Smart Self-Cooling & Heating Tumbler

Say goodbye to warm drinks on hot days. This isn't your average insulated cup — it actively cools your drink down using a built-in semiconductor cooling chip, so every sip stays refreshingly cold no matter where you are.

Hot or Cold, You Choose
A wide temperature range of -5°C to 55°C (23°F to 131°F) means it works just as well for hot coffee on a winter morning as it does for ice-cold water on a summer afternoon. One cup, two modes, zero compromises.

Semiconductor Cooling Technology
Powered by an ETC semiconductor cooling chip — the same tech used in precision electronics. It cools fast, runs quietly, uses minimal energy, and stays compact enough to take anywhere. No ice needed, ever.

Built to Last, Built to Trust
The inner lining is SUS316 food-grade stainless steel — a higher grade than most tumblers on the market — so your drink stays pure, clean, and free of metallic taste.
