Finding yourself far from a wall socket when your phone hits five percent is positively nervewracking. If you stash a portable battery in your bag, you can avoid that feeling altogether. But there are thousands of power banks out there and it can be tough to pick the right one for what you need. I’ve spent a few years testing dozens of batteries and found the best power banks for different scenarios. Whether you need a quick reup for your phone or a huge brick to keep your laptop alive, you’ll find something fitting here.

Best power banks for 2026

What to look for in a portable battery pack

Battery type

Nearly every rechargeable power bank you can buy (and most portable devices) contain a lithium-ion battery. These beat other current battery types in terms of size-to-charge capacity, and have even increased in energy density by eight fold in the past 14 years. They also don’t suffer from a memory effect (where a battery's lifespan deteriorates due to partial charges).

Flying with portable batteries

You may have heard about lithium ion batteries overheating and catching fire — a recent Hong Kong flight was grounded after just such a thing happened in an overhead bin. Current restrictions implemented by the TSA still allow external batteries rated at 100Wh or less (which all of our recommendations are) to fly with you, but only in your carry-on luggage — they can’t be checked.

Recently, Southwest Airlines was the first in the industry to take that rule one step further. Now, flyers on that airline must keep power banks in clear view when using them to recharge a device. If the portable charger isn’t actively in use, however, it can stay in your carry-on bag in the overhead bin.

Capacity

Power bank manufacturers almost always list a battery’s capacity in milliamp hours, or mAh. Smaller batteries with a 5,000mAh capacity make good phone chargers and can fill a smartphone to between 50 and 75 percent. Larger batteries that can recharge laptops and tablets, or give phones multiple charges, can exceed 25,000mAh and we have a separate guide that covers that entire category. 

Unsurprisingly, the prices on most batteries goes up as mAh capacity increases, and since batteries are physical storage units, size and weight go up with capacity as well. If you want more power, be prepared to spend more and carry around a heavier brick.

You might think that a 10,000mAh power bank could charge a 5,000mAh phone to 100 percent twice, but that’s not the case. In addition to simple energy loss through heat dissipation, factors like voltage conversion also bring down the amount of juice that makes it into your phone. Most manufacturers list how many charges a battery can give a certain smartphone. In our tests, 10,000mAh of battery pack capacity translated to roughly 5,800mAh of device charge. 20,000mAh chargers delivered around 11,250mAh to a device, and 25,000mAh banks translated to about 16,200mAh of charge. That’s an average efficiency rate of around 60 percent.

Wireless

Wireless charging, whether through a bank or a plugged-in charging pad, is less efficient than wired connections. But it is convenient — and in most cases, you can carry around and use your phone as it refills with a magnetically attached power bank.

Power banks with wireless charging are far better than they once were. Just a couple years ago, the ones I tested were too inefficient to recommend in this guide. When batteries adhering to the Qi2 wireless charging standard started arriving in 2023, performance markedly improved.

To gain Qi2-certification, a device has to support speeds of up to 15 watts and include magnetic attachment points. The MagSafe technology on iPhones were once the only handsets that were Qi2-compatible, but now Google’s Pixelsnap tech brings both the higher speed and magnetic grip to Pixel 10 phones. Samsung may follow up with its own version in future releases.

The latest wireless charging standard, Q12 25W, is supported by the new iPhone 17 phones as well as the Google Pixel 10 Pro XL. Battery packs that are Qi2 25W-enabled are starting to hit the market as well, and the Ugreen MagFlow was the first on the scene.

Ports

USB-C ports can deliver faster charges than USB-A ports, and most of the portable chargers we recommend here have Type-C connections. But Type-A jacks are still handy if you need to use a specialized cable for a certain device (my camera’s USB-A to micro USB cable comes to mind).

There’s also variation among USB-C ports. Larger banks with more than one port will sometimes list different wattages for each. For example, a bank with three ports may have two 65W ports and one 100W port. There will also be at least one in/out port on the bank, which can be used to charge the battery itself or to deliver a charge to your device. Wattages and in/out labels are printed right next to the port — and always in the tiniest font possible (remember, your phone is an excellent magnifying glass if you ever have trouble reading them).

As with standard wall chargers, the port’s wattage will determine what you can charge. A phone will happily charge off a 100W connection, but a 15W plug won’t do much for your laptop. And remember, the cable has to match the maximum wattage. A cable rated for 60W won’t deliver 100W speeds.

