 J. K. Medico markets two series of new marine chargers:


The HANDY and the FIX charger family covers the entire range from small to large batteries, 40-300 Ah. The HANDY chargers are portable and are typically used for open sailing and motor boats, where the FIX chargers are designed for fixed installation and use in all maritime applications. Both charger types are used where a safe and fast charging is required, with a minimum of energy loss. A computer controlled charging process ensures the possibility of adaptation to different battery types. A patented energy transfer ensures high efficiency, while TCS (JK Medico's patented charging method) ensures an optimal treatment of batteries. 

The key characteristics of the HANDY and FIX series are the same:
