The BCN-1 is the dedicated lithium-ion battery charger for the BLN-1. Charging time is around 3 hours. It's always handy to have a second charger for use at work, or on vacation. Item number: V621035XU000 Note: The charger's input voltage will automatically regulate between 100V-240V~50/60Hz. For overseas use, we recommend only a plug adapter for the country you will be visiting. Plug adapters are usually sold at stores that feature travel items such as luggage.
