50 models, best first. Each bar compares a model with the rest of this list: the best on every point would score 100.
Scores reward a low price per watt-hour, high output, room to expand and long warranties, all as the makers state them. They don't measure real-world efficiency, noise or app quality, so use them to shortlist, then read the model pages.

Price per Wh, lower is better.
Warranty, higher is better.
Each criterion is scored against the best of these 50 models: the best gets 1, and a model with 80% of the best value gets 0.8. For price per wh, lower is better, so the lowest value scores 1 and one 25% higher scores 0.8.
Each scaled value is multiplied by its weight, and the results are added up to a score out of 100. Models with the same score share a rank.
A model is ranked only if it has its own page here and a value for every criterion.
Only models that can run a refrigerator (16 cu ft) are ranked: 725 W, and 2,175 W for a moment as its motor starts. Hours on one charge = capacity × 0.8 (the share Jackery uses in its own runtime formula) ÷ 73 W (its average draw over a day).
A fridge is the first thing most people want to keep on when the power goes out. We use the figures for a frost-free 16 cubic foot refrigerator: 725 W while the compressor runs, from Virginia Cooperative Extension, and about 1,759 Wh a day, from the U.S. Department of Energy brief on typical appliances. A motor draws about three times its running power for a moment as it starts, so a model is ranked only if it can supply 725 W and that starting surge.
The compressor cycles on and off, so a fridge averages about 73 W over a day. Hours on one charge are the battery capacity times 0.8, the share Jackery uses in its own runtime formula, divided by that average. Capacity carries half the score, because it decides how long the food stays cold. Price per Wh counts 30 percent and warranty 20 percent.
Your fridge may use more or less than this one. Check the label inside the door or its EnergyGuide sticker, and use the runtime calculator to add a freezer, lights or a phone charger. Keep the doors shut during an outage so the cold lasts longer.
