The Nitecore Q4 fast charger has four separate charging slots and has been designed specifically for IMR batteries. The Nitecore Q4 charges up to four Li-ion batteries simultaneously at up to 1000 mA in each slot, with a maximum output of 2000 mA.

The Q4 features an optimised IMR charging technology that can monitor the whole charging process, ensuring the end voltage is always within safe limits, hence extending battery life. Active current distribution (ACD) technology enables the Q4 to evenly distribute all of its power throughout its four slots.
