This is the pocket-sized device that plugs into a smartphone’s or tablet‘s charging port and automatically backs up photos using a free app. The easy-to-use data vault works like a flash drive and copies JPEGs, TIFFs, PNGs, BMPs, GIFs, and more without password set-up or a subscription fee. It automatically skips duplicates and requires no Internet connection. Its built-in USB interface plugs into a PC/Mac USB port for transfer when preferred. Works with iOS 8 and up, Android OTG (version 4.1) and up, Windows 10, 8, 7, Vista, and XP, and Mac OS 10.7 and above. 32 GB capacity (about 16,000 photos).
