||This thing has saved so many of my batteries from being over-charged. There is a light on the charger that is red when the battery is charging and goes green when the battery is done. It also stops charging when the battery is at it's peak charge, therefore not overcharging and destroying your battery. For $30, it couldn't get any better.
Lights change when charging and when fully charged
Stops charging at the battery's peak charge
Charges a fully drained battery in 30-60 minutes, instead of a trickle charger that takes 6 hours
You can forget about it when it charges with no worry of the battery being overcharged
Comes with a large to small connector so it can charge small and large type batteries
Cannot charge LiPo batteries or LiFe batteries
All in all, this thing is amazing for non-LiPo batteries. Definitely a must have for every airsoft player.
