ALLPOWERS R1500 vs BLUETTI AC180

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 21). The AC180’s own 15 W draw is included. 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).
