If you have ever wished there was a device in existence that could keep condensation rings off your table and also powered up your smartphone, you are in luck because someone just invented a phone-charing drink coaster. Currently in the midst of a crowdfunding campaign on Kickstarter, Circle by ChefCharger is an MIT-designed bamboo coaster that allows you to "sip your drink and charge your smartphone in style."
Elegant and functional, the wooden circular phone-charging drink coaster easily blends into its environment. The convenient and portable creation does away with unsightly wires, is sustainably made and is waterproof, so you can be sure to use it safely. It has also been tested and recharges your phone in 2 hours.
