EcoFlow vs BLUETTI (2026): Which Power Station Gives You More for Your Money?

EcoFlow and BLUETTI both sell LiFePO4 power stations from lunchbox-size units up to whole-home backup systems. Both have been around long enough to build big lineups, both sell direct from their own US stores at a discount off list, and their spec sheets look similar at first glance. So which one gets you more backup power for your money in 2026?

We lined up each brand's current models in four matching size classes: about 1 kWh, 2 kWh, 3 kWh, and 120/240V home backup. For each pair we pulled the price, rated capacity, continuous output, weight, cycle rating, switchover time and warranty from the brands' own stores, and worked out what one kilowatt-hour of battery costs. Every number here was checked on September 24, 2026.

How we compared EcoFlow and BLUETTI

This is a research-based comparison, not a hands-on test. We haven't run these eight units side by side for this article, and we'll update it if we do. What we did do: pulled every price and spec from us.ecoflow.com and bluettipower.com on the same day, matched models by rated capacity, and calculated price per kWh of battery (price ÷ watt-hours × 1,000). We also compared price per watt of continuous output, because capacity alone won't tell you whether a unit can start your well pump or run a space heater.

We compared base units only, with no solar panels or extra batteries, at the sale price each store showed that day. We read both brands' return policies too. Where a spec wasn't published, we say so rather than guess.

Price vs price: every size class compared

Sale prices from us.ecoflow.com and bluettipower.com, September 24, 2026, base unit only (no solar panels or add-on batteries). Wh = rated battery capacity; W = continuous AC output. $ per kWh = price ÷ capacity × 1,000. Prices change often.

BLUETTI is about 27% cheaper per kWh at 1 kWh, 11% cheaper at 3 kWh and 21% cheaper for home backup. At 2 kWh the two are within about 1%. But price per kWh isn't the whole story. At 3 kWh and home backup, the EcoFlow units deliver more continuous power, so per watt of output EcoFlow is the better deal in both of those classes.

Head-to-head, size by size

1 kWh: DELTA 3 Plus vs Elite 100 V2

EcoFlow DELTA 3 Plus: 1,024Wh · 1,800W continuous · 27.6 lb · 120V · 4,000 to 80% cycle rating · UPS <10 ms

BLUETTI Elite 100 V2: 1,024Wh · 1,800W continuous · 25 lb · 120V · 4,000+ to 80% cycle rating · UPS <=10 ms

On paper these are twins: 1,024Wh, 1,800W continuous, LiFePO4 cells rated around 4,000 cycles to 80%, and 10 ms-class UPS switchover. The difference is price. The BLUETTI Elite 100 V2 costs $180 less, which works out to $478/kWh vs $653/kWh. It's also a bit lighter at 25 lb vs 27.6 lb, and BLUETTI quotes 0 to 80% in 45 minutes on AC.

The EcoFlow DELTA 3 Plus has a few extras for the money: 13 outputs, an IP65-rated battery pack, and expansion up to 5 kWh with EcoFlow extra batteries. It was a pre-order shipping in November when we checked, while the Elite 100 V2 was available to order. For most buyers who just want a 1 kWh backup, the BLUETTI is the better value.

2 kWh: DELTA 3 Max vs Elite 200 V2

EcoFlow DELTA 3 Max: 2,048Wh · 2,400W continuous · 44.8 lb · 120V · not listed (EcoFlow says 10 years) cycle rating · UPS <10 ms

BLUETTI Elite 200 V2: 2,073.6Wh · 2,600W continuous · 53.4 lb · 120V · 6,000+ to 80% cycle rating · UPS not listed

The closest race in this comparison. The EcoFlow DELTA 3 Max is $20 cheaper ($429/kWh vs $434/kWh) and 8.6 lb lighter at 44.8 lb. The BLUETTI Elite 200 V2 holds a little more (2,073.6Wh), puts out more (2,600W vs 2,400W), takes twice the solar input (1,000W vs 500W), and carries a 6,000-cycle rating. EcoFlow doesn't publish a cycle figure for the DELTA 3 Max; it says the cells are built for 10 years.

Per watt of output, the BLUETTI is slightly cheaper: $0.35 vs $0.37. If you'll carry it to camp, take the lighter EcoFlow. If it will mostly sit at home on solar, the BLUETTI's extra output and solar input make more sense.

3 kWh: DELTA 3 Ultra vs Elite 300

EcoFlow DELTA 3 Ultra: 3,072Wh · 3,600W continuous · 72.1 lb · 120V (30A outlet) · not listed (EcoFlow says 10 years) cycle rating · UPS <10 ms

BLUETTI Elite 300: 3,014.4Wh · 2,400W continuous · 57.98 lb · 120V (TT-30 outlet) · 6,000+ to 80% cycle rating · UPS <=10 ms

Here the two brands built very different machines. The BLUETTI Elite 300 is the value play: $1,199, 3,014Wh, 58 lb, a 6,000-cycle rating and a 12V/30A RV port, for $398/kWh. The EcoFlow DELTA 3 Ultra costs $170 more but puts out 3,600W continuous (7,200W surge) vs 2,400W (4,800W surge).

