The Inkcase Plus is a secondary screen for your Android smartphone. It pairs up to your device using Bluetooth and once you install the e-reading app, it functions as a mini e-reader.
This device features a 3.5 inch, 360 x 600 pixel e-Ink display which is visible in direct sunlight. The low-power screen also only uses electricity when you refresh the page, so it should get up to 10 to 15 days of battery life.
There are a number of apps available for the Inkcase Plus, such as a photo gallery, sports and picture app. My personal favorite is the e-reader app, you can simply load in your own e-Pub books and turn it into a dedicated 3.5 inch digital reader.
