i've bought the unit from you during the weekend. I'm not so much into all this power equation and etc... Just wondering if you could enlighten me on things i'm not sure.

i've measure a few stuff in my house as below :-

Air Cond - reading about 980 WATT during operation, 5.6Kwh , total on time 6 .29, and i've set price 1 at RM0.22 so it shows 1.24 for total price.

Q1. Does it means 980 WATT = 0.980 kW/h?
Q2. Does 5.6Kwh = 5.6kW/h?

My Dell laptop adapter stated to be 90W-AC Adapter, Input AC 100-240V~1.5A, Output DC 19.5V 4.62A

The meter reading VOLtac 244, 0.14 AMP, 33 WATT(average)

Q3. I don't quite understand the meter reading vs the adapter stated value. I wonder if the meter is reading accurately?

Q1. Correct if you see this during operation. Per hour.

Q2. No. It is 5.6kWh. This is cumulative consumption since you started measuring. Typically avg WATT x Duration (hr) will give you this.

Q3. Laptop adaptor typically shows max output capability. 90W (19.5x4.62) is the maximum output the adaptor supports. Based on formula Power (W) = Volt (V) x Current (A).

When you plugin your laptop and measure, it shows 33Watt is normal usage. My laptop also shows 30+watt average. If You play some games on it or do some number crunching and it will go up. if you show a blank white screen at max brightness and WATT will go up. When you turn off screen or go on suspend, it will drop.

Hope this explains. Do let me know if you have any further questions.

Hi, item received. Thanks for fast delivery!

Very interesting item. My 1.5hp aircon is sucking about 1kW when just turned on, which is about expected.

I bought the power meter from him and finally I can get to know my power consumption, energy efficient or not by monitoring the power factor and get to know how much the devices consume when on standby.

The accuracy seemed to work as promising, but so far I can only verify the only voltage reading using my own multimeter, but the wattage reading also quite promising.

The Kwh feature is a must need to let some other understand that I did not bump up RM50+ of their electricity bill when borrowing thier wall plug for 30mins of using the compressor pump rated at 1800W! mad.gif
