Complementing the batteries, the two included ultracompact chargers allow for a lot of flexibility. Each charger has a dedicated L-series battery plate and fold-out 2-prong U.S. plug. When the plug is folded in, the charger easily fits in most bag pockets. You can keep one charger at home and one in your bag or on the road. Supporting 90-240V worldwide power input, the chargers can be used internationally if you add the appropriate plug adapter, sold separately.