That output gap matters in an outage. 2,400W runs a fridge, freezer, lights and a microwave, but not much at the same time as a big space heater or a well pump. Per watt, the EcoFlow is cheaper at $0.38 vs $0.50. It also expands to 11 kWh with two DELTA Pro 3 extra batteries. The trade-off is weight: 72.1 lb vs 58 lb.

Home backup: DELTA Pro 3 vs Apex 300

EcoFlow DELTA Pro 3: 4,096Wh · 4,000W continuous · 113.5 lb · 120/240V · 4,000 to 80% cycle rating · UPS 10 ms

BLUETTI Apex 300: 2,764.8Wh · 3,840W continuous · 83.78 lb · 120/240V (NEMA 14-50) · 6,000+ to 80% cycle rating · UPS 0 ms (per BLUETTI)

Both put out 120V and 240V, so either can feed home circuits through a transfer switch. The BLUETTI Apex 300 is much cheaper to get into: $1,499 for 2,764.8Wh and 3,840W, vs $2,799 for the DELTA Pro 3's 4,096Wh and 4,000W. That's $542/kWh vs $683/kWh. The Apex also weighs 30 lb less (83.8 lb vs 113.5 lb), has a 6,000-cycle rating, and BLUETTI lists 0 ms UPS switchover.

Add capacity and the gap stays wide. BLUETTI's Apex 300 + B300K bundle was $2,599 for 5,529.6Wh, less than a single DELTA Pro 3. BLUETTI says an Apex system scales from 2.7 to 100 kWh and 3.8 to 11.5 kW. The DELTA Pro 3's edge is the bigger single unit: 4 kWh and 4,000W in one box on wheels, expandable to 12 kWh per unit and 48 kWh in a system, with EcoFlow listing it as UL 9540 certified. It was shipping in late September when we checked.

What about whole-home backup?

Above these units, both brands sell bigger systems. EcoFlow's DELTA Pro Ultra is $4,199 for 6,144Wh and 7,200W at 120/240V, and the newer DELTA Pro Ultra X starts at $7,999 for about 12 kWh and 12 kW. BLUETTI's long-running AC500 + B300S kits were listed from $2,299 (5,000W, 3,072Wh), but every AC500 bundle showed sold out on BLUETTI's US store when we checked, which is why we used the Apex 300 above.

We've covered these in depth: read our EcoFlow DELTA Pro Ultra X review, our EcoFlow DELTA Pro Ultra whole-home backup guide, and our BLUETTI AC500 + 3× B300S review. If you already own an older DELTA Pro, see our DELTA Pro extra battery review.

Everything else, side by side

A note on cycle ratings: BLUETTI's 6,000-cycle figures are higher than anything EcoFlow publishes for these models. Both are the makers' own lab numbers. At one full cycle a day, 4,000 cycles is about 11 years, so most backup-only owners won't wear out either brand.

Where BLUETTI wins

• More battery per dollar at 1 kWh, 3 kWh and home backup.
• A cheap way into 240V: the Apex 300 is $1,300 less than a DELTA Pro 3.
• Higher cycle ratings: 6,000+ to 80% on the Elite 200 V2, Elite 300 and Apex 300.
• Lighter at 1 kWh, 3 kWh and home backup.

Where EcoFlow wins

• More power at 3 kWh: 3,600W vs 2,400W, and cheaper per watt.
• More in one box: the DELTA Pro 3 packs 4 kWh and 4,000W at 120/240V.
• The lighter 2 kWh unit, and slightly cheaper per kWh there.
• Expandable smaller units (DELTA 3 Plus to 5 kWh, DELTA 3 Ultra to 11 kWh).

Which should you buy?

For a 1 kWh backup or camp battery: the BLUETTI Elite 100 V2. Same capacity and output as the DELTA 3 Plus for $180 less.

For about 2 kWh: the EcoFlow DELTA 3 Max if you'll carry it, the BLUETTI Elite 200 V2 if it stays home on solar.

For about 3 kWh: the BLUETTI Elite 300 if you're storing energy for a fridge, lights and devices. The EcoFlow DELTA 3 Ultra if you need to run bigger loads at once.

For 240V home backup on a budget: the BLUETTI Apex 300, and add a B300K when you can. Pick the EcoFlow DELTA Pro 3 if you want 4 kWh and 4,000W in a single rolling unit. Either way, have a licensed electrician install the transfer switch.
