46 useful products that might be more genius than Einstein

The world wide web is packed with some staggeringly inventive little gadgets, some of which are so clever, they just might be more genius than Einstein. Ok, perhaps that's a bit of an exaggeration (I can definitively say none of these products came up with the theory of relativity), but these useful products on Amazon are legitimately impressive nonetheless.

Some of these products are so simple and handy, that you'll wonder why no one's thought of them before. Case in point: charging cables designed to plug into phones and tablets at a right angle. This clever design hack prevents cords from fraying, and to make things even better, they're made from ultra-durable braided nylon that can stand up to lots of wear and tear.

And if you think these "genius" items will all be in the tech department, think again. There are intelligent finds to be had for every area of your life, like a universal lid that fits pots and pans of all sizes, so you don't have to spend time rummaging through cabinets while you meal prep, or a universal socket tool that automatically adjusts itself to be compatible with any nut, bolt, or screw you throw at it. Hey — with all these smart Amazon finds in your cart, it just might turn out that you're the Einstein in this shopping equation.

We only recommend products we love and that we think you will, too. We may receive a portion of sales from products purchased from this article, which was written by our Commerce team.
