How we build it
- Formatted exFAT, so Mac, Windows, Linux, Android and iPhone can all read it.
- Every library file is checked against its publisher’s checksum, and every drive is checked file by file against our master copy before it ships.
- Built to order and shipped by us in 5–10 business days. If we ever can’t meet that, we’ll email you a new date and you can cancel for a full refund.
Good to know
- It’s a drive, not a Wi-Fi hotspot. A laptop can share the whole library over Wi-Fi to every phone nearby; the Start Here guide shows how.
- The stick’s brand and colour may vary with supply. The capacity is always 256 GB or more.
- Want every USGS topo map for your state and a printed Field Manual? Choose the Core Drive.
- The offline AI makes mistakes. Check numbers and safety steps against the printed guide.

Questions about The Grid-Down Kit — Pocket Drive (256 GB)
What’s on the Pocket Drive?
Everything in the Grid-Down Kit, already built and checked: the Grid-Down app, The Field Manual and every kit guide, the offline library of about 180 GB (all of English Wikipedia with images, WikiMed, MDWiki, WikEM, public-release Army and FEMA manuals, the USDA canning guide, expert Q&A, Appropedia and energypedia), an offline US street map with OpenStreetMap data for your state, offline AI, reader apps and the library builder.
Which devices can read it?
It’s formatted exFAT, so Mac, Windows, Linux, Android and iPhone can all read it. Plug it into a laptop and open START-HERE.html. An iPhone may open the app file only as a preview without its tools, so keep the PDF guides too.
How is it delivered?
We build it to order, check every drive file by file against our master copy, and ship it in 5–10 business days. If we ever can’t meet that, we’ll email you a new date and you can cancel for a full refund.
Does it work offline? Is it a Wi-Fi hotspot?
Everything on it works with no internet. It’s a drive, not a Wi-Fi hotspot: a laptop can share the whole library over Wi-Fi to every phone nearby, and the Start Here guide shows how. The offline AI makes mistakes, so check numbers and safety steps against the printed guide.
Where does the advice come from?
Public-safety agencies such as FEMA (Ready.gov), CDC, EPA, the National Weather Service, USGS and the Red Cross, plus peer-reviewed research, cited where each method appears. General preparedness information, not medical advice. In an emergency, follow local officials and call 911.
