Nitecore UNK1 Charger for Nikon EN-EL15 (A) + EN-EL14 (A)

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, slot 1 is compatible with the EN-EL15 battery and slot 2 with the EN-EL14 or EN-EL14a battery. Please note, the slots are compatible with different batteries and cannot charge two of the same cells simultaneously.

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. 

The UNK1 has an LCD display screen which provide feeds on overall charging status, including the charging current, battery voltage and battery level. In addition, the charger monitors the condition of the battery based on the internal resistance upon installation. This is displayed via a BH (battery health) bar which is divided in 3 segments. When a battery has reached its lower health limit, the BH bar will start flashing to indicate the battery should be replaced.
