Xiaomi KKF Vacuum Bottle 24H Insulation Stainless Steel Flask 475ML

The Xiaomi KKF Vacuum Bottle is a sleek, durable thermos designed for people who refuse to compromise temperature, flavor, or convenience. With a 475 ml capacity, it offers a compact yet generous serving size that suits office desks, gym bags, and travel rucksacks alike. This is more than a bottle—it's a versatile travel cup that doubles as a sport mug, ready to keep your beverages just the way you like them.

Key features that set it apart

• 24-hour insulation — double-wall vacuum construction minimizes heat transfer so your drinks stay hot or cold for up to a full day.
• Stainless steel integrity — durable, corrosion-resistant 475 ml flask that endures daily use without flavor transfer or staining.
• Portable design — compact, easy-to-hold form factor that fits into bags and stands up for on-the-go hydration during commutes, workouts, and outdoor activities.
• OLED temperature display — convenient at-a-glance readout on the lid to monitor beverage temperature without guessing.
• Versatile hydration solution — functions as a travel cup and sport mug, so you can sip comfortably whether you’re at home, in the office, or on the trail.

Who is it for?

Ideal for students, professionals, athletes, travelers, and outdoor enthusiasts who value reliable temperature retention in a compact, stylish flask. If you want a single bottle that can switch from hot coffee in the morning to cold water after a workout, this KKF model is designed for you.

How this compares to everyday flasks

While ordinary mugs and generic bottles can lose heat quickly or require you to juggle multiple containers, the Xiaomi KKF vacuum bottle leverages vacuum insulation to maintain the right temperature longer and with minimal bulk. The built-in OLED temperature display adds a practical edge, letting you plan your beverage intake without opening the cap. And at 475 ml, it delivers a satisfying serving size without weighing you down.

Practical tips for best results

• Before first use, rinse with hot water to prime insulation.
• Fill to the top to minimize air space for better temperature retention.
• Keep the lid closed when not drinking to preserve temperature and prevent spills.
