The Canon CB-2LV Battery Charger is exactly what the name implies: a device which charges batteries. Of course, it doesn’t charge just any batteries! This charger is specifically for use with one of two battery packs (your choice): the Battery Pack NB-3L and NB-4L. These batteries belong to the Canon Powershot SD200, SD300, and SD400 cameras. So, if you have one of these cameras (and therefore one of the compatible battery packs), this charger is the way to go.

It takes about 95 minutes to charge a battery completely using the Canon CB-2LV Battery Charger. The batteries do tend to hold their charge fairly well, so you can charge your batteries at night for use during the day and not lose any photography time waiting for them to charge.

One notable feature about the Canon CB-2LV Battery Charger is that it has a plug with an extension cord. The travel version of this charger, which comes with the purchase of a Powershot SD200, 300, or 400 camera, has a fold-out plug directly in the back which many people find more convenient. The travel version is about ten dollars more than this model, and differs only in the plug, which does not make it any more or less effective – so it doesn’t particularly matter which one you buy.

Charging batteries is a very exciting process which makes certain types of batteries reusable. This is convenient because it means fewer batteries in landfills and it’s just overall better for the environment. You should use rechargeable batteries whenever you can, because they’re awesome. Therefore, the Canon CB-2LV Charger is awesome by association. Ultimately, you’ll be a better, cooler person if you purchase this charger.

If you need to charge your Battery Pack NB-3L or NB-4L, and you don’t mind having an extension cord attached to the charger, you’d be silly not to get the Canon CB-2LV Battery Charger.
