Amazon raises prices overnight on several hardware lines, including Echo smart speakers, Fire TV streaming devices, Kindle e-readers, and eero routers, with increases of up to 60%. The company says the changes are driven by “significant increases” in memory and storage component costs, according to a statement provided to Fortune.

Outlets report that some of the steepest jumps land on lower-priced models. For example, the Echo Dot price increases from $49.99 to $79.99, while other products in the Echo, Fire TV, Kindle, and eero ranges also move upward. The Verge describes the hikes as broad-based across Amazon’s smart home and media hardware categories, while Fortune frames the timing as a quiet, overnight adjustment.

The reporting also places Amazon’s move in the context of wider tech-industry pricing actions. Fortune notes similar steps by other major technology companies, including Apple, Dell, and the Xbox console business, suggesting component cost pressures are affecting multiple product lines.
