The GHJ 12+18V XA heated jacket is the perfect garment from Bosch to keep those who spend long hours on construction sites reliably warm. An ideal one-piece solution that keeps you warm despite harsh conditions and even with little movement, it eliminates the need to wear multiple garments on top of each other. The three-zone heating of this jacket ensures perfect heat distribution and keeps the upper body warm in all weather conditions. The three heat settings, powered by Bosch's 12 V rechargeable batteries, guarantee lasting warmth. For added convenience, USB-powered devices can be easily charged via the battery adapter's integrated port. The jacket's heating pads are powered by the GAA 12V-21 charging adapter and a Bosch 12-volt rechargeable battery (included), or optionally by the GAA 18V-24 charging adapter and Bosch 18-volt rechargeable battery (not included).
