Home Preparedness › Power & Communication

I Had Three Weeks of Food in the Basement. Then the Power Went Out, and I Couldn’t Reach My Daughter.

If you keep canned goods, bottled water and spare batteries in the house but you have never actually thought through how you would contact your family, there is a gap in your plan. It took me two days in the dark to find mine.

I want to be clear about something up front. I am not a survivalist. I do not have a bunker. I am a 71-year-old woman in a two-bedroom house who pays attention, and who has been through enough winters to take a forecast seriously.

So when the storm came through, I was not worried. I had done this before.

Let me tell you exactly what was in my basement that week:

Three weeks of canned food. Two cases of bottled water. A hand-crank radio. Candles, matches, a first aid kit, and a box of batteries in four sizes. Extra blankets. A camp stove and two propane canisters.

I had thought about being cold. I had thought about being hungry. I had thought about being in the dark.

I had not thought about being unreachable.

The Second Night Is When It Hit Me

The power went out on a Tuesday evening. That first night was almost pleasant, if I am honest. Candles, a book, the radio going in the kitchen.

By Wednesday afternoon my phone was at eleven percent.

I had been using it the way anyone would. Checking the outage map. Texting my daughter in Ohio so she would not worry. Looking at the radar. Nothing excessive.

But here is the part nobody tells you: when the towers near you are struggling, your phone does not quietly give up. It works harder. It keeps hunting for a signal, and hunting is the single most expensive thing a phone can do with its battery.

Mine went from eleven percent to nothing in under two hours.

And that was the moment I understood what I had actually prepared for. I had prepared to survive. I had not prepared to be reached.

My daughter called the sheriff’s department that night because I had gone quiet. A deputy came by at eleven o’clock to knock on my door and confirm that the old woman on Birch Street was fine.

I was fine. I was also mortified.

The Part Almost Every Prepared Household Misses

In the weeks after, I started asking friends what was in their emergency kit. Almost everyone said the same three things: food, water, flashlight.

Not one person mentioned power for a phone.

Which is strange, when you think about it plainly. Your phone is not a luxury in an emergency. It is the single device that does almost everything your emergency plan depends on:

• It is how you tell your family you are alive, which is the thing they actually need.
• It is how you find out what is happening when the radio is vague and the internet is out.
• It is how you call for help, and how help finds you.
• It is your flashlight, your clock, your list of phone numbers you no longer have memorized.

And it is the one item in the entire kit with a hard expiration date measured in hours.

The canned soup will still be soup in a year. The batteries will still be batteries. The phone goes flat by dinnertime on day two, and when it does, every one of those jobs stops at once.

Why the Backup You Already Own Probably Will Not Save You

I owned a power bank when this happened. It was in a kitchen drawer. It was at about thirty percent, because the last time I had used it was a flight eight months earlier.

This is the honest problem with an ordinary power bank. It is a sealed tank. Whatever charge you happened to leave in it is all you get, and once it is empty it is a paperweight until the grid comes back.

The other options people mention have the same flaw somewhere:

• The car. Works, until the fuel runs low or the roads are blocked. And it means sitting in a cold car in the dark to charge a phone.
• A generator. Fine if you own one, can lift it, have stored fuel, and want to run it to charge a telephone.
• The landline. Most of us no longer have one, and the cordless handsets that replaced them need wall power to work at all.

Every one of those depends on something running out. What I wanted was the opposite: something that puts charge back in by itself, without me feeding it anything.

Good News, Though

That search is how I found the Rivanta® Emergency Power Bank, and the reason I ended up writing this.

It is a rugged battery pack, roughly the size of a paperback, with one difference that matters more than any spec on the box: the entire front face is a solar panel. Set it on a windowsill, clip it to a bag, leave it on a porch rail, and it puts charge back in from daylight. No outlet. No fuel. No cord to anything.

What Most People Do Not Know About Their Phone and Satellites

This is the part I wish someone had told me before that Tuesday, and it is the reason I now keep one of these in the hall closet.

If you have a reasonably recent iPhone, and on some newer Android phones as well, your handset can send an emergency SOS message by satellite. No cell tower involved. You step outside, hold the phone toward open sky, and it can get a message out when there is no signal at all for miles.

It is a genuinely remarkable feature. Most people who own it have no idea it is there.

But read the condition carefully, because everything turns on it:

The satellite does not need a tower. It does need your phone to be switched on.

A dead phone cannot reach a cell tower, a satellite, a neighbor, or anyone else. The most advanced emergency feature ever put in a consumer device is worth precisely nothing at zero percent.

