The ACK-DC70 AC Adapter for Select PowerShot Cameras from Canon lets you circumvent the battery and power your camera straight from an AC outlet. This adapter is ideal when you're using the camera for extended periods in an indoor location such as when doing studio work, when uploading images to your computer, or when playing back files on your TV or recorder. With a 100-240V input this adapter can be used in the US and abroad (with appropriate plug adapter).
