Say Goodbye to Scalding Hot and Lukewarm Tea:
Coolinno Phase Change Temperature-Regulating Mug Redefines Your Drinking Experience

Have you ever experienced this awkward moment? Freshly brewed hot water is too scalding to drink, so you set it aside to cool. But when you finally get back to it after being busy, the water has gone completely cold and tastes flat. A cup of water—either too hot or too cold. Getting it just right always seems to depend on luck.

Now, there's a brand-new solution: the Coolinno Thermal Storage Temperature-Regulating Mug.

Coolinno's Innovation: Putting Technology Inside a Mug

After extensive experimentation and formulation optimization, Coolinno's R&D team has successfully integrated food-grade phase change materials safely and stably into a double-wall mug body structure.

Core Advantages

Cools Quickly Without Scalding: After pouring in boiling water, it reaches a drinkable temperature in about 3 minutes—no more long waits or risk of burning your mouth.

Long-Lasting Warmth, Not Lukewarm: At room temperature (approx. 25°C), it maintains water within the comfortable drinking range for over 4 hours—far superior to ordinary vacuum flasks.

Healthy and Safe: All materials in contact with liquids are certified for food contact safety. The PCM medium is non-toxic, odorless, and non-migrating.

Eco-Friendly and Durable: The PCM can be used tens of thousands of times without performance degradation. One mug will accompany you for many years.

Who Is It For?

Busy office workers: Brew coffee or tea before a meeting; come back to find it still pleasantly warm.

Households with elderly or children: Completely eliminates the risk of accidental scalding from excessively hot water.

Outdoor and travel enthusiasts: On long train rides or road trips, always have water at the perfect temperature.

Anyone who values quality of life: Every sip is at the ideal temperature, making even drinking water a more enjoyable experience.

More Than Function – Thoughtful Design

The Coolinno Temperature-Regulating Mug features a 316 stainless steel inner liner and a matte-finished body that is slip-resistant, durable, and comfortable to hold. The lid includes a built-in silicone sealing ring and a 360° leak-proof design. Its simple, modern look fits any setting—office desk, coffee shop, or home dining table.

What Users Are Saying

"Before, when preparing formula for my child, I always had to mix hot and cold water to get the right temperature. Now I just pour hot water directly into the Coolinno mug, and in two minutes it's perfect for drinking. So worry-free!"
— Ms. Li, Hangzhou

"As a coffee lover, this mug is a lifesaver. My Americano is no longer too sour to drink right after brewing, and my latte doesn't turn cold halfway through."
— Mr. Chen, Shanghai

Get the Temperature Just Right, Live Life More Comfortably

Coolinno believes that true technological innovation isn't about creating complexity—it's about making daily life simpler and more comfortable. A mug might seem like a small thing, but every time you lift it and take a sip at that perfect temperature, that sense of certain satisfaction is exactly what good design is all about.
