Instant Warmth USB Neck Scarf

Custom Comfort: The 3-Gear USB Electric Heating Scarf

Experience targeted, customizable warmth with this innovative USB Electric Heating Scarf. Designed for outdoor winter activities, camping, and everyday use, this scarf combines high-quality materials with convenient, adjustable heat to keep you warm wherever you go.

Advanced Features & Specifications:

• Premium Materials: Crafted from a blend of Fleece, Cotton, and Acrylic, the scarf features a delicate, high-quality mink fleece feel. It's warm, breathable, and exceptionally skin-friendly for all-day comfort.
• 3-Gear Precision Temperature Control: Easily adjust the heat level to match the weather. A single button allows you to cycle through three settings:
• Red Light: High Temperature ($55^\circ\text{C}$)
• Blue Light: Medium Temperature ($48^\circ\text{C}$)
• Green Light: Low Temperature ($42^\circ\text{C}$)
• Washable & Durable: Designed to be directly washed without disassembly (like an ordinary scarf). It offers a certain degree of waterproofing and is evenly heated. (Note: Do not soak in water for a long time, as prolonged immersion may affect adhesion.)
• Lightweight & Portable: Convenient to carry and wear, making it an essential accessory for winter camping, hiking, or for anyone who suffers from the cold.
• Easy USB Power: Simply connect the 5V/2A USB cable (rated power 8W) to a computer, power adapter, or a mobile power bank for instant heat.
