What can be better than a cup of hot herbal tea in a cold autumn day? Unfortunately not all thermos bottles can hold hot temperatures in harsh northern climate. The Ember Temperature Control Smart Mug not only looks good but also has lithium-ion battery technology to warm up you drink in a few seconds. The outer surface of the cup is not heated, hand will feel comfortable anyway. You can control a cup with your smartphone – the app will show how hot you drink is. The cups are available in white and black colors and can be a good present.
