Figures read C1000 Gen 2 first, DELTA 3 Plus 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 1,024 Wh.
  • Bigger loads at once: the Anker SOLIX C1000 Gen 2, with 2,000 W against 1,800 W for the DELTA 3 Plus. Continuous output caps what runs at the same moment.
  • Motor and compressor starts: the EcoFlow DELTA 3 Plus, with 3,600 W against 3,000 W for the C1000 Gen 2. The surge rating covers the start of a fridge, pump or tool.
  • Carrying it: the Anker SOLIX C1000 Gen 2, with 24.9 lb (11.3 kg) against 27.6 lb (12.5 kg) for the DELTA 3 Plus. Lighter is easier to move.
  • Price per watt hour: the Anker SOLIX C1000 Gen 2, with $0.59 against $0.78 for the DELTA 3 Plus. Prices as stored for October 2026; sale prices change often.
  • Solar refill: the EcoFlow DELTA 3 Plus, with 1.4 h of peak sun against 2.3 h of peak sun for the C1000 Gen 2. From empty at each station's own solar limit.
