This electric blanket is recommended for those who feel the cold, as it can be draped over your knees, shoulders, or feet, or used as a light blanket for a quick nap. It has a built-in heater and is a USB-powered electric blanket, suitable for use at home, in the car, at the office, or outdoors, allowing you to easily combat the cold anytime, anywhere. The temperature can be adjusted in three stages: low, medium, and high. By connecting it to a battery (sold separately), you can freely switch to a comfortable temperature according to your physical condition and how cold you feel, allowing you to spend even the coldest winter days warm and comfortable, making it ideal for those who are sensitive to the cold. It can be used comfortably when you want to relax at home or while working at your desk. The electric blanket is equipped with a three-stage timer function (60 minutes, 120 minutes, 180 minutes), and the power will automatically turn off when the set time is reached. You don't have to worry about forgetting to turn it off, and it won't overheat while you sleep, so you can rest easy even if you doze off. It's an energy-saving type that can save on electricity bills, making it suitable for use as personal heating to warm your surroundings. The internal heater releases heat to warm you up, and the ultra-fine fibers trap warm air, providing excellent insulation. Combined with the effect of a thick blanket, it becomes easier to maintain warmth, and your body will feel toasty. Easy to care for at home; when it gets dirty, remove the heater and cord, and you can wash the blanket itself, keeping it clean. It will be simply packaged by compression. Thank you. ☆
