There are a growing number of eReaders with color E Ink displays. It’s an Android-powered device with the kind of specs you’d expect to find in an entry-level tablet. There’s a built-in 1200 mAh battery in the tablet itself, and a 1950 mAh battery in the cover. But the MoaanFLY has a higher-performance processor than most eReaders and E Ink tablets, while the tablet section itself has a relatively small battery. The MooanFLY measures 154.3 x 136.3 x 3.9mm (6.1″ x 5.4″ x 0.15″) at its thinnest point and 7.7mm (0.3″) at its thickest.
