The ALLPOWERS R1500 runs an average fridge about 21% longer: 13.9 h vs 11.5 h. The BLUETTI AC180 costs $40 less (makers’ prices, Oct 23). The AC180’s own 15 W draw is included. ALLPOWERS lists no own-draw figure for the R1500, so the real gap is likely smaller. The gap shrinks at higher loads, where own draw matters less (table below).

Pick the R1500 for longer fridge runtimes and faster solar refills; pick the AC180 for the lower price ($40 less) and cold garages (works down to −4°F).
