Amazon has unveiled a new version of its Oasis Kindle flagship e-reader, complete with an adjustable “warm light” to make it easier to read in changing light conditions.

The technology giant’s newest reading device will come with a seven-inch screen and is waterproof.

Amazon says the Paperwhite display on the new device “reads like printed paper” and is their best ever screen on a Kindle. The flagship e-reader in Amazon’s line-up, the Oasis will cost US$250 (R3 600 before duties and other taxes), and will go on sale on 24 July.

The device was unveiled alongside new research from Kelton Global which suggests that more than half of people in the UK (56%) say their favourite holiday activity is reading.

Eric Saarnio, Amazon’s head of devices in Europe said the new adjustable screen light would help to make the Oasis a more versatile device.

“The all-new Kindle Oasis includes everything customers loved from the previous generation, including the large 7-inch display, waterproofing and Audible — and now we’re making it even better. We’re adding an adjustable warm light so customers can read with a warmer tone that’s customisable to their preference to easily transition from daytime to nighttime reading,” he said.

“Kindle is designed to create a sanctuary reading experience, and the all-new Kindle Oasis exemplifies this — whether you’re reading poolside on holiday or in the comfort of your bed.”