So the real question was never whether I could get a message out without towers. It was simpler and far more uncomfortable than that: would my phone still be alive when I needed it to be?

That is the entire job of this device. It is not a gadget. It is the thing that keeps the option open.

What It Actually Does

Plainly, with no adjectives. These are the manufacturer’s own figures:

• About 2 to 2.5 full phone charges for most iPhones and Samsung Galaxy phones.
• Dead to roughly 65% in about 30 minutes on the 20W USB-C port, which is wall-outlet speed.
• Four ways to put charge back in: the solar panel, USB-C, USB-A, or the built-in cable.
• Charges up to three devices at once across USB-C, USB-A and the wireless pad on the back.
• Rated IPX4 splashproof against rain and spills, plus dustproof and shockproof, in a hard ABS and polycarbonate shell with rubber corners.
• Twin LED flashlight built into the end, with steady, strobe and SOS modes.
• A compass on the carabiner clip, and a hook to hang it from a pack or a rail.
• 37 watt-hours, well under the 100Wh airline limit, so it travels in a carry-on.

The flashlight sounds like a small thing. It is not. On the second night of an outage you are hunting through drawers for a flashlight with batteries that may or may not be flat, and here it is already in your hand, attached to the thing keeping your phone alive.

What to Realistically Expect

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 rather the point.

But there is a right way and a wrong way to own one, and the wrong way is how I owned my old power bank. So here is what I actually do.

How It Compares With the Other Options

What Other Owners Say

I went looking for the unglamorous reviews, the ones from people who had actually been through an outage rather than people describing a box.

Why I Ended Up Buying Three

I bought one for myself. Within a month I had bought two more, and I do not think I am unusual in that.

The first went to my daughter, who lives alone. The second went to my neighbor Ruth, who is eighty-three and whose son lives in Arizona. Neither of them would have bought one for themselves. Both of them have one now because I put it in their hands and said keep this in the hall closet.

There is a reason this keeps happening, and it is not sentimentality. An emergency plan that only covers you is not much of a plan. The whole reason my phone mattered that week was so that somebody else would know I was alright. That only works if they can answer.

Rivanta appears to understand this, because their multi-packs are priced for exactly that behavior rather than as a way to inflate an order.

Questions I Had Before I Bought One

Does the solar panel genuinely work, or is it decoration?

It works, with a realistic expectation attached. Rivanta themselves describe the panel as your backup rather than your main charger. Left in daylight it keeps topping the unit up so you are not starting from empty, and in a prolonged outage it is the difference between a battery that recovers and one that does not. It is not a fast way to fill it from flat. Use the wall for that.

How many times will it charge my phone?

About 2 to 2.5 full charges for most iPhones and Samsung Galaxy handsets. In practice, if you are rationing sensibly, that covers a long weekend without ever seeing a low battery warning.

How fast does it charge?

The USB-C port delivers 20W, which takes an iPhone from dead to roughly 65% in about 30 minutes. That is the same speed you would get from a wall plug. The USB-A port and the wireless pad are slower.

What happens if it gets rained on or dropped?

It is rated IPX4, which covers rain, splashes and spills, and it is also dustproof and shockproof. The shell is hard ABS and polycarbonate with reinforced rubber edges. It is built to live in a bag or a car rather than in a drawer, though it is not a diving accessory and should not be submerged.

Can I take it on a plane?

Yes. The TSA limit for a lithium battery in a carry-on is 100 watt-hours, and this unit is 37Wh, so it is comfortably within the rules. It goes in your carry-on, not your checked bag, which is true of all power banks.

What if I decide it is not for me?

Rivanta’s stated promise is a refund within 30 days of delivery if the unit does not deliver reliable backup power when you need it. Check the current terms on the product page before ordering, since published guarantee periods can change.

Being Prepared Is Mostly About Removing Excuses

I do not lie awake worrying about disasters. I am not suggesting you should.

But I have been on the wrong side of a simple, avoidable gap in my own planning, and the part that stayed with me was not the cold or the dark or the inconvenience. It was my daughter, four hundred miles away, calling a sheriff’s department at eleven at night because her mother had stopped answering.

That was entirely preventable. It cost less than fifty dollars to prevent, and I had simply never thought about it.

Food keeps you alive. A charged phone is how the people who love you find out that you are.

If you have already done the food and the water and the batteries, this is the obvious next thing. And if you have not started, it is not a bad place to begin, because it is the one item in the kit that does a dozen jobs at once.
