The Nitecore i8 Intelligent Charger is one of the best multi-slot chargers available.

What makes the i8 so remarkable is, its Active Current Distribution (ACD) technology which distributes power among its 8 slots in an orderly manner and allows the unit to monitor and charge 8 battery slots independently and boosts the recharge speed up to a blazing fast 1500mA per slot.

The unit also boasts intelligent design with the inclusion of two USB output ports which allows the option to charge devices like smartphones and tablets, saving you room on your desktop. The i8 also features easy to view red and green indicators which gives you the added bonus of being able to view the current charging status of your batteries from across the room.
