Does the charger automatically shut off when the battery is fully charged or does it continue to draw power?
Junhao Lo –
Thank you for your question, Ryan! We’re happy to clarify that the Nitecore i4 Charger does indeed have an automatic shut-off feature. The charger will automatically turn off when the battery is fully charged to prevent overcharging and reduce energy waste. This feature is a great safety precaution and energy-saving benefit. Please note that this feature only works when the charger is connected to the batteries and not when it’s left with no charging activity for an extended period of time.

While this charger is an excellent product in many ways, there is one major drawback that prevents me from giving it a full 5-star rating. The LCD display can be quite finicky at times and may require multiple button presses to cycle through the different screens.
