Figures read R3500 first, E3600LFP 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: the ALLPOWERS R3500, with 3,168 Wh against 3,072 Wh for the E3600LFP. Runtime follows usable watt hours.
  • Bigger loads at once: the Pecron E3600LFP, with 3,600 W against 3,200 W for the R3500. Continuous output caps what runs at the same moment.
  • Motor and compressor starts: the Pecron E3600LFP, with 7,000 W against 6,000 W for the R3500. The surge rating covers the start of a fridge, pump or tool.
  • Carrying it: the Pecron E3600LFP, with 79.4 lb (36 kg) against 92.6 lb (42 kg) for the R3500. Lighter is easier to move.
  • Price per watt hour: the ALLPOWERS R3500, with $0.66 against $0.75 for the E3600LFP. Prices as stored for October 2026; sale prices change often.
  • Solar refill: the Pecron E3600LFP, with 1.7 h of peak sun against 2.1 h of peak sun for the R3500. 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.
