User Brenda Woodall Asked:

I need an AC-AC Adaptor for a inflatable outdoor decoration the model number Is JXA-12V1700-IP44. Where can I find one and how much do they cost.

Our Technician Answers:

Hi Brenda. All the power supplies we sell are AC to DC. This means that the input is normal 120 Volt or 240 Volt household current, and the output is DC (Direct Current), usually 12 Volt, similar to what you have in your car. For an AC-AC power supply I would suggest your local electronics store...

User Mike Asked:

I need an ac adapter for a Uniden BCT8. The specs are 12V DC 500mA. Should I just order the 12V 1A? Thanks for your help.

Our Technician Answers:

Hi Mike. Yes, that is exactly correct. You will round up to nearest whole amperage, so the 500 mA, which is the same as .5 Amp, will round up to 1 Amp. The 12 Volt 1 Amp power supply will work for you.

User Kit Autry Asked:

Had a fire 3 yrs ago and just retained a couple of 500 GB External hard drives but, no AC adapters. The first one is, a SeaGate DeskTop 12V output, 2AMP 3.0 USB. P/N 9ZH9P77-RAA. With an, SS computer plug on it The second one is a Western Digital, MDL: WD5000D032-000. I know that it is 12V But not sure if it is a 2 AMP or a 3 AMP. it has, what appears to be, 3 plugs. One computer and , 2 fire wire. The DC plugs are differant size per each model or P/N. If you could help me figure this out? it would greatly appreciated and, I could retain some of the files that were thought to be lost in the fire. Thank you for your time. KA

Our Technician Answers:

Hi Kit. As far as the Amperage and Voltage of power supply, it is simple. They are both 12 Volt, so you can use the same adapter for both. In this case, since one is 2 Amp, and the other 3 Amp, you will use the higher rated one. The 3 Amp, which is the maximum load you can put on the power supply, will work for both. As far as the connector, all our power supplies come with a standard 5.5mm x 2.5mm DC connector. You will see if this matches your device.

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.