Luckily, some of the best power banks include a built-in USB-C cable. That’ll not only ensure you have the right cord, it’s one less thing you have to remember to bring along.

Design

Once, most rechargeable batteries were black with a squared-off, brick-like design, but now they come in different colors and shapes with attractive finishes and detailing. While that doesn’t affect how they perform, it’s a consideration for something you’ll interact with regularly. Some portable power banks include extra features like MagSafe compatibility, a built-in wall plug or even a kickstand. Nearly all have some sort of indicator to let you know how much available charge your power bank has left, usually expressed with lighted pips near the power button. Some of the newer banks take that a step further with an LED display indicating remaining battery percentage.

How we test best power banks

First, I considered brands Engadget reviewers and staff have tried over the years and checked out customer ratings on retail sites like Amazon and Best Buy. Then, I acquired the most promising candidates and tested them in my home office.

Amy Skorheim for Engadget

For testing, I used each battery to charge both an iPhone and an Android phone, as well as an iPad and a MacBook Pro for the larger portable chargers. I let the devices get down to between zero and five percent and charged them until the devices were full or the power bank died. 

For reference, here are the battery capacities of the device I've used for testing over the years:

• iPhone 11: 3,110 mAh

• iPhone 14 Plus: 4,325 mAh

• iPhone 15: 3,349 mAh 

• iPhone 16: 3,561*

• Galaxy S22 Ultra: 4,855mAh

• iPad Air: 7,729mAh

• 16-inch M1 Pro MacBook Pro: 27,027mAh

*The iPhone 17 has a slightly larger battery at 3,692mAh

I continuously update this guide as companies release new products.

Other power banks we tested

Here are a few picks that didn't quite make the cut, but are worth mentioning. 

Belkin Stage PowerGrip

If you’re into iPhonography, this clever accessory could be worth a look. Belkin’s Stage PowerGrip is a 9,300mAh power bank that has both a wireless charging pad and built-in cable. But it’s also a Bluetooth shutter with a quarter-inch tripod thread. The design resembles a standard digital camera and provides a sturdy grip once you magnetically attach your phone (make sure you’re either using a MagSafe case or no case to ensure a solid connection).

The shutter is conveniently placed and the remote speed was quick enough to capture the cute things my cat was doing. The accessory can even act as a stand while it charges in either landscape or portrait orientation. As a power bank, it’s slow, taking about two hours to get my iPhone 16 from three to 98 percent, but it has enough juice for a full refill plus a little more, which could help if you’re out taking pictures all day.

Anker MagGo for Apple Watch power bank

The Anker MagGo for Apple Watch power bank combines a 10K battery with a built-in USB-C cable and a pop-up Apple Watch charger. I didn’t formally test it as it’s a little too niche, but it deserves a mention for saving my keister on two occasions. Driving to a hike, my watch told me it was down to 10 percent. Thankfully, I had this and could refill the watch before I got to the trailhead. Later, on an interstate trip, I realized the travel charging station I’d brought was a dud. This kept my watch alive for the week I was away. It does a good job simply charging a phone via the handy on-board cable, too. But for those with an Apple Watch, it’s extra useful.

HyperJuice 245W

Hyper’s massive-but-sleek brick is one nice looking power bank. The HyperJuice 245W packs a hefty 27,000mAh capacity, enough to refill my tester phone about four times and get a MacBook Pro from near-dead to 75 percent. It only has USB-C ports, but you at least get four of them. USB-C only is probably fine for most situations, but a USB-A port would be nice for charging the occasional older peripheral. The 245 wattage is pretty high for a power bank and it was indeed speedy. It filled a Samsung Galaxy S24 Ultra in just over an hour. But it’s the same price and capacity as our Mophie Powerstation pick for laptop banks, and that one has a better variety of ports. Hyper’s battery is also comparable to Anker’s laptop battery, which is cheaper, has built-in cables and has nearly the same capacity. Plus, that bank is just as swanky looking.

EcoFlow Rapid magnetic power bank

I was curious to try out the first power bank from EcoFlow, a company that primarily makes larger power stations and whole-home backup batteries. The first offering in the brand’s Rapid series is a Qi2-enabled magnetic charger with a 5,000mAh capacity. It looks quite nice with shiny silver accents and soft-touch grey plastic on the MagSafe-compatible front. There’s a little pull-out leg that sturdily displays your phone as it charges and the attached USB-C cable lets you refill devices directly, then tucks out of the way when it’s not in use. But it didn’t outperform our top pick in the MagSafe category, in terms of both charging speeds and the amount of charge delivered.

