It's a charger that is able to read (and balance...on more expensive models) the cells with in the battery pack and will shut off when charging is complete. It is also much faster and safer...
As opposed to a trickle/wall charger which is slow and dangerous as it does not stop charging... Especially dangerous with LiPo batteries...
