In year 2010, some electrical powertool engineers came out the idea and succeeded in combining the most advanced powertool Li-ion battery technology with aerospace garment heating system. Their original idea was to provide protection to outdoor workers, but after 5 years development, BSA-HEAT system has become the popular choice for Europe and USA outdoor workers and sporters. Each year, tens of thousands of BSA-HEAT system were sold globally.
Valtage: 12V Capacity: 7800Mah Li-ion Cells: ICRI8650-26F Input: 100-240V 50/60Hz Output: 12.9V 1.0A Charge Time: 3 Hours 2-Color LED Display: Red-in charges; Green Full or Standby Plug Style: SAA Plug With Fully Protection Ergoncncmic Design 
Waterproof heating system makes the garment water washable. 8 or 12 voltage direct current, less than 1 Hz working frequency, no radiation at all.
