Mijia Cordless Straightening Brush: Xiaomi unveils a travel-friendly cordless hair dryer brush

Xiaomi has introduced the Mijia Cordless Straightening Brush, a compact and wireless hair dryer brush designed specifically for travelers. Combining portability, functionality, and safety, the device enables professional hair styling anywhere. Already available in China, its features make it an ideal companion for those who value a polished look on the go.

Key Features

The Mijia Cordless Straightening Brush stands out for its portable design and thoughtful functions:

• Weight: Just 269g, making it easy to carry in hand luggage or for daily use.
• Size: Compact form factor (approx. 206.5 × 44 × 43.5 mm, based on a similar model), easily fits into a handbag.
• Cordless Operation: Two 3200 mAh batteries provide 3–4 styling sessions (up to 4 for short/medium hair, around 3 for long hair).
• Charging: USB Type-C port; full charge in 3 hours with a 5V/3A adapter.
• Temperature Modes: Three settings — 160°C, 180°C, and 200°C — suited to different hair types (damaged, normal, or thick).
• Heating Technology: MCH ceramic heater ensures even heat distribution and emits up to 285 million negative ions/cm³ to reduce frizz and smoothen hair.
• Safety Features:
  • NTC Overheat Protection: Automatically shuts off after 30 minutes of continuous use.
  • Anti-burn Design: Plastic bristles and a thermal insulation frame prevent accidental burns.
  • Travel Mode: One-touch travel lock prevents accidental activation in luggage.
• Color: Elegant Cloud Purple.

How It Works

The brush features 6 ports for releasing negative ions that neutralize static electricity, making hair smooth and shiny. Ceramic-coated bristles minimize heat damage, and the three temperature modes help tailor styling to individual needs:

• 160°C: For fine, dyed, or damaged hair.
• 180°C: For normal hair.
• 200°C: For thick or coarse hair.

The device is powered on with a button, and indicators display battery level and selected temperature. After use, it shuts off automatically for added safety.

Price and Availability

• Price in China: 299 yuan (~$42 as of June 2025).
• Availability: Currently sold only in China via platforms like JD.com. No global release has been announced, but it may become available through international retailers such as AliExpress, potentially priced around $50–60.
