Smart Charger Lithium Ion 

  • Ideal For Travel: Auto-ranging input allows the charger to work in any country whose electrical system falls within a 100V - 240V range. AC adapters for the following regions are available: USA, Europe, United Kingdom, and Australia.
  • Conditions Cells: The charger showcases the latest pulse charge technology; this feature grants near complete charging while also conditioning cells over time, resulting in longer battery life and more flashes per charge. Its "trickle" charge mode helps maintain a pack's charge without danger of overheating. In addition, this charger is less likely to fail when used with poorly regulated power sources.
