E-Reader questions answered
Updated June 2026Independently researchedNo paid placement.
An e-reader is a dedicated device for reading books with an E Ink screen that’s easy on the eyes, lasts weeks on a charge, and works best for plain text reading. They are not tablets, they do not multitask or support most apps, but they offer a distraction-free reading experience. The key choice comes down to ecosystem (Kindle, Kobo, Nook) versus features like waterproofing or note-taking.
What is an e-reader and how is it different from a tablet?
An e-reader is a single-purpose device built around an E Ink screen, which mimics paper by reflecting light rather than emitting it. This means zero glare outdoors and far less eye strain during long sessions. Tablets like an iPad use LCD or OLED screens that are backlit, can do everything from video to web browsing, but tire your eyes faster and drain the battery in hours. E-readers are deliberately limited. You cannot install most apps, play games, or browse the modern web comfortably. That limitation is actually a feature: it removes distractions and makes you focus on reading. Battery life on an e-reader is measured in weeks, not hours, because the screen only uses power when turning a page. If you want a device strictly for reading novels, articles, or textbooks, an e-reader is the better buy.
Should I buy a Kindle, Kobo, or another brand?
The answer depends on where you get your books and what extra features matter to you. Amazon’s Kindle lineup is the most popular, tightly integrated with the Kindle Store and Audible, plus it syncs your progress across devices. If you already buy e-books from Amazon or have a large Kindle library, that ecosystem is hard to leave. However, Kindle’s file format is proprietary, it does not natively support EPUB files without conversion. Kobo is the main alternative, particularly strong for library users because it natively supports OverDrive and borrows library books directly on the device. Kobo also handles EPUB files natively, making it easier to load books from other stores or free sources. Nook (Barnes & Noble) still exists but has a smaller following and less frequent updates. In general, if you borrow from the library often, choose Kobo. If you buy most books from Amazon, choose Kindle.
Do I need a waterproof e-reader?
Waterproofing is a convenience, not a necessity, but it is a big plus if you read near pools, in the bath, or on the beach. Most mid-range and premium e-readers now carry an IPX8 rating, which means they can survive submersion in fresh water for up to 60 minutes at a certain depth. Models like the Kindle Paperwhite and Kobo Libra 2 have this feature; entry-level models like the basic Kindle or Kobo Nia do not. Even if you don’t plan to drop it in water, waterproofing gives peace of mind during outdoor use. Rain, splashes, or sweaty hands won’t ruin the device. The trade-off is a slightly higher price and a thicker build in some cases. If you read mostly indoors on a couch or bed, a non-waterproof e-reader is perfectly fine.
How long does the battery last on an e-reader?
Battery life is one of the biggest advantages of e-readers over tablets. A typical e-reader with the front light turned off can last four to six weeks on a single charge, based on half an hour of reading per day. That longevity comes from the E Ink screen technology, which holds text without power, electricity is only used when turning a page. If you keep the front light on at a medium brightness, battery life drops to a few weeks. Wireless features like Wi‑Fi and Bluetooth also drain the battery faster. Still, even under heavy use with light and wireless always on, most e-readers last at least a week. A full charge takes a few hours via USB, and many people only charge their e-reader once a month.
Can I borrow library books on an e-reader?
Yes, but the method varies by brand. Kobo is the most seamless: it supports OverDrive directly on the device, so you can search, borrow, and read library books without needing a computer. Amazon’s Kindle also works with library books via OverDrive, but you must use the Libby app or your library’s website to borrow the book, then have it sent to your Kindle. It takes an extra step, but it works well. Nook has its own partnership with OverDrive and libraries, but the process is less streamlined than Kobo’s. If borrowing library books is your primary use, Kobo is often recommended for the convenience. Note that not all libraries are supported, and availability of e-books can vary widely.
What screen size and weight should I look for?
Most e-readers come in two common sizes: 6-inch and 7-inch screens. A 6-inch device (like the basic Kindle or Kobo Nia) is very portable, about the size of a paperback, easy to slip into a small bag or even a large pocket. It is ideal for commuters and casual readers who value portability over screen real estate. Weight is usually under 200 grams, so it’s comfortable to hold for hours. A 7-inch screen (like the Kindle Paperwhite or Kobo Libra 2) offers more text on the page, better for reading in a wider variety of fonts or for reading magazines and PDFs. These models are still lightweight (often around 200–210 grams) but slightly larger in footprint. Larger e-readers (8-inch and up) are made for note-taking or comic reading, but they can be heavier and less comfortable to hold one-handed. You should pick the size that balances how much you read on the go versus at a desk.
Frequently asked questions
Can I read in the dark without a backlight?
No, but most modern e-readers include a built-in front light that illuminates the screen evenly. This is different from a tablet’s backlight, it shines light from the edges of the screen toward your eyes, so it’s easier on the eyes. Models without a front light require a clip-on reading lamp.
Can I install apps like Netflix or games on an e-reader?
Not on any mainstream e-reader. They run on custom, locked-down operating systems designed only for reading. You cannot install third-party apps, browse the full web, or stream video. That limitation is intentional to keep the experience distraction-free.
Do e-readers support audiobooks?
Some do. Amazon’s Kindle Paperwhite and Oasis support Audible audiobooks via Bluetooth headphones. Kobo’s more recent models also support OverDrive audiobooks. Entry-level and older models usually lack Bluetooth and do not play audiobooks.
Can I take notes on an e-reader?
Yes, but only on specific models. Devices like the Kindle Scribe, Kobo Elipsa, and reMarkable allow handwriting or typed notes with a stylus. Standard reading-focused e-readers have no note-taking capability. If you need annotations, look for a model with a stylus.
How do I transfer books from my computer to an e-reader?
Most e-readers connect via USB cable and appear as an external drive. You can drag and drop compatible files (EPUB for Kobo, MOBI for older Kindles) into the documents folder. Kindle also supports sending books via email to your device’s @kindle.com address. For library books, follow the OverDrive or Libby process.
Which e-reader is best for reading comics or graphic novels?
You’ll want a larger screen, at least 7.8 inches, and a color E Ink display if you can find one, like the Kobo Libra Colour or Kindle Scribe (black and white only). Most standard 6-inch e-readers make comics too small to read comfortably. Dedicated comic readers sometimes prefer tablets for color and fast page turns.
