arrying a standalone tablet-sized e-reader often feels redundant when a smartphone is already in your pocket. Device makers have spent years experimenting with ultraportable designs that mirror standard phone dimensions. The DuRoBo Krono tries to capitalize on that demand by combining an E Ink display with a full Android operating system in a pocketable build.
Smartphone feel and a hardware scroll dial
The main selling point of the DuRoBo Krono is how naturally it sits in the hand. As Digital Trends reviewer Nadeem Sarwar noted, the reader matches the iPhone 17 Pro in height and thickness, yet feels noticeably lighter than typical glass slabs. The chassis is crafted from matte plastic and features a horizontal metallic cylinder on the back.
This physical element is not just for show—it functions as a tactile scroll dial. On the software side, the device doubles as an AI voice recorder for memos and a minimalist audio player with battery life that traditional mobile screens cannot match.
Software quirks and hardware compromises
Despite the solid ergonomics, the software highlights the usual headaches of running full Android on electronic ink. The UI lacks fluidity: page refreshes occasionally lag, and navigating the interface takes some getting used to. Audio is another weak spot, as the built-in speaker produces flat, hollow sound, making headphones practically mandatory for listening to recordings.
Hardware omissions also stand out. The Krono lacks cellular connectivity and has no microSD slot. That places a strict ceiling on onboard storage and prevents downloading new books without Wi-Fi. Paying a premium for an e-reader tied to local networks with fixed storage makes it a tough sell compared to versatile mainstream gadgets.
At $280, the DuRoBo Krono costs as much as a capable midrange smartphone while remaining tethered to Wi-Fi and bogged down by E Ink latency. If you strictly want a featherweight pocket reader shaped like a phone, the form factor is appealing, but the steep price tag makes it a hard justify as a secondary screen for most buyers.
