Kill A Watt
Measure the power consumption of the device you want to pedal power. Connect it to the wall, then connect your device(s) to it, and read the Wattage number.
You can read the writing on the product OR you can actually measure it using a device like the Kill A Watt. The second way is better for two reasons: It’s more educational and fun, and some product ratings are approximate. Some products use different amounts of power at different settings. For example, a loudspeaker will use way less power than its rating if you’re listening to music at moderate levels. So get yourself a Kill A Watt and get scientific!
