Nobody enjoys drinking coffee or tea that is not warm enough. The LAVACLIP Coffee Warmer is a handy tool that lets you keep your latte and coffee at the proper drinking temperature. It can be used to warm paper cups and mugs.
This gadget attaches to the bottom of your cup and keeps it warm on the go. It can be charged using a micro-USB connection. Like what you see? You can find this project on Kickstarter.
