Outjut Hand Warmers Rechargeable 2 Pack (Black)

The Outjut Hand Warmers are a pair of rechargeable, portable heating devices designed to provide warmth to the hands in cold conditions. The product features a unique split snap-on design that allows the two individual hand warmers to be connected together for storage or used separately. Each unit is powered by a built-in 3000mAh rechargeable lithium-ion battery, which provides 8.5 to 20 hours of continuous heat on a single charge, requiring 4-5 hours to recharge via a USB cable. The hand warmers offer three adjustable temperature settings: a high setting of 118.5-130°F (48-55°C), a medium setting of 107.5-118.5°F (42-48°C), and a low setting of 95-107.5°F (35-42°C). Temperature and power level are indicated by LED lights. The device incorporates multiple safety certifications including UL, CE, and FCC, and features a smart protection system against overcharge, short circuit, and overload. Constructed with a flame-retardant and explosion-proof shell, it has a mech-inspired, technological design with a hard shape and smooth texture for comfortable handling. The product is suitable for outdoor activities such as skiing, camping, hiking, and fishing, or for daily use during winter commutes.
