaper EcoFlow models:
- Elite 100 V2: 1,000W (12V to 60V). DELTA 3: 500W. The DELTA 3 Plus matches BLUETTI at 1,000W, but costs $220 more.
- Elite 200 V2: 1,000W. DELTA 3 Max: 500W.
- Apex 300: 2,400W through two built-in 1,200W ports (12V to 60V, so panels wire in parallel), or up to 6,400W with the optional SolarX 4K, which needs at least one B300K battery. DELTA Pro 3: 2,600W through a 1,600W high-voltage port (30V to 150V) and a 1,000W low-voltage port.
Warranty and support
Both give 5 years on most of these models. The fine print differs.
- BLUETTI: its warranty table lists 60 months for the Elite 100 V2, Elite 200 V2 and Apex 300. It covers the original buyer in the country of purchase, with “no warranty for gifts product,” and “a refurbished model of equal value may be provided.” The policy doesn’t say who pays to ship a unit in for repair.
- EcoFlow: its US warranty policy starts on the date of delivery and lists 5 years for the DELTA 3, DELTA 3 Plus and DELTA Pro 3 but “3+2 years (Subject to registration)” for the DELTA 3 Max. The DELTA Pro 3’s own page also says 3 + 2, so register either one in the app. Repairs are mail-in, and “EcoFlow will pay for shipping to and from your location if all instructions regarding the method of packaging and shipping the Product are followed” (contiguous US only). If EcoFlow decides a problem isn’t covered, “you must pay all parts, shipping, and labor charges.”
Customer record: both companies have a BBB F, for different reasons. EcoFlow Technology failed to respond to 124 of 127 complaints in three years, and none of its 10 newest complaints (July to September 2026), including failed refurbished replacements and lost shipments, show a response. Bluetti Power left 7 of 37 unanswered, though its replies are mostly templates. On Trustpilot, BLUETTI scores 4.5 from 756 reviews (7% one-star) and EcoFlow 3.6 from 10,588 (24% one-star). To be fair, EcoFlow invites customers to review and replied to 42% of negative reviews; BLUETTI hasn’t invited reviewers recently.
Returns: read the exact wording
- BLUETTI (refund policy): “Within 30 days of the purchase,” items must be “complete, unused and in the original package,” and “you are responsible for the double shipping cost.” It adds: “For products that have been used, we reserve the rights to refuse the return.” Cancel within 48 hours; after shipping there’s a $25 intercept fee.
- EcoFlow (return policy): you may return items “complete in their original packing within 30 days of receiving them,” but “we’ll charge the transaction fee (2.6% for credit card users, 3.6% for PayPal users, 3.5% for Affirm users) + shipping cost.” Its fixed return shipping is $29 for the DELTA 3, $24 for the DELTA 3 Max and $88 for the DELTA Pro 3. By our math, returning a $579 DELTA 3 paid by card costs about $44, and a $2,799 DELTA Pro 3 about $161.
EcoFlow’s version is friendlier: the clock starts when the box arrives, not when you pay, and its policy doesn’t say the unit must be unused. That matters with the Elite 100 V2 not shipping until November 12. For defects, EcoFlow promises “a full refund or one-time free replacement within 30 days of receiving the items.”
Recalls and safety
The CPSC’s full recall list (10,110 recalls through October 22, 2026) has no BLUETTI recall. It has one EcoFlow power station recall: in October 2025 EcoFlow recalled about 25,030 DELTA Max 2000 units (model EFD310, sold July 2022 to May 2025) because they “may overheat and ignite,” after six fires with over $850,000 in property damage. The fix is a free firmware update. No model compared here is affected.
EcoFlow rates the DELTA 3 and DELTA 3 Plus battery packs IP65 and sells the DELTA Pro 3 as UL9540 certified. BLUETTI says the Elite 200 V2 and Apex 300 are not waterproof. All seven models compared here use LiFePO4 (LFP) batteries.
Apps, backup switching and expansion
- Apps: both do remote monitoring and storm prep: EcoFlow’s Storm Guard “automatically activates backup power before extreme weather hits,” and the Apex 300’s Extreme Weather Alert switches to backup when a warning is issued.
