- 1). Find a tip that fits securely into your camera's power port. The tips come included with the adapter. Places like RadioShack sell the tips individually---they connect onto the end of the adapter's cable allowing you to adjust polarity. If a tip is too loose or you have to force it in, try another tip.
- 2). Check the polarity of the camera and the adapter tip. Near the power outlet on the camera you'll notice a small diagram with a plus sign on one side and a minus sign on the other. If the plus sign is on the left side of the diagram, the device is positive; if the minus sign is on the right, then the device is negative.
- 3). Check that the voltage of the AC adapter is the same as that of the camera. The camera's accepted adapter voltage, along with its amperage, must match or it will not work---and you could damage your camera.
- 4). Compare the amperage of the camera and the AC adapter. The amperage of the charger should meet or exceed the requirements of the camera---it is OK to go over on amps but not OK for volts.
- 5). Remove batteries from the camera, connect the power supply, then the camera. Power on the camera to test it.
