Aaron Krause is the founder of Scrub Daddy, the yellow circular smiley-faced scratch-free sponge that adjusts with water temperature — hard for cold, soft for hot. He made a deal with QVC Queen Lori Greiner on Shark Tank, and today, Scrub Daddy is the most successful product in Shark Tank history. Krause has gone on to expand the Scrub Daddy line with Scrub Daddy Heavy Duty, Big Daddy, and Jumbo Blocks, among others.

Now Krause is working on a new invention, The Ion Belt. With British inventor Piers Ridyard (creator of the Nifty MiniDrive), Krause has launched a Kickstarter campaign to finance the production of a belt that can charge your phone while you’re wearing it. The Ion Belt comes with a USB recharger in the buckle pin, and an LED charge indicator on the strap, so you know how much power is left. The Ion Belt is available for $79 and will be delivered in June 2016. [Related: 27 Favorite ‘Shark Tank’ Products at Amazon — New List]