- Outage switchover: Elite 100 V2 10ms or less, Elite 200 V2 “within 15ms,” Apex 300 “0ms or 20ms,” per BLUETTI; DELTA 3 and DELTA 3 Max under 10ms, DELTA Pro 3 10ms.
- Expansion: the DELTA 3 grows to 5kWh; neither Elite takes extra batteries. At the top, the Apex 300 reaches 58,060.8Wh with 3 units and 18 B300K batteries (its headline says “2.7kWh to 100kWh”; its FAQ gives the lower figure), the DELTA Pro 3 48kWh.

Price: who gives more for the money?
Per watt-hour of rated battery, BLUETTI is cheaper in the 1kWh class (Elite 100 V2 about 49 cents per Wh vs the DELTA 3’s 57 cents), the 2kWh class is a tie (about 43 cents each), and the Apex 300 costs $1,300 less than the DELTA Pro 3 but holds about 1,330Wh less. Per tested usable Wh: about 56 cents for the Elite 100 V2, 67 for the DELTA 3.
Both stores show crossed-out “was” prices on some models; the DELTA 3’s $699 matches the list price OutdoorGearLab gives. A law firm, Warren Terzian, says it is evaluating a class action over “limited-time” sales against sellers including both brands; we found no case filed. Compare today’s prices, not the discounts. EcoFlow also offers a 30-day price match during promotions, excluding flash sale and members-only prices.
Who should pick BLUETTI
- You want the most battery per dollar: the $499 Elite 100 V2 out-delivered the $579 DELTA 3 in testing.
- You charge mainly from solar and want 1,000W input for less.
- You want a company whose complaints at least get answered, with no recall history.
- You want 240V home backup for about half the DELTA Pro 3’s price (Apex 300), with less starting capacity.
Who should pick EcoFlow
- You need fast wall charging: the DELTA 3’s tested 50-minute refill is the fastest of any model on this page.
- You want to start with 1kWh and add batteries later (DELTA 3, up to 5kWh).
- You want the best-tested whole-home unit and can handle 114 pounds: the DELTA Pro 3.
- You might return it: EcoFlow’s window starts at delivery, its policy doesn’t demand an unused unit, and it pays warranty shipping both ways.

FAQ
Is BLUETTI better than EcoFlow?
For value and customer record, yes: the $499 Elite 100 V2 delivered 890Wh in testing vs 870Wh from the $579 DELTA 3, and BLUETTI left 7 of 37 BBB complaints unanswered vs EcoFlow’s 124 of 127. EcoFlow is better for fast charging, expansion and tested whole-home backup.
Which charges faster, BLUETTI or EcoFlow?
EcoFlow. OutdoorGearLab recharged the DELTA 3 from the wall in about 50 minutes and the BLUETTI Elite 100 V2 in about 2 hours. Popular Science charged the larger Elite 200 V2 in a little over 90 minutes.
Which has the better warranty, BLUETTI or EcoFlow?
Both give 5 years on most current models, but EcoFlow’s DELTA 3 Max needs app registration for years 4 and 5. EcoFlow’s policy says it pays repair shipping both ways in the contiguous US; BLUETTI’s policy doesn’t say who pays.
BLUETTI or EcoFlow for home backup?
The EcoFlow DELTA Pro 3 ($2,799) is better tested: 3,790Wh usable of 4,096Wh and OutdoorGearLab’s home backup pick. The BLUETTI Apex 300 ($1,499) costs much less and holds 2,764.8Wh, but has no independent capacity test.
Can you return a BLUETTI or EcoFlow power station?
Yes, within 30 days, but you pay either way. BLUETTI counts from purchase, requires an unused unit and charges shipping both ways. EcoFlow counts from delivery and charges a 2.6% to 3.6% payment fee plus fixed shipping, such as $29 for a DELTA 3.
Has EcoFlow or BLUETTI had a recall?
EcoFlow recalled about 25,030 DELTA Max 2000 power stations in October 2025 after six fires; the fix is a free firmware update. We found no BLUETTI recall in the CPSC’s recall list through October 22, 2026.
