User Johan Smelte Asked:

Can I use the standard 12v power supply in an outdoor environment such as pool side?

Our Technician Answers:

Hi John. The standard power supply comes with a sealed case, so a little splash will most likely not hurt it... but if it going to be in the rain all the time, and in an area of high humidity, I would recommend using the waterproof power supply available on out site. It can be in direct rain without an issue, and is also better for use in high humidity areas because it will not corrode... Let me know if you have any other questions.

User Jerry Gardner Asked:

I am trying to find a replacement AC adapter. It says LITEON Motorola part no.524475-25 Model PB-1320-01C-ROHS ReV01 Do you supply this? or an exact equivalent?

Our Technician Answers:

Hi Jerry. I am not allowed to answer a question about a specific brand (accept for companies such as Seagate that refers clients to us). In order to find the correct power supply, I recommend that you research the model number in google, and find the voltage and the amperage which you can match on our website. You can also check for this information on the old power supply if you still have it and it is broken, or on the back of the device that you are trying to power. As long as you match the Volts and Amps, you should habe no problem finding the correct power supply.

User SAMANTHA Asked:

i have a zoombox projector i need a 12.0 v dc power cord to run it. where can i find one? what amperage would i need?

Our Technician Answers:

Hi Samantha, You need to find out the voltage and the amp rating of your projector.. Looks like the voltage is known at 12 Volts, so you need to know the watts, or the Amp.. If all you find is the Watts, divide by 12, being the voltage, to find the Amp rating of the power supply you need... Also make sure that your device uses the standard connector, which is a barrel connector with a whole in the middle.. It should be about .5 CM wide.

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 12vAdapters.com, 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.
