Charged today ยท full refund if the ship date moves
No signal needed. The e-ink screen only uses power when the page changes, reads clearly in direct sun, and charges from any USB-C power bank or small solar panel.
Heavy-Duty Carry Case
A rugged hard-shell case made for the Index. The foam insert holds the device snugly, with a pocket for the charging cable, so everything stays together in a go-bag, car or drawer until you need it.
Ships with your Index.

Built for the days without power
An e-ink screen only uses power when the page changes, so the Index sips its battery while a phone burns through it. When it does need a charge, any USB‑C power bank or small solar panel will do.

Plain answers to fair questions
Does it need internet or a signal?
No. Everything is stored on the device, so it works anywhere, with no Wi-Fi, data or cell signal.
How do I charge it?
With any USB-C charger, power bank or small solar panel.
Is there a subscription?
No. You pay once and the library is yours.
Can I add my own files?
Yes. You can add your own PDFs, books and documents.
Does it have GPS?
No. The offline maps show roads, trails and terrain, but it won’t show your live location. That also means it doesn’t track you.
When does it ship?
Pre-orders ship in March 2027. If that date ever changes, we’ll email you right away and you can choose a full refund.
