Thanks to Bluetooth.

A mug that can adjust the temperature of your coffee or tea is just one of the quirky gadgets that surfaced at this year’s CES. Designed by American company, Ember Technologies, the battery powered coffee cup has a dial that users turn to set their ideal coffee temperature. The coffee or tea will remain at the set temperature for two hours if on the go, or all day when used with its charging coaster.

Bluetooth capability also enables users to pair the cup to their smartphone to set temperatures, name their cup, choose and save presets for different drinks and switch between Celsius and Fahrenheit. The cup also has a leak-proof push to open lid, contoured shoulder for easy grip, rotating ring for temperature adjustment among other features.

The Ember cup is available in the US at Starbucks or can be ordered online and shipped to Australia.
