Figures read R1500 first, AC180 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 1,152 Wh.
  • Bigger loads at once: a tie at 1,800 W.
  • Motor and compressor starts: the ALLPOWERS R1500, with 3,000 W against 2,700 W for the AC180. The surge rating covers the start of a fridge, pump or tool.
  • Carrying it: the BLUETTI AC180, with 35.3 lb (16 kg) against 36.8 lb (16.7 kg) for the R1500. Lighter is easier to move.
  • Price per watt hour: the BLUETTI AC180, with $0.43 against $0.78 for the R1500. Prices as stored for October 2026; sale prices change often.
  • Solar refill: the ALLPOWERS R1500, with 2.4 h of peak sun against 3.1 h of peak sun for the AC180. 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.
