Same battery, same 1,800W, same 10ms UPS. One drinks twice the sun; the other grows.
The BLUETTI Elite 100 V2 and the EcoFlow DELTA 3 both store 1,024Wh of LFP rated for 4,000 cycles, deliver 1,800W and switch to battery in 10ms. The Elite 100 V2 takes 1,000W of solar instead of 500W and is about 15% smaller, at 25.3 lb, but has four AC outlets and can’t be expanded. The DELTA 3 has six outlets, an IP65 battery pack and grows to about 5kWh with extra batteries, at 27.6 lb, and refills from the wall in 56 minutes.
Below: every difference with numbers, a 20-second calculator for your own gear, eight modeled situations, a third option, and what published tests found on each.
Same 1,024Wh, 1,800W, 10ms UPS and 4,000 cycles. The DELTA 3 costs $80 more today for two more outlets, an IP65 pack, a faster default wall refill and room to grow to about 5kWh; the Elite 100 V2 takes twice the solar in a smaller box.

The five differences that decide it
The five gaps that decide the purchase, with the better spec for most buyers flagged. Both store 1,024Wh of LFP rated for 4,000 cycles, deliver 1,800W, switch to battery in 10ms, have a 12V car socket and two DC5521 barrels, and carry a 5-year warranty.
Will it run your setup? Check in 20 seconds
Estimates use 85% usable capacity and 70% of rated solar output. Real results vary with temperature, inverter load, shade and appliance cycling. Fridge and freezer watts are daily averages and do not include compressor startup surges.
Runtime by appliance, one at a time
Simple energy estimates, not measured runtimes. About 870Wh usable on both; OutdoorGearLab measured 890Wh out of the Elite 100 V2 and 870Wh out of the DELTA 3.
Same battery, same runtime.
The Elite 100 V2 and the DELTA 3 both hold about 870Wh usable, so every appliance runs just as long on either one.Get our Black Friday alerts for power stations

The price gap, in numbers
Same 1,024Wh battery: the BLUETTI Elite 100 V2 costs $80 less than the EcoFlow DELTA 3.
Prices refresh daily from BLUETTI US and EcoFlow US.Same capacity and the same 4,000-cycle rating to 80%, so the price gap is the main money question; only the DELTA 3 has a route to 2kWh and beyond. The Elite 100 V2 ships without solar or car cables. Both prices move often; the figures are refreshed daily by our price engine.
The third option: the Anker C1000 Gen 2 at $529.99
Anker SOLIX C1000 Gen 2: $529.99 today
The same 1,024Wh and 10ms UPS with more output than either: 2,000W from five outlets, a 49-minute wall refill and 600W of solar, at 24.9 lb. It can’t be expanded. Pick it if you run kitchen appliances. Our C1000 Gen 2 review goes deeper. See the C1000 Gen 2 at Anker.
Eight modeled situations, worked out
Same formula as the calculator above, with no extra battery. The fridge averages 60W, about 525kWh a year.
24-hour outage, essentials only
Identical: an evening and a night each. Only the DELTA 3 can add a battery for a second day.
CPAP, two nights
Both cover two nights and both switch in 10ms. BLUETTI and EcoFlow both rate their unit around 30dB at moderate loads.
Six plugs at once
The DELTA 3 takes all six plugs; on the Elite 100 V2, add a power strip, keeping the total under 1,800W.
Refill from solar, 800W of panels
With 500W of panels or less they refill at the same pace. Above that, only the Elite 100 V2 uses the extra panels.
Refill from the wall before a storm
Both are quick in their fastest mode; by default, the Elite 100 V2 charges at 600W and takes about 2 hours.
Home office through an outage
Identical, and both switch in 10ms, inside what desktop power supplies ride through.
Growing the system
Only the DELTA 3 grows.
Carrying it
Both are one-hand carries; the Elite 100 V2 is 2.3 lb lighter and smaller.

09 · NoiseNoise: Elite 100 V2 vs DELTA 3
A near tie on paper: BLUETTI rates the BLUETTI Elite 100 V2 at 30dB under 600W, EcoFlow the EcoFlow DELTA 3 under 30dB at 600W. Reviewers found the Elite 100 V2 remarkably quiet.
These are brand figures; we found no independent dB measurement for either model.Every figure we found, with its source
What reviewers heard: Never louder than a whisper (Popular Science); the fan stayed very quiet at 80% of rated output (OutdoorGearLab); not loud or intrusive at 1,800W from full to empty (Trusted Reviews, UK unit).

Cold and heat: Elite 100 V2 vs DELTA 3
For a cold garage, the BLUETTI Elite 100 V2 keeps running down to −4°F; for heat and wet, the EcoFlow DELTA 3 is rated to 113°F and its battery pack is IP65. Neither charges below freezing.
Figures from the Elite 100 V2 user manual and EcoFlow US.- Charge either one indoors in winter: neither charges below 32°F.
App, UPS and smart features
The EcoFlow DELTA 3 does more: it takes extra batteries, prepares for storms and can start a generator on its own. The BLUETTI Elite 100 V2 matches it on UPS speed and pushes heaters further.
Same 10ms UPS, both apps over Wi-Fi and Bluetooth.Green zone: a switch under about 16ms, which most desktop PCs ride through without restarting.
Can you add a battery later? The EcoFlow DELTA 3 takes DELTA 3, DELTA 2, DELTA 2 Max or DELTA Pro 3 extra batteries, up to about 5kWh; the BLUETTI Elite 100 V2 stops at 1,024Wh.
Does it prepare for storms? The EcoFlow DELTA 3 has a Storm Warning Alert in the app; BLUETTI lists no such feature for the Elite 100 V2.
Can it start a generator by itself? The EcoFlow DELTA 3 can start and stop EcoFlow’s Smart Generator 3000 on its own; BLUETTI lists no such feature for the Elite 100 V2.
Does it work as a UPS? Both switch to battery in 10ms, inside the roughly 16ms ATX desktop power supplies ride through at full load.
Can it charge off-peak? Both can schedule charging: Time Control and custom schedules with charge limits on the BLUETTI Elite 100 V2, time-of-use settings on the EcoFlow DELTA 3.
Can it run a heater or kettle above its rating? Both run heaters past the rating at reduced power, not motors: up to 2,700W on the BLUETTI Elite 100 V2, 2,200W on the EcoFlow DELTA 3.
How does the app connect? Both use their brand’s app over Wi-Fi or Bluetooth. On the BLUETTI Elite 100 V2, turn ECO mode off for fridges, CPAP machines and routers.
Warranty and support
Same 5 years on both. EcoFlow lists no registration condition for the EcoFlow DELTA 3; BLUETTI covers the BLUETTI Elite 100 V2 from purchase, with proof of purchase.
BLUETTI voids the Elite 100 V2’s warranty if you buy from an unauthorized reseller.Subject to each brand’s warranty terms and eligibility.
Both are rated for 4,000 cycles to 80%, about 11 years at one full cycle a day. Heat and age also wear a battery, so read the rating as a ceiling.
- Buy the Elite 100 V2 from BLUETTI or an authorized seller and keep the receipt: BLUETTI voids the warranty for unauthorized resellers and limits it to the country of purchase.
- The DELTA 3 needs no registration to get its full 5 years.
What reviewers report
We have not lab-tested these two units. Here is what 7 published reviews found, with the source, author and date for each point. Reviews of UK and EU units are flagged: those models charge from 230V outlets and have different sockets, so their charge times and outlet findings don’t carry over to US units.
