【Electric Blanket with USB Extension Cord】Size: 160*80cm, Weight: 0.8kg, USB-powered electric blanket. Not only protects your knees, but can also be draped over your shoulders. Covers cold feet. Perfect for winter camping, camping, cars, homes, offices, etc. You can drape it over your shoulders, cover your feet, lay it on the bed, or use it as a blanket. In the dry winter months, static electricity is likely to occur, so it is recommended to use the blanket in conjunction with a humidifier. The included 1.5-meter USB extension cord can be connected directly to the USB port of your computer when used in the office. 【Skin-Friendly Velour Material & Washable】Heated shoulder wrap. This product, which uses carbon fiber heaters, is thicker than other products, so it heats up quickly and maintains heat retention. It is also safe and durable, so you can use it with peace of mind. It has a smooth, velour-like texture, providing a comfortable warmth. ★Washing Instructions: ・Hand washing is recommended. Before washing, be sure to remove the USB cable and battery, and attach the waterproof cap to the storage pocket. ・Wash with the pocket zipper completely closed. 【3-Level Temperature Adjustment】USB electric blanket. When the power is first connected, the power lamp on the switch lights up for 1 second and then turns off. Press and hold the switch until the lamp lights up (the initial setting is 60°C, the highest temperature). The temperature settings are divided into 3 levels (high 60°C, medium 50°C, low 40°C), and you can cycle through high → medium → low → high by short pressing. When finished using, press and hold the switch for 3 seconds for safety, and keep the operation until the lamp is completely off. ※Note: Battery sold separately. 【Suitable for Various Scenes】Standard 1.5m USB cable is included for convenience, so you can use it anytime, anywhere, such as taking a nap in the office, sleeping in a car, camping, fishing, watching baseball games, etc. 【Improved Heat Retention with New Material】This electric blanket for both men and women uses skin-friendly flannel fabric to achieve a fluffy, enveloping feel and uniform warmth. The built-in new material "insulating aluminum sheet" highly reflects the heat of the heating element (reflectivity of 95% or more) and blocks external cold air, extending the heat retention time by up to 30% (compared to manufacturer's tests). It is a PSE-compliant product, so it provides safe and efficient heat retention. I have opened it, but it is new and unused. Immediate purchase is welcome!
