Figures read Mega 2 Pro first, E2400LFP 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: the OUPES Mega 2 Pro, with 2,500 W against 2,400 W for the E2400LFP. Continuous output caps what runs at the same moment.
  • Motor and compressor starts: not comparable, because the Mega 2 Pro figure is not published.
  • Carrying it: the Pecron E2400LFP, with 45.2 lb (20.5 kg) against 48.7 lb (22.1 kg) for the Mega 2 Pro. Lighter is easier to move.
  • Price per watt hour: the Pecron E2400LFP, with $0.73 against $0.78 for the Mega 2 Pro. Prices as stored for October 2026; sale prices change often.
  • Solar refill: the OUPES Mega 2 Pro, with 2.7 h of peak sun against 3.4 h of peak sun for the E2400LFP. From empty at each station's own solar limit.

Running time, side by side

Each appliance on its own on a full charge, at 85% efficiency. Loads used for minutes a day show minutes of use.
