Better than my other chargers.

I like this one better than my other chargers. It's compatible with more types of batteries, has an LCD display, and has more advanced charging and protection features than most cheap chargers on the market. The price is actually very good for what it is.

Excellent charger.

Compatible with many types and sizes of batteries. Some chargers won't accommodate longer batteries -this one does. You get a varied choice of charging amperage with a detailed display of battery dynamics. It seems everyone in the world wants the fastest charging battery and device available, but this comes at the expense of battery longevity. You get a choice of 500mA or 1,000mA. I prefer a slower and steadier charge. Treat your batteries nice and they will serve you well.