Mophie Snap+ Powerstation Mini

The Mophie snap+ Powerstation Mini is terribly well-built. It feels premium with a rubberized contact point for the MagSafe charging pad and a stand that runs the entire width of the bank itself, making it extra sturdy. It’s compact, too, but only carries a 5,000mAh capacity, which gets you a partial charge on most newer or larger phones. Our current MagSafe/iPhone pick has double the capacity, a stand and a digital display — for just $20 more than the Powerstation Mini.

Power bank FAQs

What's the difference between a portable power bank and a portable charger?

A slew of terms are used to describe power banks, including portable batteries, portable chargers, external battery packs and even, somewhat confusingly, USB chargers, which is what wall chargers are often called. They all mean the same thing: a lithium ion battery that stores a charge so you can refill a smartphone, tablet, earbuds, console controller, ereader, laptop, or just about any other device with its own built-in, rechargeable battery. 

There’s little difference between the terms, so the specs you’ll want to pay attention to are capacity (expressed in mAh), size and weight so you can find the right balance between recharging what you need and portability.

Power stations, on the other hand, are distinct. These are bigger units (often around the size of a car battery) that can be used to charge multiple devices multiple times, but notably, they can’t be taken on airplanes.

Does fast charging actually ruin your battery?

Not exactly. The real enemy of a battery’s longevity is heat. The faster you charge a battery, the more heat is generated. Modern phones have features that keep the battery cool while charging, like physical heat shields and heat sinks, as well as software features that slow down processes that generate too much heat. Phone manufacturers are keen to promote a phone’s fast-charging abilities, so they had to figure out ways to make faster charging work.

While there aren’t long-term studies on what fast charging does to a phone, a study on EV batteries (which use the same general concept of charged lithium ions flowing from one side of the battery to the other, absorbing or releasing a usable charge) showed a very slight decrease in capacity over time with only fast charging — though what actually made a larger difference was how hot the battery itself was, due to ambient temperatures, when it was charged.

In short, fast charging could be slightly harder on your battery than normal charging. But the safeguards most smartphones have make that difference fairly negligible. To really ensure you’re optimizing charging capabilities, limit your phone's heat exposure overall.

Can you use a power bank for all your devices?

That depends on the size of the bank and the size of your device’s battery. A small 5,000mAh battery isn’t strong enough to charge laptops, but a portable charger with a 20,000mAh capacity will give your computer a partial refill. You also have to consider port compatibility. If your device has a USB port, you’ll be able to easily find a cable to connect it to a battery. If your device has a more unique port, such as a DC port, you won’t be able to use a battery. Devices with an AC cable and plug can be charged, and sometimes powered (such as in the case of a printer or speaker), by larger laptop batteries with AC ports.

Color is the buzziest feature in ereaders right now, but is it necessary? It makes the covers more fun, and readers of comics and graphic novels will appreciate the added hues (though they may be happier with an E Ink tablet for better image detail). Color is just one factor to consider when picking out the best ereader. The lights, screen quality, housing and buttons make a difference too. Then there’s the software: Do you want to stay in the Kindle ecosystem or get a device that can handle lots of apps? We tested more than a dozen ereaders to come up with our recommendations. This guide also points out ways to get the most out of your new e-book companion once you pick your favorite.

Best ebook readers for 2026

 

What to look for in an ereader

Plenty of apps, including the Kindle app, will let you download and read digital books on an iPhone, Android Phone or tablet. But what makes ebook readers different is the screen: nearly all of them use technology from a company called E Ink. It manufactures electronic paper displays (EPD) composed of three sheets: one containing millions of microcapsules filled with black and white ink particles sandwiched between transparent electrode layers. When a charge is applied, either the black or white particles shift to the top, forming letters and the whitespace around them. 

Color ereaders add a color filter array on top of the standard black and white microcapsule layer. The result is two different resolutions on one screen — the color clarity is 150 dpi while black and white images and text are still 300 dpi.

Because these displays are so different from standard backlight LED panels, you can expect most good ereaders to do a number of things well. They’ll be easier to stare at for long periods of time and easier to read in direct sunlight. Also, since E Ink displays only require power to rearrange the ink, these devices have much longer battery lives than even the best tablets: we’re talking weeks on a single charge, not days.

