The Leica compact charger unit is designed with space in mind. It takes up very little move, perfect when space is everything. It as a quick-charging function. The LED flashes yellow after about two hours when 80 percent of the charging capacity has been reached. 80% is is enough for about 400 exposures, a fully charged battery gives you about 500 exposures. The battery can be charged and used at any stage. The charger comes complete with UK, EU and USA power cords as well as car charging cable for 12-24 Volts are included.
