Renew Solar Battery Charger by Donn Koh

Let's preface this by saying that this is only a concept. However, ideas and designs like this can only remain concepts for so long before they're realized. The basic premise is this; when your rechargeable batteries are out of juice, simply drop the battery into the top, and when it's ready it'll be ready for plucking at the bottom. It theory it will charge multiple batteries at once. The best part, it uses the solar panel on the back to do it, so your charging is completely off the grid. You can opt to hang the charge station on a window, or prop out the solar panel as a kick stand of sort and rest where it'll receive plenty of light. The beautiful felt outer skin is just design gravy on an already ingenious device. More pics after the jump.
