How does it work?

Plug the Power Angel on the wall socket is one way; or for ease of testing I use an extension cord so that I could take pictures of the result.

If you are plugging in several electrical devices onto a single household outlet rated at 15 amp (115 volt in my case), make sure you don't plug in more than it is rated. The Power Angel will do a nice job in letting you know.



Using my heat gun to warm up my coffee looks cool, but it will cost me. The best way is to use my coffee maker. Leaving my computer running while I am not around or out of town is like leaving a 120 Watts light bulb on. Perhaps, this device will tell my girl friend not to plug her PC into the same socket circuit that is taken by the Microwave oven instead of me. My brother has four systems running 24/7 would be like turning on the microwave oven three months out of a year.

Although all the functions are nice, the most important function of the Power Angel is the Power Factor which allows the user to know the power efficiency of a device. When Input equals Output is what we dream of other than nuclear power, better than 80% efficiency in a power supply belongs only to a few.



The above shows the efficiency factor of the power supply in use is 69% at idle state, and it improves to 73% at higher load.



"It's 10:51, may I borrow your Power Angel for the day?" my brother asked. I placed an order and purchased one for him. :)

Conclusion :

Power Angel is a nifty product. It allows the user to ID the power requirement in a handy package. For about $34, it is a nice tool to have around whether you are a house, boat or RV owner. It is a PC hardware reviewer's best friend. Lastly, a multi-meter with leads plugging into the socket to test for voltage is not for everyone.


Pros:

Functional product for its intended purpose

Handy package

Inexpensive

Simple to use

Cons:

None

How about using those "folded up" plugs (legs) to make it easier for "on the go" users? I like to thank Celia for sending me this wonderful product for review.
