If You Want Your Family Safe in a Blackout… Plan on Being on Your Own

Did you know storms aren’t the only thing that can take your power?

A storm at least comes with a forecast, but an attack doesn’t. And Homeland Security has warned that extremists have “credible, specific plans to attack electricity infrastructure.”

Unfortunately, the FBI Director told Congress that foreign hackers are targeting “our electrical grid.” He warned they’re getting ready for the day “the time has come to strike.”

And when riots tore through Minneapolis, firefighters “quit responding to arsons,” a state Senate review found.

When a city falls apart like that, even the help you count on can stop coming.

Nobody knows which one comes next. But FEMA tells families they may need to “survive on your own for several days.”

Light and Power for Your Family When Every Backup Dies

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

Tom, one of our engineers, saw it happen. An ice storm left his sister’s family in the dark, and every backup they had went dead.

So he set out to build a backup that needs no outlet and no gas. And he wanted it to cost less than one night in a hotel.

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

TerraCell is a power bank about the size of a phone, with a flashlight built in.

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

Its Four-Panel Solar Capture™ catches the sun on all four panels at once. That’s 4x faster sun charging than a one-panel solar charger.

So every sunny day fills it back up, with no outlet at all.

As long as the sun is in the sky, your family has power of its own: its light and every phone in the house.

Handy when the power went out

Reviewed in the United States

“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!”

Now it’s just me, and I’m ready

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.
