Bosch Smart System Charger

These chargers work with Smart System batteries only. The small and lightweight 2A charger is ideal for on-the-go charging – it's around 40 percent more compact than the 4A charger. It supplies the PowerTube 750 with the necessary energy in no time: It takes six hours to fully charge the battery, and just over two hours for 50% of a battery charge. The perfect opportunity for a restful break along the way.
