Portable Heated Shawl: These 12V heating blankets are perfect for various settings—whether in the office, at home, commuting, traveling by car, camping, visiting exhibitions, hospitals, or watching games. Its spacious size of 43x59 inch allows it to double as a comfortable blanket for relaxation anytime, anywhere. Don't worry about stains; it's machine washable (just remove the portable charger first). For longer durability, we recommend hand washing to keep your shawl looking and feeling new while providing consistent warmth,Featuring multiple power supply options for your convenience! This product does not come with a power bank, allowing you to use your own 5V/2A power bank, which can save you money. If you need a new one, you can easily purchase a compatible 5V/2A power bank separately, making it a more cost-effective choice than buying a heated blanket bundled with a battery!