The ereader market is not as saturated as, say, the smartphone market, but there are still plenty of options out there and they do have small but important differences among them. They tend to range from around $100 to more than $400, though usually the higher end options are stylus-enabled read/write E Ink tablets like the Kindle Scribe. Beyond price, you should consider physical properties like buttons, lights, storage and resolution, as well as how the software lets you find and access books.

Reading features

With any ereader, you’ll navigate the OS via taps and swipes, and some add physical page-turn buttons. Most with built-in buttons have an auto-rotating screen so you can press with your right or left hand.

As E Ink technology has advanced, resolution has greatly improved – even the budget Kindle ereader has a 300 ppi display. You can still find models with lower resolution, but we don’t recommend them.

Some ereaders have front LEDs that support light temperature adjustment. That means you can switch to a warmer light after the sun goes down, which will feel easier on the eyes. If you’re concerned about blue light, you should go for a reader with that feature. Finally, dark mode is available on most later model ereaders, allowing you to invert the black and white text and background, which some people find easier to read in low-light settings. 

Other features

The capabilities of these pocket libraries have advanced considerably since the early days. In addition to storing books, some let you browse the web, run apps and play music. The screen’s frame rate can’t handle gaming, but it’s good enough to show you the Wikipedia entry for Striver’s Row while you read Crook Manifesto.

If you listen to audiobooks, you may want a Bluetooth-enabled ereader capable of playing them. Most of the models we tested have that ability, with the notable exception of the Nook ereader we tried. Keep in mind that audiobook files can take up more space than print files so you'll probably want a device with a higher storage capacity if you plan on doing a lot of listening.

Above all, you should consider where and how you intend to find books to read. Most ereaders make it easiest to shop through their own digital bookstores, but all of them (even Kindles) will now let you download titles from other sources, like libraries, unaffiliated ebook sellers and free public domain sites.

How to get books for your ereader

Kindle, Nook and Kobo all have their own stores that you access directly from each brand’s devices. Prices are the same among all sellers, too. Publishers set the price of an ebook, not the retailer, so a title will cost the same at Amazon, Barnes & Noble, eBooks.com and the Kobo store.

Amazon offers Kindle Unlimited for $12 per month, and it includes four million titles from which you can pick your next read. It includes audio and ebooks, but you won’t find many big, new releases or older bestsellers. Kobo has a subscription called Kobo Plus with about 1.3 million titles: it goes for $8 per month for ebooks only, $8 for audiobooks only or $10 for both.

Buying a book from a proprietary store instantly delivers it to your device, provided you’re connected to WiFi. It also syncs your reading across devices and apps, so you can pick up where you left off on your phone if you forgot your ereader at home. It truly is the most convenient way to go, but if you don’t want to be locked into one brand’s store, or if you opt for an ereader without its own marketplace, you do have options.

How to upload ePubs onto an ereader

Stores like ebooks.com and Google Play have millions of ebooks for sale as digital rights-managed (DRM) ePub files, which Kobo, Nook and PocketBook readers can read in their native ereader apps. Kindles don’t support DRM ePub files at all and Boox devices require third party reading apps (of which there are many) to read those files. Titles from Apple Books are only readable in iOS devices. 

Titles from some publishers like Tor and public domain classics from sites like Project Gutenberg are also sold as ePubs, but without the added DRM. Consequently, Kindles and the Boox Neoreader do support those files. Books you get from third-party sources will look just like ones you bought from a proprietary store, thanks to the flowable, formatted nature of ePub files. While these device-agnostic ebook collections give you extra options for finding your next read, they require a few additional steps to get the files onto your ereader.

To do so, you’ll typically need a computer running a free program called Adobe Digital Editions (ADE). After buying and downloading the ePub file, open ADE and plug your ereader into your computer (all readers here have a USB-C port for charging and data transfers). Your device should pop up in the left panel. Drag and drop the ePub file from your downloads folder into the main panel in ADE. The file will display as an image of the book cover. Drag that image onto your device on the left panel. If the file includes digital rights management (which protects against unauthorized copying) you’ll need to authorize your ereader, which requires using or creating a free Adobe ID. Once you’ve finished adding files to upload, eject the reader from your computer to complete the transfer process.

Kindles use a web-based uploader instead of the ADE method. But since Kindle uses its own proprietary DRM technology instead of Adobe's, the only files it can accept from third parties are non-DRM files, such as from Tor Publishing or Project Gutenberg. After downloading a compatible ePub file, drag and drop it into your browser with the Send to Kindle page open. As long as you’re signed into Amazon, this wirelessly transfers the files to your associated device.

