This is the tier where preparedness spending goes wrong most often, so it opens with the cheapest item in it. Before anyone spends several hundred dollars on backup power, a fifteen-dollar plug-in meter answers the question that determines whether that money is well spent: what does your household actually draw? Appliance labels report maximums and say nothing about startup surge, which is what actually trips an undersized power station. People buy too small because they trusted a label and too large because a salesperson was cautious. Measurement first is the whole discipline of this tier, and it is nearly absent from consumer preparedness content. When we ran our four-system test, two of the four independently named this meter as the most overlooked item in the entire genre, the strongest convergence signal we found anywhere in the exercise.
The second principle of the tier is that the first backup power purchase for most households should be the one that cannot poison anyone. A battery power station is silent, produces no exhaust, and is safe in a bedroom. A generator produces roughly ten times the power for similar money, and it also produces carbon monoxide, requires fuel logistics and maintenance, and kills people after every major storm when its placement rules are ignored. The generator has a place on this list. Its place is item 93, near the end, after detection, after a battery system, and after the household has learned what its loads actually are. The order is the safety feature.
The threshold
Your household can keep communications, light, and essential devices running through a multi-day outage without burning anything.
Rough tier cost: $600 to $1,500, dominated by the power station and panel. The first item costs fifteen dollars and determines how well the rest is spent.
