Bluetti Elite 100 V2 vs EcoFlow DELTA 3 (2026): which should you buy?
By Mike · Updated October 8, 2026 · Based on manufacturer specs and the Amazon listings
Same capacity, same 1,800W. The split is simple: the DELTA 3 can add batteries and refills faster from the wall, and the Elite 100 V2 is lighter, takes up to twice the solar (1,000W in Turbo mode, 600W otherwise) and is rated for colder weather.
Choose the Bluetti Elite 100 V2 if
- You recharge from solar. It takes up to 1,000W in Turbo mode. The DELTA 3 takes 500W.
- You'll carry it. It's about 25.3 pounds, 2.3 pounds lighter.
- It will sit somewhere cold. Bluetti rates discharge down to -4°F. EcoFlow's manual says 14°F.
- You want a published standby draw to plan runtime around. Bluetti lists about 10W. EcoFlow lists none for the DELTA 3, so ours is an assumed range.
Choose the EcoFlow DELTA 3 if
- You might want more capacity later. It takes EcoFlow extra batteries up to 5kWh. The Elite 100 V2 has no expansion port.
- You want the fastest wall charge: EcoFlow lists 56 minutes to full at 1,500W. Bluetti lists 80% in 45 minutes in Turbo mode at 1,200W.
- You plug in a lot at once: 6 AC outlets against 4.
The two units
Bluetti Elite 100 V2
1,024Wh and 1,800W in about 25 pounds. Bluetti publishes a low standby draw (about 10W), and it has no expansion port.
EcoFlow DELTA 3
1,024Wh and 1,800W in about 27.6 pounds. It's the only 1kWh unit here that takes an add-on battery, up to 5kWh.

Where the sources disagree:
- Bluetti Elite 100 V2: Surge: the Amazon listing's detail fields say "3600W Surge Power". Bluetti's page and manual only give 2,700W Power Lifting Mode, for resistive loads rated 1,800 to 2,700W, and say actual output stays 1,800W. The page doesn't use 3,600W.
- Bluetti Elite 100 V2: Noise: the product page says 30dB under 600W. The manual's spec table says 50dB max.
- Bluetti Elite 100 V2: Weight: the manual says 25.3 lb; the product page and Amazon listing say 25 lb.
- Bluetti Elite 100 V2: Solar: the 1,000W solar figure is for Turbo mode. In Standard and Silent mode the manual caps solar at 600W.
- EcoFlow DELTA 3: X-Boost: EcoFlow's spec table says "Max Device(s) Power (with X-Boost) 2200W". The page copy, manual (120V) and Amazon listing say over 2,600W. The page shows both.
- EcoFlow DELTA 3: Charge time: EcoFlow's page says 56 min to full on 1,500W AC alone. The Amazon listing ties the 56 min to "500W solar input and 1500W max AC input" combined. The page uses EcoFlow's page.
Specs are from Bluetti's product page and user manual, EcoFlow's product page and user manual, and the two Amazon listings, checked October 8, 2026.
What they will run (estimates)
Hours = capacity x 0.85 x 0.90 ÷ (load + standby draw). The 0.85 covers inverter losses. The 0.90 assumes 90% of the battery is usable. That's the figure Bluetti publishes, and we apply it to every unit because the other makers publish none. Standby draw is each maker's own figure. These are estimates, not tests. Where a maker publishes no standby draw, we show a range (see the note under the table).
| Load (typical draw) | Elite 100 V2, 1,024Wh | DELTA 3, 1,024Wh |
|---|---|---|
| Phone charges (about 15Wh each, via USB) | About 52 charges | About 52 charges |
| Wi-Fi router (15W) | About 31 hr | About 24 to 33 hr* |
| CPAP, no heated humidifier (40W) | About 16 hr | About 14 to 16 hr* |
| Mini fridge (45W average), rough estimate | About 14 hr | About 12 to 15 hr* |
| Laptop (60W) | About 11 hr | About 10 to 11 hr* |
| 50-inch TV (100W) | About 7.1 hr | About 6.6 to 7.2 hr* |
| Full-size fridge (120W average), rough estimate | About 6.0 hr | About 5.7 to 6.1 hr* |
| Microwave (1,000W) | About 0.8 hr | About 0.8 hr* |
| Space heater (1,500W) | About 0.5 hr | About 0.5 hr* |
The fridge rows are rough because compressors cycle on and off and pull a surge at startup. The phone row runs off the USB ports, so standby draw doesn't apply.
* EcoFlow doesn't publish a standby draw for the DELTA 3, so its figures assume 9 to 18W. That spans the lowest (Anker C2000 Gen 2, 9W) to the highest (Jackery, 18W) standby draw published by the makers we cover. It's our assumption, not EcoFlow's number.
One night of outage: a full-size fridge plus a CPAP draws about 160W together. The Bluetti Elite 100 V2 runs that pair for about 4.6 hours, and the EcoFlow DELTA 3 about 4.4 to 4.6 hours on an assumed 9 to 18W standby draw. Neither gets through an 8-hour night, so you'd be choosing between the fridge and the CPAP before morning.
Skip it if
Skip the Elite 100 V2 if you'll ever want more than 1,024Wh. It can't add a battery.
Skip the DELTA 3 if solar is your main way to recharge, or you want a published standby draw to plan runtime around.
Questions about this pair
Which one runs longer?
Capacity is identical (1,024Wh). EcoFlow doesn't publish a standby draw for the DELTA 3, so we assume 9 to 18W. On that assumption, a fridge and CPAP (about 160W together) would run about 4.4 to 4.6 hours on the DELTA 3 against about 4.6 on the Elite 100 V2. On those numbers it's too close to call.
Which charges faster?
From the wall, the DELTA 3 on paper: 56 minutes to full at 1,500W. The Elite 100 V2 lists 80% in 45 minutes in Turbo mode and about 2 hours to full in its default Standard mode. Both are makers' figures.
Which is better as a UPS?
Both list a switchover of about 10ms (Bluetti 10ms or less, EcoFlow under 10ms). EcoFlow calls the DELTA 3 a standby UPS. Neither is a zero-break UPS.
What are Power Lifting and X-Boost?
Both let the unit run heating devices above 1,800W by lowering the voltage. Bluetti's goes to 2,700W. EcoFlow lists 2,200W or 2,600W depending on which of its pages you read. Neither helps with motors.
