Yecup is an app-controlled, temperature adjustable wireless mug. This means that you can take it with you absolutely anywhere you go; to the gym, to any public places, at college or in the park! In case you don't have charging, Yecup also charges smartphones and tablets up to 3 times a day and is charged itself in 3 optional ways; wireless, with USB charging and AC adapter for fast charge. The easiest app cools and heats up your beverage on the go and sends notification as soon as your drink is ready! Yecup glows in red/blue colors referring to a certain water condition; hot/cold. Green light switches on when the mug takes charging.
