User Michael Asked:

I'm trying to power a belkin tunecast 2 fm transmtter. The input hole is very small which adapter do i need? Thanks in advance for your help.

Our Technician Answers:

Most power supplies that are 12V come in one of two types of connectors. The vast majority of 12V power supplies between 1A and 5A (Amps) use the standard 5.5mm x 2.5mm connector. This covers over 95% of all power supplies... There is a small minority that use a 5.5m x 2.1mm tip.. These are usually in the 1A to 2A range... Please note that in many of the 2.1mm connector units, the 2.5 mm connector will still work as they are so close in size.

User Karen Ingish Asked:

I have a Christmas snowman (about 4 feet high) with a power adapator that fell and cracked and I need to replace. It's an AC Adaptor Plug in Class 2 Transformer Model AD-1202000AU Input: 120VAC 60 Hz 200mA Output 12 VAC 2000mA P/N GJE-AC57-124 It also notes Listed 8G10 (could be a 9G10) E200322 The plug in is two little fllatish and one roundish. (?) It's definitely not a barrel plug in. It runs the power for a light for fiber optics in this decoration. Do you have anything like this? I've looked all over. Thanks.

High K*** All te power supplies we carry have either a standard 5.5mm x 2.5mm DC connector, or a 5.5mm x 2.1mm Dc connector. For any non standard, you would need to cut off the tip that comes with it, and splice on a different one using electrical tape.. it is quick and easy...

User Daniel Brightman Asked:

Do you have any power supplies with a different connector than the 5.5mm one in your listings?? My mini router uses 12v power adapter a slightly smaller barrel connector.

Our Technician Answers:

Hi Dan. Yes, almost all our power supplies are available with a smaller plug. We list the 5.5mm x 2.5mm one on most pages because it is the most common, and covers 95% of all devices. We can however, if you request it, send any of the units with a smaller 5.5mm x 2.1mm blug. The 2.1mm represents the inner barrel diameter, and should work with some smaller devices. If you are unsure, I would recommend ordering the standard one however because it does cover almost all unit, and even devices that need a 2.1mm plug will actually usually function with slightly bigger 2.5mm one. Also, for larger orders, we can custom make any connector size.. This is possible for orders of 100 units or more, and will have a 10 day lead time. I hope this answered your questions.

Understanding Amperage, and Selecting a Power Supply.

This article addresses a commonly asked question, what does amperage mean, and how do I select the correct amperage power supply for my device.

Power Supply News

Amperage is an accurate measure of the amount of current passing any point in an electrical system (wire), at any given moment. If voltage can be considered the size of the the electrical flow, the Amperage is the speed of the flow; how many electrons pass a certain point in the wire per given number of seconds. When choosing the Amperage of a 12 volt power supply, it is important to realize that the Amp rating of the power supply represents the highest (maximum) load that it can handle. This means that a 12 Volt power supply rated at 5 Amps, can handle any load up to 5A, or 5000 mA. It would be safe to use that device for any smaller device or load, such as a 1A router, or 2A DC motor. It is not recommended to put a higher load on a power adapter than it is maximum rating. This will shorten the life of the unit, lead to quick failure, and possibly be a hazard. In order to find the maximum wattage of a power supply, you multiply the volts by the amps. For example, a 12 Volt 5 Amp power supply would be 12 x 5 which is equal to 60 watts. This means that the power supply can handle any 12V device, rated up to 60 Watts.
