Amazon has raised prices across several of its consumer hardware lines, including Echo smart speakers, Fire TV products, Kindle devices and eero mesh networking systems, according to Fortune as summarized by Techmeme and reported by The Verge. The company attributed the move to “significant increases in memory and storage component costs” in a statement given to Fortune, The Verge reports. The increases hit multiple categories of Amazon’s first-party device portfolio rather than a single product line. The Verge reports that some prices rose by up to 60 percent, with lower-priced products seeing some of the largest percentage increases. The Echo Dot smart speaker moved from $49.99 to $79.99. The Fire TV Stick 4K Max increased by more than 40 percent to $84.99, and the base Kindle now costs $149.99, a nearly 37 percent increase. The increases were not limited to entry-level devices. The Verge reports that Amazon’s Echo Dot Max smart speaker, which launched last year, is now priced at $119.99, up from $99.99. Not every Amazon hardware product appears to be affected. According to The Verge, Ring cameras and video doorbells and the Echo Studio, Amazon’s higher-end $219.99 smart speaker, are apparently outside this round of increases. Who benefits: Amazon may preserve more margin on devices affected by higher memory and storage costs. Existing owners are not directly affected unless they add or replace hardware. Who's exposed: Price-sensitive buyers are most exposed, especially on lower-cost Echo, Fire TV and Kindle products where The Verge reports the sharpest percentage moves.
