Bluetti vs EcoFlow

How this page makes money. Some links on this page are affiliate links: if you buy through them we may earn a commission (on this page: BLUETTI). Brands that pay us nothing are included wherever leaving them out would make a comparison less useful.

The one question that decides it

How often will you recharge it?

That is how the two brands are usually told apart, though on charging the gap is smaller than the marketing suggests. Bluetti builds for capacity: more stored energy per dollar and expandable systems. EcoFlow markets fast charging and software, at a higher cost per watt-hour, but matched models from the two brands refill from the wall at similar speeds (figures below).

If the unit will sit charged in a cupboard waiting for an outage, capacity per dollar matters most, and that favors Bluetti. If it is in constant rotation — camping most weekends, van life, job sites — charging speed matters more, so compare the exact models’ AC and solar input figures rather than assuming EcoFlow is faster.

Head to head

Model for model

Matched pairs, on the published numbers

The closest current model from each brand at about 1kWh and about 2kWh, and a 120/240V home-backup unit from each, from the makers’ US product pages on October 12, 2026. Where a sale was running, the regular price is in parentheses.

About 1kWh: AC180 against DELTA 3 Plus

The AC180 stores 12.5% more for $220 less at these prices. The DELTA 3 Plus has twice the solar input, a 4,000-cycle rating against 3,500+ and 7.7 lb less weight, and it takes extra batteries (EcoFlow lists 1–5kWh). BLUETTI says the AC180 does not support capacity expansion, though its B80, B230 and B300 batteries can recharge it in Power Bank Mode. EcoFlow’s DELTA 3 Classic stores the same 1,024Wh for $499 ($599 regular; maker list price, October 2026), or $0.49 per Wh.

About 2kWh: Elite 200 V2 against DELTA 3 Max

The two are level on price per Wh only while EcoFlow’s sale runs; at its regular price the DELTA 3 Max works out to $0.59. The Elite 200 V2 has more output, twice the solar input and a 6,000-cycle rating, where EcoFlow gives no cycle figure for the DELTA 3 Max, only an estimated lifespan of about 10 years from its own simulation testing. The DELTA 3 Max is 8.6 lb lighter. BLUETTI says the Elite 200 V2 is not expandable.

Home backup at 120/240V: Apex 300 against DELTA Pro 3

The DELTA Pro 3 holds 48% more in one box. Per Wh, the Apex 300 is cheaper at both sale and regular prices ($0.61 against $0.81 regular). EcoFlow’s 4,000W charging figure needs its EV X-Stream Adapter and a 240V EV charger. Add-on batteries take one Apex 300 to 19,353.6Wh and one DELTA Pro 3 to 12kWh.

Cost per watt-hour

Neither brand puts this figure in its spec tables, and it is the one that makes comparison honest. Divide the price by the capacity and you get what you are actually paying for stored energy. Done for the three pairs above, at each maker’s store price on October 12, 2026:

• About 1kWh: AC180 $0.43 against DELTA 3 Plus $0.70 ($0.78 at its regular price). Bluetti is cheaper.
• About 2kWh: Elite 200 V2 $0.43 against DELTA 3 Max $0.43 on sale, $0.59 at its regular price. A tie only while the sale lasts.
• Home backup: Apex 300 $0.58 ($0.61 regular) against DELTA Pro 3 $0.68 ($0.81 regular). Bluetti is cheaper.

So Bluetti is cheaper per Wh in two of the three pairs and level in the third, but a sale moves these numbers more than the brand does. Recompute on the day you buy; the Power Station Price Index runs the same calculation across 91 power stations.

So which should you buy?

• Backing up a house? The Bluetti Apex 300 for the lower price per Wh, the higher cycle rating and 120V and 240V outlets live at the same time; the EcoFlow DELTA Pro 3 for 4kWh in one box and EcoFlow’s Smart Home Panel 2. Charging speed hardly matters for a unit that sits full.
• Camping or van life? A smaller unit such as the EcoFlow DELTA 3 Classic suits it. You will recharge constantly, so check the exact model’s AC and solar input, because on matched models neither brand is much faster.
• Genuinely unsure? A 2kWh unit covers outages and trips. The Bluetti AC200L is now listed as discontinued on BLUETTI’s US store (checked October 2026); the current 2kWh pair is the Bluetti Elite 200 V2Check price at BLUETTI↗ and the EcoFlow DELTA 3 Max, compared above.

Charging compared properly

On wall charging the two brands are closer than their reputations suggest. Bluetti lists 1,440W of AC input for the AC180 (1,152Wh), up to 2,400W for the AC200L (2,048Wh) and 1,800W for the Elite 200 V2 (2,074Wh). EcoFlow lists 1,400W for the DELTA 3 Classic (1,024Wh), which charges through its X-Stream fast-charging system. The AC180 and the DELTA 3 Classic, the closest pair by capacity, take almost the same wattage from the wall.

So charging speed is a reason to pick a particular model, not a brand: check the AC and solar input of the exact unit you are considering.

Expandability

Both brands sell add-on batteries for many of their models. Bluetti’s include the Apex 300Check price at BLUETTI↗, which takes up to six add-on batteries (the AC200L took them too, but BLUETTI’s US store now lists it as discontinued); EcoFlow’s include the RIVER 3 Plus, DELTA 3 Plus and DELTA Pro 3. If you expect your needs to grow — and for home backup they usually do — check that the exact model you buy takes an expansion battery, because smaller units in both ranges often do not. BLUETTI says neither the AC180 nor the Elite 200 V2 supports capacity expansion.

Wiring either one into a house

• Bluetti Apex 300. One unit has four 20A outlets, a TT-30R RV outlet and a 120/240V NEMA 14-50R, 3,840W in total, and BLUETTI says it powers 120V and 240V devices at the same time, even while charging. It connects to a home through a transfer switch or BLUETTI’s AT1 panel (Apex 300 page checked October 2026).
• EcoFlow DELTA Pro 3. EcoFlow’s FAQ says it cannot output 120V and 240V at the same time from its separate outlets. The 240V button powers the L14-30 split-phase and 6-20R outlets and switches off the 120V outlets; the 120V button does the reverse. So a 240V well pump on the 6-20R and a fridge on a 120V outlet cannot run together. The L14-30 is split-phase, though, and EcoFlow says it powers 120V and 240V home appliances through an inlet box. EcoFlow lists Smart Home Panel 2, an inlet box or a manual transfer switch for connecting the unit to a house, and notes that Smart Home Panel 2 must be installed before use. Its store lists DELTA Pro 3 bundles with the panel and with a transfer switch, all sold out on October 12, 2026 (DELTA Pro 3 page and FAQ).

What a transfer switch involves is covered in Manual Transfer Switch; sizing a battery to a whole house, in Home Battery Backup.

Warranty, as published

All six models in the matched pairs carry 5 years on their makers’ US product pages. EcoFlow’s pages for the DELTA 3 Max, DELTA 3 Classic and DELTA Pro 3 describe that as a 3-year standard warranty plus 2 years added when you register the unit in the EcoFlow app (DELTA 3 Max page checked October 2026), so register an EcoFlow unit when you set it up. BLUETTI’s spec tables list 5 years for the AC180, Elite 200 V2 and Apex 300.

What about the other brands?

This comparison gets the most attention, but the two-horse framing is incomplete:

• Anker SOLIX sits between them on price with strong build quality.
• Jackery is the easiest to live with. Camping rather than backup.
• OUPES undercuts both on watt-hours per dollar if you can live with a less established name.
• Mango Power leads with home backup rather than portability.
• ALLPOWERS is the budget option that still uses LiFePO4 cells.
