Want Your Family Safe in a Blackout? Plan on Being on Your Own

A storm, a cyberattack, a riot. Any one of them can take your power, and nobody can tell you which comes first.

Washington knows the grid is a target. The FBI Director told Congress foreign hackers are going after “our electrical grid.”

And when riots tore through Minneapolis, even firefighters “quit responding to arsons.”

If help stops coming for a burning building, it won’t come to get your lights back on.

Even FEMA admits your family may need to “survive on your own for several days.”

Your Family’s Own Power When Every Backup Dies

Power banks need an outlet, and generators need gas. A long blackout takes both.

Our engineer Tom saw it happen. An ice storm left his sister’s family in the dark, with every backup dead.

So he set out to build one that needs no outlet and no gas, for less than a night in a hotel.

What’s TerraCell? Your Family’s Own Power, Refilled by the Sun

TerraCell is a phone-size power bank with a flashlight built in.

It holds up to 5 full phone charges and charges three phones at once.

Most solar chargers catch the sun on one small panel. TerraCell opens out to four, and its Four-Panel Solar Capture™ gives you 4x faster sun charging.

So every sunny day fills it back up, and your family has light and charged phones again that night.

So whether hackers, a war or a storm takes the grid down, your family has infinite power from the sun.

Handy when the power went out

“Recently during a winter storm we were without power for 3 days. My TerraCell kept our phones going, and the light on it is additionally handy!”

Reviewed in the United States

“After my husband died I had to learn so much stuff on my own. I was always comfy and cozy and safe knowing he was taking care of everything. I don’t have anyone nearby to help, so now my TerraCell sits out on the porch rail on sunny days, and when the ice storm took the power, I had light and the radio all night.”

Frequently Asked Questions

How many times will it charge my phone?

Up to five full charges from a full battery. And every sunny day fills it back up, so your family keeps its light and its phones going, however long the outage lasts.

How many phones can it charge at once?

Three. It has two USB ports and a USB-C port, so three phones charge together. And fast charging gets them back up quickly.

What can I plug into it?

Anything that charges by USB cable, like your family’s phones, a tablet or a radio. So the things you count on in a blackout keep working.

How do I charge it?

Open its four panels in direct sun, or plug it into a wall socket by its cable. Either way, it fills back up.

Does it have a light?

Yes. It has a built-in flashlight with steady, SOS and strobe. And the sun keeps it charged, so your light never depends on batteries you forgot to buy.

Can I leave it charging overnight?

Yes. Built-in protection stops it from overcharging or overheating, so you can leave it filling up by the bed while your family sleeps.

Can it get wet?

Yes. It’s weather-sealed, so the storm that takes your power can’t take your TerraCell too.

Can I take it on a plane?

Yes. It folds small for a carry-on, and it’s under the airline limit for spare batteries. So it comes along on every family trip.

If the power’s out, won’t the cell towers be down too?

Then your family’s phones are already charged the minute they come back. And its light works with no signal at all, so you can still see your way through the house while you wait.

What if I change my mind?

You have 120 days to decide, for any reason, with every penny back. And every TerraCell has a full year of warranty coverage.

Why can’t I buy this on Amazon or eBay?

We sell direct so we can promise real TerraCells, the full 120-day guarantee and this price.
