Notes on the figures

  1. Elite 200 V2, rated capacity: Tech Specs OUTPUT row ‘Capacity’; identical cell in the Compare table’s Elite 200 V2 column. Product copy: ‘With 2,073.6Wh capacity and 2,600W output’.
  2. DELTA 2 Max, rated capacity: Listed under “Capacity” on the manufacturer’s spec sheet for the base unit.
  3. Elite 200 V2, continuous output: Tech Specs row ‘AC Outlets’ reads ‘2,600W in total, 120V,21.6A’; ‘Inverter Type: Pure Sine Wave’.
  4. DELTA 2 Max, continuous output: Total continuous AC output across all six outlets.
  5. Elite 200 V2, surge: This is BLUETTI’s ‘Power Lifting’ mode for pure resistive loads only (Tech Specs row ‘Lifting Power: 3,900W’), not a conventional surge/peak rating; no conventional surge figure is stated. The user manual adds: ‘While the Elite 200 V2 can handle such loads, its actual output power is still 2,600W.’ It is not a conventional motor-start surge rating and should not be read as one.
  6. DELTA 2 Max, surge: Conventional surge rating; the page separately markets a boost mode of 3400 W for resistive loads.
  7. Elite 200 V2, full recharge: Hero stat ‘1.4Hrs Full Charge’ does not label the charging source; the Wall Charging tab lists 1,800 W AC input.
  8. DELTA 2 Max, recharge: The manufacturer does not state a full 0-100% wall-recharge time. It states an 80% charge in 1.1 hours on AC alone, and 80% in 43 minutes when 1800 W AC input is combined with 600 W of solar input.
  9. Elite 200 V2, cell chemistry: Tech Specs BATTERY INFO row ‘Type’. Page copy also says ‘automotive-grade LiFePO₄ battery cells’.
  10. DELTA 2 Max, cell chemistry: Listed under “Battery Chemistry” on the manufacturer’s spec sheet.
  11. Elite 200 V2, cycle life: “6,000+” means at least 6,000 cycles while retaining 80% of original capacity.
  12. Elite 200 V2, cycle life: 6,000+ Cycles to 80% Original Capacity
  13. DELTA 2 Max, cycle life: Rated to the point where at least 80% of original capacity remains.
  14. DELTA 2 Max, cycle life: The manufacturer writes “80+%”, meaning 80 percent or more of the original capacity remains after the rated cycles.
  15. Elite 200 V2, UPS switchover: Upper bound (‘within 15ms’), from page FAQ Q3 ‘Does Elite 200 V2 have a UPS function?’. Overview copy also says ‘0.015s silky smooth switching power supply during a power outage’. Manual Specifications: ‘Switchover Time 15 ms’.
  16. DELTA 2 Max, UPS switchover: Upper bound. The page states the auto-switch to battery power happens in under 20 milliseconds.
  17. Elite 200 V2, expandable: Both the FAQ and the Tech Specs table state the unit is not expandable.
  18. DELTA 2 Max, expandable: Capacity expands by attaching up to two extra batteries.
  19. DELTA 2 Max, expandable: Maximum system capacity with two extra batteries attached.
  20. Elite 200 V2, solar input: Stated as 1,000 W maximum solar input (12-60 V, 20 A).
  21. DELTA 2 Max, solar input: Total across the two solar input ports; a single port accepts up to 500 W.
  22. Elite 200 V2, AC input: The 1,800 W maximum applies in Turbo charging mode (15 A); Standard and Silent modes charge at 1,440 W and 800 W.
  23. DELTA 2 Max, AC input: Maximum AC wall-charging input.
  24. DELTA 2 Max, AC outlets: Six household AC outlets sharing a 2400 W total output.
  25. Elite 200 V2, USB-C: Per port; the unit has two 100 W USB-C (PD 3.0) ports and two 15 W USB-A ports.
  26. DELTA 2 Max, USB-C: Per port; the unit has two USB-C ports.
  27. Elite 200 V2, app: FAQ Q5 ‘Does Elite 200 V2 support remote app control?’. Tech Specs GENERAL row ‘App Control: WiFi / Bluetooth’.
  28. DELTA 2 Max, app: Controlled through the EcoFlow app; the spec sheet lists Wi-Fi and Bluetooth connectivity.
  29. Elite 200 V2, noise: Marketing headline; the accompanying text says ‘Under low power loads’, so 16 dB is a minimum, not a maximum. The user manual Specifications state ‘Noise 16dB to 50dB’ and Silent charging mode ’16dB to 30dB’.
  30. DELTA 2 Max, noise: Measured at a distance of approximately 20 inches, with low charging input and a 500 W output load, per the page’s own footnote.
  31. Elite 200 V2, warranty: Stated as a 5-year warranty in the Tech Specs.
  32. DELTA 2 Max, warranty: The maker markets this as an “Extensive 5-Year Warranty” on the product page.
  33. Elite 200 V2, weight: Tech Specs GENERAL row ‘Weight’ and Compare table Elite 200 V2 column. The user manual lists ‘24.2kg (53.35lbs)’.
  34. DELTA 2 Max, weight: Net weight of the base unit; the same spec sheet lists the metric weight as 23 kg.
  35. Elite 200 V2, price: “priceType”:”https://schema.org/ListPrice”,”price”:”899.00″,”priceCurrency”:”USD”
  36. DELTA 2 Max, price: List price; a sale price of $1,049.00 was shown.

