One of the drawbacks of Apple mobile devices, many users find the inability to extend the built-in storage with a memory card. To solve this problem will help accessory called the Dash-i, which debuted on Kickstarter. The device has a metal housing and is a conventional card reader that connects to an iPhone or iPad via the connector Lightning. With the help of iOS-devices owners can use them with microSD memory cards up to 200 GB.
Dash-i also allows you to transfer any data from the device to the memory card and vice versa. Additionally, through a special application to music, photos, movies and other files can be opened directly from a memory card without transferring them to your smartphone or tablet. This can be useful on the road, to record on a memory card movies or music, leaving the smartphone space for photos.
It's also used for transfer file from iphone to ipad.
Developers offer regular version Dash-i, which has only slot for the memory card, as well as model Dash-i Plus, allowing at the same time using an accessory to carry out mobile device charging.
