A Retired Dispatcher Told Me Which Call Floods 911 During a Blackout. It Is Not the One You Would Guess.

Forty-one years on the desk taught Ray Mendel that the calls stacking up in an outage are almost never emergencies. They are families who cannot reach somebody. Here are the five things he told me over coffee, and the one he keeps in his own hall closet.

I am 68 years old and I have been writing about household preparedness for eleven years, which means I have written the checklist more times than I can count. Water. Canned food. Batteries. A radio that does not need the grid.

I had never once put a phone charger on that list.

Then last spring I sat across a diner table from a man named Ray Mendel, who spent forty-one years taking emergency calls for a county in the upper Midwest, and he corrected me inside of ten minutes.

I am going to give you the five things he told me, in the order he told them. The fifth is the reason there are now three of these in my family instead of one.

The calls that pile up in a blackout are not emergencies. They are people trying to find their mother.

I asked him what a bad storm night actually sounds like on the other end of the line. I was expecting fires, downed lines, medical calls.

"You get those," he said. "You always get those. But those come in the first few hours and then they taper. What does not taper is the other kind."

The other kind is the welfare check. Someone two states away calls the non-emergency line because Mom stopped answering. She was texting at four o'clock. It is now nine and there is nothing, and the news is showing the county under a red banner.

"Nine times out of ten that woman is fine," Ray said. "She is sitting in her kitchen with a candle. Her phone died at six and she has no way to charge it. So her daughter calls us, and we send a deputy out to knock on a door, in the middle of the worst night that county has had in years, to confirm something the woman could have told her herself for free."

He was not annoyed at the daughters. He was clear about that. He said he would make the same call about his own mother.

Your phone dies fastest on precisely the night you need it most, and there is a mechanical reason for it.

This was the part that genuinely surprised me, and I have since confirmed it with two people who work in wireless.

When cell service in your area is degraded, because a tower is down or running on its own backup or simply swamped by everyone calling at once, your phone does not quietly wait. It hunts. It steps up transmit power and searches again and again for something to connect to.

Searching for a signal is one of the most expensive things a phone can do with its battery. A handset that would comfortably last you a day and a half of ordinary use can flatten in a few hours when it is hunting.

"Everybody budgets their phone battery like it is a normal Tuesday," Ray said. "Outage nights are not normal Tuesdays. The phone burns faster exactly when you can least afford it."

So the mental arithmetic most of us do, the "I have got half a battery, that will see me through," is wrong in the one situation where being wrong costs the most.

The backup most homes already own is a sealed tank, and nobody knows how full it is.

I told him I owned a power bank. It was in a kitchen drawer. I had last used it on a flight, and I could not have told you within fifty percent how charged it was.

Ray laughed and said that is the standard answer.

The problem with an ordinary power bank is not that it is bad. It is that it is a closed tank. Whatever charge you happened to leave in it months ago is the entire supply. When that runs out it is a paperweight until the grid comes back, which is the precise moment you needed it.

He walked me through the alternatives the same way, and each one has a hole in it:

• The car. Works, until the tank runs low or the road is blocked. And it means sitting in a cold car in the dark to charge a telephone.
• A generator. Fine if you own one, can move it, have fuel stored safely, and are willing to run it to charge a handset.
• The landline. Most households no longer have one, and the cordless handsets that replaced them need wall power to work at all.

Every one of those depends on a supply that is being used up. What Ray wanted, and what he eventually went looking for, was the opposite: something that puts charge back in by itself, without being fed anything.

He asks four questions about any backup power. Most of the category fails at least two.

This is the part I found most useful, because it is a test you can run yourself on anything, including whatever you already own.

These are one retired dispatcher's personal criteria, not an official standard. I found them a more useful filter than any spec sheet.

One unit protects one household. Most of us are responsible for more than one.

At the end he said something I have thought about ever since.

"You are not really buying this for you," he said. "You are buying it so the people who would worry about you do not have to call a stranger to find out if you are alive. And if that is the point, then ask yourself how many households would call about you, or how many you would call about."

For me the honest answer was three. Myself. My daughter, who lives alone four hundred miles away. And my neighbor Ruth, who is 83 and whose son is in Arizona.

So what passed his four questions?

I asked him what he keeps. He told me, and then I went and checked it myself against his own four questions, which seemed like the only fair way to judge it.

It is the Rivanta® Emergency Power Bank. It is a rugged battery pack roughly the size of a paperback, and the thing that separates it from the one in my kitchen drawer is that the entire front face is a solar panel.

One thing the company says that made me trust the rest

Rivanta's own product page states plainly that the solar panel is your backup, not your main charger. You fill it from the wall, and daylight keeps it topped up when the wall is not an option.

That is the correct way to think about it, and I will say honestly that a company telling me what its headline feature does not do bought more credibility with me than any claim on the box.

How it compares with the other options

The way to buy it, which is to test it

Ray's advice on this was blunt and I am passing it along exactly.

That last point is the company's stated promise: a refund within 30 days of delivery if it does not deliver reliable backup power when you need it. Check the current terms on the product page before you order, since published guarantee periods can change.

What owners say

I went looking for the unglamorous reviews rather than the enthusiastic ones. These are reproduced from the manufacturer's published customer reviews.

Why I ended up with three

I bought one. Within a month I had bought two more, for the two households in Ray's question.

Neither my daughter nor Ruth would have bought one on their own. That is not a criticism of either of them. It is just that this is the sort of thing nobody gets around to until somebody hands it over and says keep this on the closet shelf.

Rivanta prices the multi-packs for exactly that behavior rather than as a way to pad an order, which is the only reason I am mentioning it.

Questions I had before I bought one

The whole thing, as plainly as Ray said it

Food keeps you alive. Water keeps you alive. Neither of them tells your daughter that you are.

That message is the entire job of a charged phone in an emergency, and it is the one item in the kit with an expiration measured in hours rather than years. Every other thing on the shelf will still be there in a year. The phone goes flat by dinnertime on day two, and when it does, a dozen jobs stop at once: the calls, the alerts, the flashlight, the list of numbers none of us have memorized anymore.

I am not going to tell you this changes your life. It sits in a closet doing nothing for months at a time. That is the point of it.

But it costs less than fifty dollars to close the one gap that sends a deputy to knock on a door at eleven at night to tell a daughter four hundred miles away that her mother is fine.
