Figures read C2000 Gen 2 first, DELTA 3 Max second.

Which one suits what

One line per criterion, each with the numbers behind it. There is no overall winner: weigh the lines that matter for your list.

  • Longer runtime on the same load: a tie at 2,048 Wh.
  • Bigger loads at once: a tie at 2,400 W.
  • Motor and compressor starts: the EcoFlow DELTA 3 Max, with 4,800 W against 4,000 W for the C2000 Gen 2. The surge rating covers the start of a fridge, pump or tool.
  • Carrying it: the Anker SOLIX C2000 Gen 2, with 41.7 lb (18.9 kg) against 44.8 lb (20.3 kg) for the DELTA 3 Max. Lighter is easier to move.
  • Price per watt hour: the EcoFlow DELTA 3 Max, with $0.59 against $0.73 for the C2000 Gen 2. Prices as stored for October 2026; sale prices change often.
  • Solar refill: the Anker SOLIX C2000 Gen 2, with 3.4 h of peak sun against 5.5 h of peak sun for the DELTA 3 Max. From empty at each station's own solar limit.
