User Cindy Asked:

I need a power adapter for a brookstone digital picture frame, model AH 812-B requires a 12 V DC..any clue what I might use

Our Technician Answers:

Hi Cindy. We are unable to give you information about which power supply to use for a specific device, but it is easy do do this research on Google. All you have to do is find the Voltage of the power supply, which I assume will be 12 Volt. Then you should find how many watts your device uses, and divide by the voltage (12) to get the Amps. Now you just order a power supply that has the same, or HIGHER amp rating than your device. For example, if you TV is 12 Volt, and uses 60 Watts, you will divide 60 by 12, to get 5 Amps (5A). This means you can use a 5A, 6A, 7A, or any higher Amp rated power supply. Also, make sure that your TV uses the standard 5.5mm x 2.5mm DC connector, which is what all the units we have come with,

User bob secrest Asked:

i have a schwinn 230 recumbent fitness bike that needs an electrical power adaptor. do you have one to fit this bike? i think it takes an adapter #13006109. thanks

Our Technician Answers:

Hi Bob... In order to find the correct power supply for your bike, you will need to do some research. First you need to find the voltage of the original power supply. This voltage has to be exact. So if your bike uses a 12V Power supply, You will need to use another 12 Volt Power Supply. After that you will need to find out the size of the adapter it needs, measured in Amps. If your bike used a 4 Amp power supply for example, you will need a power supply that can handle a 4A load, OR MORE. So a 4A, 5A, 6A, etc. will work. Finally you will need to know the type of connector. This should be easy as most devices these days use a standard connector that is 5.5mm x 2.5mm barrel type, center positive. That is what all our power supplies have. So confirm that the bike uses that standard connector. You can look up a picture of the connector on google. That is all. If you match all these things.. It will work.

User john Towler Asked:

I am looking for a 17 v 400mA adapter. Can you supply this or one that will work to charge a power drill battery?

Our Technician Answers:

Hi J*** For charging your drill battery, you need a 17 Volt Power Supply that is cable of about .5 Amps. The only power supply that can do this in our stock is the 90 Watt Universal power supply. It will work perfectly for your Drill. Here is a link:

Power Supply News and Information

What Is a an AC/DC Power Supply, and What Does It Do?

This article tries to explain the function of an AC/DC power supply by showing the difference between AC and DC current, the two major forms of electrical power that exist today.

Power Supply News

All the 12V Power Supplies you see on, and most other websites serve one single function. They take AC Power (Usually 120V or 240V, or anywhere in between), and transform it to DC power, usually between 12V and 14v. In order to understand this concept, you have to understand the underlying difference between AC and DC electricity. AC and DC are the two existing forms of electricity. AC stands for Alternating Current, and DC stands for Direct Current. As the name implies, DC runs in a single direction and direct line from positive to negative poles. AC on the other hand alternates its motion in one direction, then in the other, usually on a cycle of 50HZ or 60Z. This means that it changes direction 50 or 60 times per minute. While the generator of a DC current has a fixed magnet, and fixed positive and negative poles, the generator of an AC current has a rotating magnet. The rotation of the magnet reverses the relative position of the negative and positive poles 50 or 60 times a second, thus alternating the flow of the electrons in the wire at that rate. Initially both of these systems were in competition for wide adoption. Thomas Edison was a big proponent of DC power, while Westinghouse was pushing the use of AC current. In the end, AC current won because it travels much better over long distances. While DC current can only travel about 1-2 KM over electrical wire until it starts losing voltage, AC current can travel hundreds of KMs at a time. Currently, all household current is AC, but most small devices run on DC, which is the more stable and non-oscillating of the two currents. So what an AC/DC power supply does is that it takes the AC current that travels well all the way to your house, and converts it to DC current, which most electronics and motors run on.
