A library that works when nothing else does.

Six million articles, maps, and medical references on a device that makes its own Wi-Fi. No internet, no cell service, no subscription. Your phone just connects.

From $279. Every unit ships sealed with a dated library. Assembled in Minnesota.

A family in a dark living room during a power outage, reading from phones connected to a Blackout Library lit by a lantern.

9:40 p.m., the fourth hour without power. The library is on the coffee table and everyone's phone is connected to it.

How it works

Plug it in. Join the Wi-Fi. Read.

There is nothing to install and nothing to sign up for. The device makes its own network, and any phone, tablet or laptop that joins it lands on the library's home page.

  1. 1

    Plug it in

    A wall outlet, a car charger or a USB power bank. One draws about three watts; a common power bank runs it all night.

  2. 2

    Join the Wi-Fi

    The network name and password are on the card in the box. Up to twenty devices on One; forty or more on Signature and Vault.

  3. 3

    Read

    One search box across everything on the device, and a Right now panel with bleeding, CPR, water, shelter, hypothermia and poisoning one tap away.

Three ways to own the library

Signature and Vault

Ask it a question. It shows you the page.

The Library Assistant runs entirely on the device. It answers only from passages it found in the library and shows the source beside the answer, so you can read it yourself. When the library has no answer, it says so.

  • Answers only from what is on the device, never from memory.
  • Every answer carries its source, and a tap opens the full page.
  • Nothing leaves the device. There is no account and no connection to anything.

Questions people ask first

All questions and answers

Does it need the internet?

No. Not to set up, not to use, not ever. The device makes its own Wi-Fi network and everything is stored on it.

How many people can use it at once?

One serves about twenty phones on its built-in Wi-Fi. Signature and Vault include a separate router and serve forty or more across a whole house.

How long does it run on a battery?

One draws about three watts, so a common 10,000 mAh power bank runs it through the night. Vault carries its own power station, good for about eight hours, which recharges from a wall, a vehicle or a solar panel.

Is the medical information reliable?

It comes from published sources: the CDC, FEMA, the Army manuals, and guides we commissioned from licensed instructors. It is reference material, not a substitute for professional care. Call for help whenever you can.

Can I update the library later?

Yes. Updated libraries are released periodically on a USB stick and apply without an internet connection.
