The tablet comes in four different colors and offers an ad-free option. Best yet, use Alexa to pull up apps and play music with a quick voice command. And since it’s part of the Kindle line, the tablet doubles as an e-reader, allowing you to take your digital library on the go. Get up to 12 hours of battery life reading the latest novels on the Kindle app. For the avid reader, 189ppi and a 1TB expandable hard drive ensures that a massive digital library can be packed for an on-the-go experience. Thanks to 300ppi, words on the 6-inch display screen are clear and easy to read. And, like the Kindle Paperwhite promises, you can enjoy weeks of battery life on this e-reader. Audible compatibility also helps bring to life your favorite books on the go. Best of all, the Paperwhite is waterproof, so no need to worry about short circuiting it. The 25 built-in LED lights brighten up the 7-inch screen and incorporate warm technology to ease blue light eye strain. Better yet, the Oasis uses auto-adjusting light technology to make sure the light is optimal for your eyes. It comes with Audible technology and up to 32GB of storage space to take a massive digital library with you. The 7-inch display offers great HD options for optimal streaming. And, at 171ppi, you can expect clear text when swapping from streaming to reading. More importantly, while the Kindle Fire 7 Kids Edition comes with expandable storage of up to 512GB, so all their favorite apps and learning games can fit on the device. At around $100, the price for this tablet cannot be beat, especially since it can program multiple profiles for easy, fast learning for the whole family.

Battery life - Battery life is essential for reading into the early hours of the morning or those long commuter train rides. The HD Kindles on this list offer up to 12 hours of battery life, while basic e-readers like the Kindle Paperwhite can provide weeks of battery life on a single charge. Pixels-per-inch (PPI) - For those who want a Kindle solely for reading, then the pixel density is important. PPI can make text crystal clear or a little blurry, depending on its measurement. As an example, the high-end Kindle Oasis can offer up to 300ppi, while the basic Kindle e-reader offers 167ppi. Compatibility - Audible and other in-app experiences offer a plethora of information at the tap of a finger. Tablets in the Kindle Fire line will cater to in-app experiences. With the exception of Audible, the Paperwhite and Oasis serve only as e-readers without any of the fancy extra features, which, depending on your preference, can make or break your reading experience.
