Anker SOLIX C1000 vs Bluetti Elite 100 V2: cheaper per watt-hour vs lighter per watt-hour

Specifications checked against manufacturer pages on 2026-08-23.

The Anker SOLIX C1000 (1,056 Wh, 1,800 W) and the Bluetti Elite 100 V2 (1,024 Wh, 1,800 W), compared on the figures their makers publish. On the normalized ratios, the C1000 costs less per watt-hour ($0.43/Wh vs $0.49/Wh); the Elite 100 V2 carries more per pound (41.0 Wh/lb vs 37.1 Wh/lb).

In short. The C1000 leads on cost per watt-hour ($0.43/Wh vs $0.49/Wh) and continuous watts per dollar (4.00 W/$ vs 3.61 W/$); the Elite 100 V2 leads on watt-hours per pound (41.0 Wh/lb vs 37.1 Wh/lb) and rated cycle life (4,000 vs 3,000). 2 of 6 measures tie or are not comparable. Pick by the one your outage will test.

Notes on the figures

  1. C1000, rated capacity: 1056Wh
  2. Elite 100 V2, rated capacity: Tech Specs > OUTPUT > Capacity; the hero banner also states ‘1,024Wh Capacity’.
  3. C1000, continuous output: 1800W Pure Sine Wave
  4. Elite 100 V2, continuous output: Tech Specs > OUTPUT > Output Power. FAQ A4 also states ‘The Elite 100 V2 provides 1,800W continuous AC output’.
  5. C1000, surge: Anker labels 2,400 W as ‘SurgePad’, a mode that raises output for resistive loads such as heaters. It is not a conventional motor-start surge rating and should not be read as one.
  6. 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)’.
  7. C1000, full recharge: Stated as ‘a full charge in under an hour’; 60 minutes is the upper bound, not a precise figure.
  8. 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.
  9. C1000, cell chemistry: LiFePO4 (Lithium Iron Phosphate)
  10. Elite 100 V2, cell chemistry: Tech Specs > BATTERY INFO > Type. FAQ A7: ‘It uses ultra-safe LiFePO₄ (LFP) batteries’.
  11. C1000, cycle life: 3,000 (80% Capacity)
  12. Elite 100 V2, cycle life: Tech Specs > BATTERY INFO > Cycle Life. The ‘+’ means 4,000 is a floor (“over 4,000 cycles” in bullets).
  13. Elite 100 V2, cycle life: 4,000+ Cycles to 80% Original Capacity
  14. C1000, UPS switchover: Stated as under 20 ms; the manufacturer gives an upper bound, not a measured figure.
  15. 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’.
  16. C1000, expandable: Up to Max. 2112Wh Capacity with Expansion Battery (Coming soon.)
  17. C1000, expandable: The expansion battery was marked ‘coming soon’ on the product page when checked; confirm it is actually on sale before counting on it.
  18. 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.
  19. C1000, solar input: Solar Input Recharge: 600W Max, 11-60V MPPT
  20. Elite 100 V2, solar input: Tech Specs > INPUT > Solar Input. FAQ A5: ‘Total VOC: 12V–60V’, ‘Total Power: 1,000W Max’.
  21. C1000, AC input: AC Input Recharge: 1,300W Max
  22. 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.
  23. C1000, AC outlets: AC Outlets: 6×
  24. C1000, USB-C: Two USB-C ports; highest single port is 100W.
  25. Elite 100 V2, USB-C: Tech Specs > OUTPUT > USB-C Port: two USB-C ports, one 100W max and one 140W max.
  26. C1000, app: Wireless Connection for App: Wi-Fi and Bluetooth
  27. Elite 100 V2, app: Tech Specs > GENERAL > Connectivity = ‘WiFi / Bluetooth’. BLUETTI App supports charging-mode selection and Power Memory Mode (FAQ A10).
  28. Elite 100 V2, noise: Condition: under 600W load. Tech Specs > GENERAL > Noise = ’30 dB’.
  29. C1000, warranty: Warranty: 5-Year Warranty
  30. Elite 100 V2, warranty: Tech Specs > GENERAL > Warranty. FAQ A7: ‘it comes with a 5-year warranty’.
  31. C1000, weight: Net Weight: 28.44 lb / 12.9 kg
  32. Elite 100 V2, weight: Tech Specs > GENERAL > Weight. FAQ A2 gives a slightly different figure: ‘It weighs just 25.3lbs(11.5kg )’.
  33. C1000, price: Manufacturer list price when checked; a $20 code brought it to $429.99 that day.
  34. Elite 100 V2, price: List price. Bundles range up to $2,199.00.

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. “Start-up not assessed” appears where the start-up draw meets or exceeds the unit’s continuous rating and the unit states no conventional motor-start surge to check it against (C1000); the hours assume the motor starts.

What the differences mean

Price per watt-hour. At the list prices we checked, the C1000 costs $0.43/Wh against $0.49/Wh for the Elite 100 V2. At list the C1000 is $49.01 cheaper ($449.99 vs $499) for 1,056 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 C1000. Both are two-hands-and-a-flat-surface units; the difference matters if the unit moves between car, porch and basement.

Cycle rating. The Elite 100 V2 is rated for 4,000 cycles against 3,000 for the C1000, 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. 4.00 W/$ on the C1000 against 3.61 W/$ on the Elite 100 V2: 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 two split evenly: the C1000 leads on cost per watt-hour ($0.43/Wh vs $0.49/Wh) and continuous watts per dollar (4.00 W/$ vs 3.61 W/$); the Elite 100 V2 leads on watt-hours per pound (41.0 Wh/lb vs 37.1 Wh/lb) and rated cycle life (4,000 vs 3,000). What decides it is the figure your outage actually tests:

  • CPAP overnight. Switchover: C1000 under 20 ms, Elite 100 V2 up to 10 ms. A 40 W CPAP runs roughly 18–22 hr on the C1000 and 18–21 hr on the Elite 100 V2. 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 C1000 states a boost figure rather than a motor-start surge rating; the Elite 100 V2 states a 3,600 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: C1000 under 60 min, Elite 100 V2 70 min. The C1000 figure is an upper bound, not a measured time, so the two cannot be ranked from published numbers.

A 1,024–1,056 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.
