Choose the PocketBook Verse Pro if you want broad built-in support for personal ebook formats or direct Libby access on a compatible firmware version. Choose Kindle if you mainly buy books through Amazon or use its personal-document delivery; in the United States, most eligible Libby loans can also be sent to a Kindle. The comparison depends on where your books come from and where you live. “Kindle” covers multiple models, so screen, storage, water resistance, and audio hardware need to be compared against a specific Kindle model.
Formats: PocketBook opens more file types directly; Kindle offers Send to Kindle
PocketBook lists support for a wide range of formats on the Verse Pro, including EPUB and DRM-protected EPUB, PDF and DRM-protected PDF, AZW/AZW3, MOBI, FB2, CBR, and CBZ. Its full list also includes ACSM, DOC/DOCX, HTML, DJVU, RTF, TXT, and other formats. These are manufacturer-listed capabilities, not a guarantee that every protected title will open without authorization.
Amazon lists EPUB, PDF, DOC/DOCX, TXT, RTF, HTML, and several image formats for its Send to Kindle service. That is a personal-document delivery route: Amazon processes and sends the document to the account’s Kindle devices or apps. It is not the same as buying an EPUB from the Kindle store, and Amazon’s published guidance does not establish that an EPUB sent this way has every feature or management option of a Kindle-store book.
For protected files on PocketBook, some titles require authorization through Adobe Digital Editions and a matching Adobe ID. PocketBook documents USB and PocketBook Cloud transfer. Amazon also documents USB transfer, with instructions that can vary by device generation. File acceptance and reading-feature support are separate questions: Amazon’s documentation shows that notes and highlights on personal documents can depend on both file type and device.

Which format workflow fits?
- Existing EPUB, PDF, comic, or mixed-format collection: Verse Pro has the more extensive directly listed format support. Check the file’s DRM and authorization requirements before transferring it.
- Files you want delivered through your Amazon account: Send to Kindle accepts EPUB and several other personal-document types, subject to Amazon’s processing and feature support.
- Books bought from a store: A format listed as supported does not mean a title purchased in another store will be DRM-free or portable. Check the seller’s restrictions as well as the reader’s format list.
Library borrowing: PocketBook has direct Libby; Kindle delivery is U.S.-only
On the Verse Pro, PocketBook’s firmware 6.10.3425, dated March 24, 2026, adds the PocketBook x Libby app. OverDrive says the app is available on PocketBooks running firmware 6.10 or higher. The app can be used to find a library, sign in with a library card, browse and search its catalog, borrow books, place and manage holds, return or renew loans, and download or stream supported titles. Borrowed ebooks can be read offline in the built-in reader; library audiobooks can be listened to online.
Libby’s Kindle guidance is explicitly regional: “You can read most Libby books on a Kindle ereader (available in the U.S. only).” In the United States, the flow is to choose “Read With…” and Kindle in Libby, then complete the loan through Amazon. Outside the U.S., do not assume that this Kindle handoff is available. Library participation, card eligibility, and the titles offered vary, so check your library’s catalog and borrowing rules.

Before borrowing on a Verse Pro
- Check that the reader is running firmware 6.10 or later; PocketBook identifies version 6.10.3425 for Verse Pro as the release that added the Libby app.
- Open PocketBook x Libby, find your library, and sign in with a valid library card.
- Search the catalog and borrow or place a hold. Download an ebook for offline reading, or use the online option for a library audiobook.
This update changes older guidance that described PocketBook borrowing only through browser downloads or manual transfers: compatible Verse Pro firmware now includes a direct Libby app.
Reading, audio, and accessibility features

The Verse Pro supports audiobook playback, Bluetooth audio, and text-to-speech according to PocketBook. USB audio is supported through an adapter. Library audiobooks in PocketBook x Libby are a distinct case: OverDrive’s instructions say they can be listened to online, while borrowed ebooks can be downloaded for offline reading.
Firmware 6.10.3425 adds text-size adjustment, bold text, higher contrast for gray text, a dyslexic font, and screen reader mode. PocketBook lists these options but does not establish how well they suit every user or language. If a particular accessibility function is essential, verify its language support and behavior for your use case.

Notes and annotations
PocketBook says the Verse Pro supports highlighting, underlining, comments, and handwritten notes in EPUB and PDF, with synchronization through PocketBook Cloud. Kindle annotation support for imported personal documents varies by file type and device, according to Amazon’s notes-and-highlights guidance. Compare the specific file you read and the exact Kindle model rather than assuming identical annotation support across formats.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Which reader should you choose?
| Your priority | Better fit | What to check |
|---|---|---|
| Opening a varied collection of personal ebooks | PocketBook Verse Pro | Confirm DRM and Adobe ID requirements for protected books. |
| Borrowing Libby ebooks directly on the device | PocketBook Verse Pro with firmware 6.10 or later | Check library participation, card eligibility, and title availability. |
| Sending Libby loans to an e-reader through Amazon | Kindle in the United States | Libby says this is available in the U.S. only and covers most, not all, Libby books. |
| Buying and managing books within Amazon | Kindle | Confirm the model’s display, storage, audio, and accessibility features. |
| Listening to audiobooks or using text-to-speech | PocketBook Verse Pro is a documented option | Check audio source and connection needs; PocketBook lists Bluetooth and USB audio through an adapter. |
If your collection is mostly Amazon purchases, Kindle’s account workflow is the natural fit. If your books come from multiple sources, you use EPUB or other mixed formats, or you want direct Libby access outside the U.S. where your library supports it, the Verse Pro is the stronger match on the documented features here. For hardware, make the final comparison against a named Kindle model, not the Kindle range as a whole.
