Amazon. has updated its range of tablets and Fire TV products while announcing an all-new 7-inch Fire tablet that will cost just $50.

Amazon boasts the new device has the best display on any tablet under $50. The company says the budget tablet will be twice as durable as the latest-generation iPad Air from Apple, and features twice the processing power of Samsung's Galaxy Tab 3 Lite. Amazon is even trying to tempt people to buy in bulk, offering them the chance to buy five and get a sixth tablet for free.

“Today, we’re taking another step in our mission to deliver premium products at non-premium prices,” said Jeff Bezos, Amazon founder and CEO. “The all-new Fire features a quad-core processor, is incredibly durable, and is backed by the Amazon content ecosystem, the new Amazon Underground and Amazon customer service with Mayday Screen Sharing. Fire sets a new bar for what customers should expect from a low-cost tablet.”

In terms of specs, the 7-inch tablet has a quad-core 1.3GHz processor, uses IPS screen technology, features front and rear cameras, and has a microSD card slot to allow users to add an extra 128 gigabytes of storage. The tablet will go on sale Sept. 30 and will come with the latest version of the Amazon Fire OS, which is a fork of Android and offers Amazon's own app, books and music stores as well as its Instant Prime video streaming service.

In addition to launching an all-new budget tablet, Amazon updated its 8-inch and 10-inch Fire Tablet range as well as its Fire Kids Edition tablet.

Following the launch of Apple's fourth-generation Apple TV last week, Amazon is also updating its own set-top box, with the new Fire TV, the headline feature being the addition of support for 4K video which will let users watch ultra-high-definition content from Netflix as well as Amazon's own Prime Instant video streaming service.

Finally, Amazon has also updated its Fire TV Stick, which has become the company's fastest-selling product ever, to add the ability to search for content and apps using the remote control. Both new Fire TV products are available to preorder now and will begin shipping in October.
