Notes on the figures

  1. Elite 100 V2, rated capacity: Tech Specs > OUTPUT > Capacity; the hero banner also states ‘1,024Wh Capacity’.
  2. DELTA 3 Plus, rated capacity: 1024Wh
  3. Elite 100 V2, continuous output: Tech Specs > OUTPUT > Output Power. FAQ A4 also states ‘The Elite 100 V2 provides 1,800W continuous AC output’.
  4. DELTA 3 Plus, continuous output: 1800W
  5. Elite 100 V2, surge: Conventional surge rating: Tech Specs > OUTPUT > ‘Surge Power’ = ‘3,600W’. The page separately lists ‘Lifting Power’ = ‘2,700W’ (BLUETTI’s boost mode for resistive loads); the product bullets say ‘1,800W output (2,700W Lifting Power)’.
  6. DELTA 3 Plus, surge: EcoFlow’s X-Boost raises sustained output to 2,200 W for resistive loads; 3,600 W is the surge figure. The two are different things.
  7. Elite 100 V2, full recharge: Tech Specs > INPUT > AC Charging Time (wall, with 1,200W AC TurboBoost). FAQ A3: ‘it charges from 0–80% in just 45 minutes, and reaches 100% in about 70 minutes.’ Full 0-100% = 70 min; 0-80% = 45 min.
  8. DELTA 3 Plus, full recharge: With the 1,500 W AC input setting.
  9. Elite 100 V2, cell chemistry: Tech Specs > BATTERY INFO > Type. FAQ A7: ‘It uses ultra-safe LiFePO₄ (LFP) batteries’.
  10. DELTA 3 Plus, cell chemistry: Third-gen LiFePO4 (LFP) cells offer fast charging without sacrificing longevity.
  11. Elite 100 V2, cycle life: Tech Specs > BATTERY INFO > Cycle Life. The ‘+’ means 4,000 is a floor (“over 4,000 cycles” in bullets).
  12. Elite 100 V2, cycle life: 4,000+ Cycles to 80% Original Capacity
  13. DELTA 3 Plus, cycle life: With 4000 cycles to 80% capacity, enjoy up to 10 years of reliable use, 25% above the industry standard.
  14. Elite 100 V2, UPS switchover: Upper bound: Tech Specs > GENERAL > UPS Switching Time is ‘≤10 ms’. Bullets/FAQ A8 phrase it as ’10ms switching time’.
  15. DELTA 3 Plus, UPS switchover: Stated as under 10 ms; an upper bound.
  16. Elite 100 V2, expandable: A B80 battery can charge it through the DC input in Power Bank Mode (FAQ A18); capacity is not extended as a single system, the rule we apply to every unit that can only be charged by an external battery.
  17. DELTA 3 Plus, expandable: up to 5kWh expandable
  18. Elite 100 V2, solar input: Tech Specs > INPUT > Solar Input. FAQ A5: ‘Total VOC: 12V–60V’, ‘Total Power: 1,000W Max’.
  19. DELTA 3 Plus, solar input: 2 ports, DC Charge Input, 11V-60V 500W Max*2
  20. Elite 100 V2, AC input: Tech Specs > INPUT > AC Input (charging). A separate line ‘AC Input (Charging + Bypass)’ = ‘1,800W Max.’ covers pass-through/bypass load.
  21. DELTA 3 Plus, AC input: 1500W
  22. DELTA 3 Plus, AC outlets: 6 outlets, 1800W total (Surge 3600W)
  23. Elite 100 V2, USB-C: Tech Specs > OUTPUT > USB-C Port: two USB-C ports, one 100W max and one 140W max.
  24. DELTA 3 Plus, USB-C: 2 ports, 140W Max
  25. Elite 100 V2, app: Tech Specs > GENERAL > Connectivity = ‘WiFi / Bluetooth’. BLUETTI App supports charging-mode selection and Power Memory Mode (FAQ A10).
  26. DELTA 3 Plus, app: APP (TOU / Storm Warning Alert)
  27. Elite 100 V2, noise: Condition: under 600W load. Tech Specs > GENERAL > Noise = ’30 dB’.
  28. DELTA 3 Plus, noise: Stated as under 30 dB at 600 W output and under 40 dB at 1,200 W; an upper bound at a stated load.
  29. Elite 100 V2, warranty: Tech Specs > GENERAL > Warranty. FAQ A7: ‘it comes with a 5-year warranty’.
  30. DELTA 3 Plus, warranty: 5 years
  31. Elite 100 V2, weight: Tech Specs > GENERAL > Weight. FAQ A2 gives a slightly different figure: ‘It weighs just 25.3lbs(11.5kg )’.
  32. DELTA 3 Plus, weight: Manufacturer states ‘approx.’
  33. Elite 100 V2, price: List price. Bundles range up to $2,199.00.
  34. DELTA 3 Plus, price: Manufacturer list price when checked; on sale at $669 that day.

What the differences mean

Price per watt-hour. At the list prices we checked, the Elite 100 V2 costs $0.49/Wh against $0.78/Wh for the DELTA 3 Plus. At list the Elite 100 V2 is $300 cheaper ($499 vs $799) for 1,024 Wh vs 1,024 Wh. Prices move with sales; the ratio moves with them.

Weight for the capacity. The Elite 100 V2 carries 41.0 Wh/lb against 37.1 Wh/lb for the DELTA 3 Plus. Both are two-hands-and-a-flat-surface units; the difference matters if the unit moves between car, porch and basement.

Recharge. Both store the same 1,024 Wh; the DELTA 3 Plus refills that capacity in less time (56 min vs 70 min).

Output for the money. 3.61 W/$ on the Elite 100 V2 against 2.25 W/$ on the DELTA 3 Plus: if what you need is to run a high-draw appliance rather than to run a small one for days, this ratio is the one to read.

Which one, and for whom

On normalized measures the Elite 100 V2 leads on cost per watt-hour ($0.49/Wh vs $0.78/Wh), watt-hours per pound (41.0 Wh/lb vs 37.1 Wh/lb) and continuous watts per dollar (3.61 W/$ vs 2.25 W/$). The DELTA 3 Plus answers on recharge rate (18.3 Wh/min vs 14.6 Wh/min). What decides it is the figure your outage actually tests:

  • CPAP overnight. Switchover: Elite 100 V2 up to 10 ms, DELTA 3 Plus under 10 ms. A 40 W CPAP runs roughly 18–21 hr on the Elite 100 V2 and 18–21 hr on the DELTA 3 Plus. Both makers state a 10 ms upper bound, so for one night’s CPAP the deciding figures are price and solar input.
  • Keeping a refrigerator cold. Start-up comes first. Both state a 3,600 W surge and both calculate to 16–17 hr on a full-size refrigerator, so this scenario does not separate them.
  • A multi-day outage with a generator or solar to recharge from. Full recharge: Elite 100 V2 70 min, DELTA 3 Plus 56 min. The faster unit spends less generator fuel per charge.

A 1,024 Wh battery cannot do what a gasoline generator does — the runtime table shows a 1,500 W space heater emptying either unit in about 0.6 hr — but it also cannot poison a household. Our CPSC revision matrix tracks how the official count of generator carbon-monoxide deaths has changed across report editions, and this page puts every verified unit on the same refrigerator scenario.
