The Nitecore UNK1 is a USB battery charger designed exclusively for Nikon cameras and is compatible with a range of models. Offering dual slots on the front and back of the charger, the UNK1 caters for both the primary and back up batteries, ensuring you have power when you need it most. The charger features a smart charging management system, monitoring battery types, capacities, internal resistance upon charging initiation and automatically applies the most appropriate charging current based on the monitored data.