Boox also uses a browser uploader called BooxDrop (along with many other methods) to deliver ePubs to the device. Open it from the Boox App menu and you’ll see a device-specific url. Type that into your browser to access a file delivery portal that uploads to your library. Boox’s built-in ereader app, NeoReader, also doesn’t support files with DRM, so you won’t be able to read current titles from most publishers using that app. Fortunately, Boox devices run nearly every ereader app out there, Kobo and Kindle included, letting you access ePubs any number of ways.

Recently, Bookshop.org, the online seller of physical books that supports indie bookstores, started selling ebooks and up to 100 percent of the profits will go to local booksellers. The company uses a different rights management system than ADE so, right now, you can only read titles you buy from them on the Bookshop.org app, but the company is working with the makers of both Kindle and Kobo to extend compatibility to those ereaders.

How to read library books on an ereader

Your local library card lets you borrow audio and ebooks through a program called Overdrive and its companion app Libby. On a Kobo, you have have built-in access to Overdrive in a separate tab. Once you’ve linked your public library card, the search function will include results for titles available from your local library system; a few taps will upload your selections to your device for the length of the loan. I personally find it easiest to borrow the title I want through the Libby app on my phone. After that, the book pops up on my Kobo’s home screen once the device syncs.

To read library books on a Kindle, you can either go through the Libby app or the Overdrive section of your library’s website. Once you click Borrow, you’ll see the option to “Read now with Kindle,” which takes you to Amazon’s site to sign in. After that, the book will be delivered to your device the next time it connects to WiFi.

For other ereaders, you’ll go through your library’s Overdrive portal and download the ePub after clicking the Borrow button. You can then use the ADE process we described above. Devices that run external apps, like Boox's Page, Go Color 7 or Palma, allow you to read library books via the Libby app, just as you would on a smartphone or iPad.

You can also use the Libby app to borrow audiobooks, but you won’t be able to access them through your ereader. (The exception is an ereader, like a Boox device, that allows external apps). I found it was easier to listen to an audiobook on my phone anyway, regardless of whether I borrowed it through Libby or bought it from Kindle or Kobo.

How we test ereaders

When putting together any guide, the first thing we do is spend hours researching the field. We look at what’s available, what’s new, and what shoppers and professional reviewers have to say. Then we narrow a list to the best candidates for hands-on testing.

Over the course of the past three years, I’ve tested just over a dozen ereaders, representing five different brands: Amazon, Kobo, Barnes & Noble, Boox and PocketBook. I bought, borrowed and uploaded books for each device using the methods above. I used each one for between a few days to a few months. I evaluated each one in the areas of book access, ease of reading, extra features and overall value. Here’s everything we tested so far:

• Amazon Kindle (2022)

• Amazon Kindle (2024)

• Amazon Kindle Paperwhite (2021)

• Amazon Kindle Paperwhite Signature (2024)

• Boox Go Color 7

• Boox Leaf 2

• Boox Page

• Boox Poke 5

• Boox Palma

• Kobo Libra 2

• Kobo Libra Colour

• Kobo Clara 2E

• Kobo Clara Colour

• Kobo Nia

• NOOK GlowLight 4

• PocketBook Era

Other ereaders we tested

Amazon Kindle Colorsoft

Amazon’s first color Kindle impressed with its quick page-turns and load times, auto-adjusting front light and, of course, a decently striking color E Ink display. But at $280, it’s more expensive than all of the other color ereaders in its size range, including the Kobo Libra Colour and the Boox Go Color 7.

Also, some Colorsoft owners reported seeing a yellow band at the bottom of their ereader’s display. This issue did not affect our first review unit during the original testing period, but it eventually appeared. An Amazon spokesperson told Engadget: "A small number of customers have reported a yellow band along the bottom of the display. We take the quality of our products seriously—customers who notice this can reach out to our customer service team for a replacement or refund, and we’re making the appropriate adjustments to ensure that new devices will not experience this issue moving forward."

Amazon sent us a new Colorsoft ereader at the end of 2024 and it does appear that the fixes the company made resolved the yellow-band issue. The screen on our second review unit appears warmer overall, but not overly so. It’s more akin to the screen on the Kobo Libra Colour, and that’s a good thing.

