The Nitecore D2 is a simple to use, dual-slot battery charger with an LCD screen that displays key information.

Compatible with a wide range of e-cigarette batteries, including 18650, 20700, 21700 and 22650 versions, and most circular cell batteries such as AA and AAA batteries.

A compact design that is simple to use. The Nitecore D2 has an intelligent auto-detect function that identifies the type of battery installed and selects the appropriate charging voltage and current. When one or two batteries are charged, each charging slot will receive a max output current of 0.5A.

Different types of rechargeable batteries may be charged simultaneously using either 1 or 2 of the charging slots. When a battery is first inserted, the charger will test the battery and the LCD display will illuminate. Once this quick self-test is complete, the name of the product will appear on the screen and the charger will enter into charging mode. If any unusual circumstances are detected, the LCD will display an error message “Err”.

While in charging mode, the battery indicator bars will blink rhythmically to indicate the ongoing charging process. The battery’s power status and charging process are indicated by the number of bars that illuminate. The LCD will also display battery voltage, followed by charging current and elapsed time. Pressing the “MODE” button will cycle through these charging parameters. To view the charging progress of a different charging slot, press the “SLOT” button. When a battery is fully charged, the battery indicator will illuminate steadily and the screen will display “Chg.Finish”.
