The GNARBOX lets you backup and upload 128GB of footage from your camera and edit that footage on a smartphone or tablet via their app. Insert a memory card—MicroSD or SD—or connect the GNARBOX to your camera using a USB cable. Once you've transferred the footage, connect your tablet or phone to GNARBOX's built-in WiFi, open the app, and start editing your footage. It works with RAW and 4k videos. Once you're done editing, you can send the videos to friends over social media, upload the footage to your computer, or plug in another hard drive to back up that footage. The device is shockproof and has a 4000mAh battery, which can be used for four to six hours of editing. $300.