Calculated, not measured: hours = rated Wh × efficiency ÷ (appliance W × duty); assumptions on How we verify. “Unlikely to start”: start-up surge exceeds the stated surge rating.

What the differences mean

Price per watt-hour. At the list prices we checked, the Elite 200 V2 costs $0.43/Wh against $0.63/Wh for the DELTA 2 Max. At list the Elite 200 V2 is $400 cheaper ($899 vs $1,299) for 2,073.6 Wh vs 2,048 Wh. Prices move with sales; the ratio moves with them.

Weight for the capacity. The DELTA 2 Max carries 41.0 Wh/lb against 38.8 Wh/lb for the Elite 200 V2. Both are cart-or-two-people units; the difference matters if the unit moves between car, porch and basement.

Cycle rating. The Elite 200 V2 is rated for 6,000 cycles against 3,000 for the DELTA 2 Max, both to the same remaining-capacity threshold — otherwise we would not compare them. At one full cycle a week the difference is measured in years, not months; at occasional outage use neither limit is reached.

Output for the money. 2.89 W/$ on the Elite 200 V2 against 1.85 W/$ on the DELTA 2 Max: 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 200 V2 leads on cost per watt-hour ($0.43/Wh vs $0.63/Wh), rated cycle life (6,000 vs 3,000) and continuous watts per dollar (2.89 W/$ vs 1.85 W/$). The DELTA 2 Max answers on watt-hours per pound (41.0 Wh/lb vs 38.8 Wh/lb). What decides it is the figure your outage actually tests:

  • CPAP overnight. Switchover: Elite 200 V2 up to 15 ms, DELTA 2 Max under 20 ms. A 40 W CPAP runs roughly 36–43 hr on the Elite 200 V2 and 36–42 hr on the DELTA 2 Max. Both run the night; both switchover figures are upper bounds, so they are too close to call from published numbers.
  • Keeping a refrigerator cold. Start-up comes first. The Elite 200 V2 states a boost figure rather than a motor-start surge rating; the DELTA 2 Max states a 4,800 W surge rating. A full-size refrigerator needs about 900 W to start.
  • A multi-day outage with a generator or solar to recharge from. Full recharge: Elite 200 V2 84 min (charging source not specified), DELTA 2 Max 0–80% in 66 min (no full-charge time stated). These are not comparable: EcoFlow states no full-charge time for the DELTA 2 Max.

A 2,048–2,073.6 Wh battery cannot do what a gasoline generator does — the runtime table shows a 1,500 W space heater emptying either unit in about 1.2 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.
