Have one. Found out the following:

1. Old 25" crt tv uses 10 watts in standby and 80 watts on.
2. Newer 36" crt uses 1 watt standby and 80 watts on.
3. Samsung ML1640 printer not printing 2 to 350 watts. Wattage suddenly jumps. Dont know why. I just turn it off now when not printing. Have not measured wattage while printing.
4. Almost same wattage for steel blade stand fan and plastic blade desk fan.
5. 35 watts for laptop.
6. 2 watts for sony cell phone charger.
7. 1200 to 1300 watts for microwave oven.
8. Ref 20 watts for light and around 175 watts for compressor.

Is there an plug adaptor so I can test my aircon units?
