A:AnswerFirst, confirm the voltage needed by your camera matches one of the output voltages of this device. Next look for an image molded or stamped into your camera near the input jack or in the documentation that shows the center pin needed by your camera is positive (+) while the outside jacket of the plug is negative (-). Reversing the polarity or using too high a voltage will damage your camera.
A:AnswerConverts 120V AC to 3-12V DC with 1300 mA maximum output
So you can easily switch for devices requiring 3V, 4.5V, 6V, 7.5V, 9V or 12V DC output.
The amperage is not selectable. However, typically these types of devices usually do not provide a selector switch for amperage - only voltage. This device can deliver up to 1200 mA. If a device only requires 300 mA the converter does not push more than the device requires. A 300 mA requirement is within the maximum potential of the 1200 mA rated converter and can be used to supply the 300 mA necessary to run the device without causing damage to the device.
A:AnswerI doubt it. If your unit needs 2.5A (2.5 amps of current at 12 volts) then this unit would likely overheat and not last long as it only has 800ma of power or .8A.