Boox Go 7 stylus-enabled ereader

Boox recently released two new stylus-enabled generations of their seven-inch reader: The monochrome Go 7 and a color-screen Go Color 7 (Gen II). After trying out the stylus-enabled Go 7, I still like the standard, non-stylus enabled version better. True, I liked the Notebook app with its array of handwriting templates and I appreciated the low-to-no latency with the stylus. It also offers a good assortment of brush, pen and style options. But outside of the Notebook app, I didn’t find much use for the stylus.

I was able to doodle in the margins of DRM-free books in Boox’s native NeoReader, but it doesn’t work in other apps or on any rights-managed books. There's a FreeMark option that allows you to draw or write atop any app, but it saves your doodles as separate images, as opposed to allowing you to mark up the page itself. I also found enabling the stylus to be a little glitchy. If you plan to do a lot of writing, you’ll probably be better served by an E Ink tablet, but if you want an ereader that can mark up your books, I suggest going with the Kobo Libra Color, detailed above.

Ereader FAQs

What's the difference between an ereader and an e-ink reader?

Really, they are the same thing. E Ink is a company that designs and manufactures the paper-like screens found in most ereader devices. Technically, anything you read ebooks on can act as an ereader, so your phone, iPad or Android tablet could all serve that purpose, but they’re not considered dedicated ereaders. While there are some devices marketed as ereaders that have LCD or OLED screens instead of E Ink, they aren’t as common. One of the benefits of ereaders is the E Ink screen’s paper-like quality, which causes less eye strain for many people.

But there is a difference between ereaders and E Ink tablets. These larger e-ink devices also employ E Ink screens, but they have stylus input and are often used for note taking and other tasks in addition to reading ebooks. We have an entire guide devoted to helping you pick out an E Ink tablet.

Are there ads on my ereader?

The base model Kindle and Kindle Paperwhite come with ads by default, but you can opt to pay $20 to remove them, either at the time of purchase or after you start using the device. The ads are limited to the lockscreen and are typically for other books or Kindle services. Kobo and Boox ereaders don’t come with ads.

Which ereader has the longest battery life?

Of the devices we tested, the Boox Go Color 7 has the largest listed battery capacity at 2,300mAh (Amazon doesn’t list the capacity of its Kindle devices). But thanks to the nature of E Ink screens and the relatively limited processing power required to display e-books, nearly all ereaders can go for weeks before they need a recharge. That means battery life probably isn’t as much of a deciding factor in buying an ereader as it would be with a tablet or smartphone.

Which ereaders can read Kindle books?

Amazon’s Kindle ereaders are the obvious answer, but other devices capable of running apps can also read titles from the Kindle store. For example, you can download the Kindle app on a Boox ereader through Google Play (the store comes standard in the Boox app menu). You can then sign into your Kindle account and access all the books in your library — the same way you’d read Kindle books on your phone or tablet.

Can you buy Kindle books without a Kindle?

Yes. You can buy Kindle books through the Kindle app or through Amazon’s website via a browser. You can read those titles on a Kindle or any device that can run the Kindle app, such as a smartphone, tablet or computer. Just be aware that Kindle titles can only be read through one of Amazon’s ereaders or the Kindle app. The company uses proprietary digital rights management on all ebooks it sells that can’t be read by other ereader apps like Kobo or Adobe ADE.

What's the difference between Kindle and Kobo?

Both Kindle and Kobo are brands of dedicated ereaders that support searching, buying, downloading and reading ebooks from their own stores. Both also support borrowing books from your local library via Overdrive and Libby.

The difference is that Kindle is owned by Amazon and uses the Kindle store, whereas Kobo is owned by Rakuten and its books come from the Kobo store. Both stores come pre-loaded as a tab on their respective ereader and both carry most in-print books. Each store also carries their own exclusive ebooks as well, but Amazon’s library of Kindle-only books is much larger than Kobo’s. Amazon also offers Amazon Original stories to read on the Kindle, which are free short fiction and nonfiction reads that are free to Prime members.

Which ereader is best for library books?

Both Kobos and Kindles have simple systems for borrowing library books. Other ereaders, like Boox, let you borrow books after downloading the Libby App. Only Kobo ereaders let you search for and borrow books directly on the ereader, with a dedicated Overdrive tab. Kindles, on the other hand, utilize a convenient “read on Kindle” function from the Libby app or website. You can send a borrowed book to your Kindle just by signing into your account. Both methods are pretty easy, so which is the best for you probably depends on other factors than just the library-book feature.
