Assuming your using a USB port to power your device, the answer is 2.5 Watts. A maximum of 500mA at 5V can be drawn from a Usb port. Power = Current * Voltage, which is 2.5 Watts by 0.5 Amps giving you a power output of 2.5 Watts

What does the electrical power dissipated in an appliance depend on?
The amount of power required to run an electric appliance depends on how many kilowatts of power it uses. The cost to run the appliance depends on how much your company charges per kilowatt. <<>> The amount of power depends on how much power it was designed to take. Some appliances are designed to take as little as possible, like radios, TVs and computers. Others are designed to turn electric power into another form of power, like mechanical power (motors) or heat power (space heating). These tend to use more power. The amount of energy paid for via the bill depends on the sum of the energy used by all the appliances. For each appliance it's the power drawn multiplied by the time it was used.
