This viral ereader has come out of nowhere, and bookworms can’t get enough of it — but it ‘could ring alarm bells’ for Amazon as it surpasses the Kindle Colorsoft on the retailer’s charts

• The Xteink X4 ereader has gone viral for its compact size
• It's 4.3 inches, weighs under 80 grams and can be attached to Qi2-compatible smartphones
• It's the first non-Amazon ereader to make the top 10 list

Amazon has been the reigning champion of the best ereaders and its range of Kindle devices continue to dominate the market — but this viral mini ereader has taken social media and bookworms by storm.

The Xteink X4 is the latest gadget that users online can’t get enough of, and it’s all because of its compact size. Coming in at 4.3 inches and weighing 2.72 ounces (which is just under 78 grams), the Xteink X4 is small enough to fit comfortably in your pocket and can even be attached to Qi2-compatible smartphones such as newer iPhone models and Google Pixel phones.

Besides offering the features of a regularly-sized ereader but in compact form, its reasonable $70 price mark is another big selling point — a decent budget option compared to newer Kindle models which can be quite the investment. But following its popularity surge thanks to its online hype, it’s become a new rival for Amazon’s own ereader brand, and it could ring alarm bells for the retail juggernaut.

In a rare turn of events the Xteink X4 has ushered its way into Amazon’s top 10 best-selling ereaders, making it the first non-Amazon device to make the list. It currently sits in the number six spot, surpassing the Kindle Colorsoft and the Kindle Scribe Colorsoft, the former which still takes one of the top spots in our list of the best Kindles.

Despite the positives, reviews of its software have been a bit of a mixed bag as Trusted Reviews puts it, with some owners highlighting that its software offerings can be quite basic. But even then, this isn’t a massive setback that’s pushing away prospective owners, and it still offers an adequate casual reading experience, which could be even more of a threat to Kindle devices — especially given Amazon’s latest Kindle crackdown.

Just a few weeks ago Amazon announced it would be pulling the plug on older devices despite them still being used, which frustrated users believe is a way for the company to get you to needlessly upgrade to a new and thus pricier Kindle. The decision affects Kindle devices released in 2012 and before, meaning that as of May 20, you’ll no longer be able to purchase or download new books to your device, but you’ll still have access to read content that’s already downloaded.
