Power Cables - extension, cables


This product is fine if you are just using it to free up space on your surge protector or UPS that would otherwise be used by A/C adapters for cell phones, speakers, etc.



However, this cord is only rated for 10 amps. Unfortunately that is not disclosed anywhere in the promotional materials. This means you can only use it for electrical loads of up to 10x125 volts = 1,250 watts. So if you were intending to use this with a Kill-A-Watt to measure, for example, how much electricity your refrigerator or microwave uses, well, don't do it because those appliances may draw more than 1250 watts and overheat the wire, possibly causing a fire.



What is needed for use with the Kill-A-Watt is an extension cord that is rated for 15 amps or more. That will allow safe transmission of the electricity over the extension cord without overloading it.

I purchased a "Kill-A-Watt EZ" and use this 3' extension cable in conjunction with that. For background, the Kill a Watt EZ measures power consumption of anything plugged into it and displays watts consumed and if you enter your local utility's cost per Kw it will tell you what it costs to operate on a per day, per month, per year basis. The only issue is that you plug it into the wall and then the electricity consuming device into it, after, you have to get down on your hands and knees to view the reading. Kind of a pain to do. In using the unit with the CTG 3' Outlet Saver Power Cord I find it much easier to use.



What can you say about a 3' extension cord...It's a well constructed cord for the money and does the job intended.

I purchased a half-dozen of these to enable me to insert wide plugs and wall-warts into closely-spaced power strip outlets. Manufacturers often space outlets very close together in order to save money. These extension cords allow you to utilize all the outlets on a power strip.



Despite being very inexpensive, they are made very well.

These items do the job, I think, however, that one of them I installed from the wall to the Monster line conditioner and splitter should have been the same guage as the wire which comes out of it, but for that I would have had to buy a longer extension cord of heavier guage, defeating the purpose.

The only thing notable about this cord is that the black color is quite uniform; the writing on the cord is colored white but it is barely noticeable. That makes the color fairly neutral, which is good if you don't want it to stand out amongst other things.

Simple but quite useful product.



I have a UPS and a few powerstrips in the house. They are great by providing more outlets. But with all the power adapters that runs most of the gadgets today, even one of those power adapters can cover 2 to 3 outlets which defeats the purpose of having a powerstrip. The liberator solves that problem.



Also, some power adapters can be huge and heavy that its weight alone tends to loosen it from the wall, the liberator serves as a little extension to prevent it from loosening up. Loose connections are dangerous, it can produce sparks that not only can ruin your equipments but can even starts a fire. Countertop receptacles can also be problematic where they are awkwardly situated sideways.

I have about 20 of these in my home, all of them serving to connect AC outlets to a variety of chargers, power supplies, and so on. They are really handy and allow you to get those large power supplies (like for printers/scanners) off to the side, and out of the way from your power strips/surge protectors. This frees up more outlets on your power strip for other cords. I used one on my patio---the short (1 foot) extension cord allowed me connect a heavy timer and fasten it to the wall, away from the AC outlet.



A ham radio operator told me once that if you place all those heavy power supplies (that are off to the side of the power strip) on an old aluminum cookie sheet--- e.g., about 9x12", it will act as a "heat sink," thereby dissipating the heat. This is especially wise when those bulky adapters/power supplies are on CARPET---they DO get pretty warm. In theory, they should last longer---heat is an electrical device's worst enemy. So maybe that tip will come in handy for you. As always, be sure to observe common-sense safety rules when using anything electrical like these short extension cords. - Cables - Extension'
