The X2 card has 8GB memory which allows for storage of up to 4000 photos (JPEG format) or 3 hours of video. After upload you can free-up space which means the card will never run out of space. This Eye-Fi Mobile X2 card also features a Direct Mode. This means that even when out of WiFi range, the card can still send JPEG photos and videos directly to your iPhone, iPad or Android device. Backing up photos is made simpler by wirelessly uploading photos and videos to specific folders on your PC, or to iPhotos on your Mac. Sharing precious moments and memories with friends and family is possible by sending photos and videos straight to popular social networking sites. This Mobile X2 card is very similar to the Eye-Fi Connect X2 but has double the storage capacity. It also carries many of the features of the Pro X2 but doesn't have Geotagging or Hot Spot access as standard. Both of these features can be upgraded onto the Mobile X2.
