This is especially useful in dusty or sweaty environments. * Industry-leading 15-month warranty: Choshin Japan backs the set with a 15-month warranty, providing peace of mind for daily professional use.

Connectivity & Compatibility

The set works with Choshin Japan's GB-POWER series and some third-party workwear; always confirm compatibility before purchase. The battery is a non-standard 30V type and is not interchangeable with 12V or 20V workwear systems.
