When I received the package I thought: Great finally finished leaving the gopro connected to recharge and 2 extra batteries avoid me from falling stranded in the middle of the day if I forget to recharge une.De more that comes with a cigarette lighter charger so it can be used even in voiture.Mais because yes there is a but, the load takes a long time for an empty battery from empty you will take between 5 to 6 hours to charge fully and charger takes a lot of space in her bag.
