It is great to have a car charger and two extra batteries for my canon camera. It comes in handy going to my kids high school sporting events. Always having charged batteries and a way to charge them going from one game to the next!! It is a great investment at a great price.
I love all the optical zoom I get from my Canon Power Shot SD4500IS, but if you play with it a lot it does eat the battery charge. The replacement NB-9L batteries in this package appear to hold their charge the same as a genuine Canon battery. Considering that I got two batteries, along with a charger that can be used both in the car & at home - I feel I got good value.
