User Liz Asked:

I bought 2 Christmas reindeer from a store the maker was Holiday Decorations. What I didn't realize was they were missing the adapters that actually plugs into the outlet. All they have is a round plug with only 2 connectors. 1 is flat like a regular plug that goes in a wall and one is round. It looks like this plug screws onto an adapter that will receive the flat and round plug. I have a picture I can send to you if you have a place I could upload it to.

User robbie Asked:

I have a 32" fiber optic snowman. What i do not have is half of his power cable.UL adapter input 120V 60HZ Output 12V 900mA. . The half that I need goes into the wall. Can You Guys Help ?

Our Technician Answers:

Hi Robbie... Finding a power supply to power your fibre optic christmas tree is easy. The first number you mentioned "120V 60HZ" is just the AC current as it comes out of you wall socket. You don;t have to worry about it. THe second numbers "12V 900mA" is the actual output of the power supply that you should be concerned about. 12V is 12 Volt, which is what most if our power adapters are. The measure 900mA is the amperage. To convert mA to A, all you have to do is divide by 1000. So 900 divided by 1000 gives you .9A. When dealing with Amperage for power supplies, you always round up to the nearest whole number. So you will use a 1A power supply. Here is a link to a power supply that will work for you,

User Eric Daub Asked:

I have a fiber optic Christmas Tree and the AC adaptor broke. Input: 120V-60Hz Output: 12V-Max 36VA. Do you have one that I can buy to replace it? Eric Daub

Our Technician Answers:

Hi Eric. Yes, we do have a power supply for your fiber optic christmas tree. The tree is a is very simple, and all you have to match is the voltage and the amperage. Since we know that the voltage is 12V, that is clear. We don;t know the required amperage, but we do know that is use 36 VA. Since 10 VA is equal to 1 A, you will simply divide by 10. So the power supply you need is 12V 3.6A Power Supply. In order words, you need a 12V Power Supply that can handle up to 3.6A of Load. In this case, you will round up to the nearest whole number, so you will use the Power Supply that can handle a load of UP TO 4A. So you will be using a 12 Volt 4 Amp Power Supply. Here is a link to the unit:

User Patricia Klein Asked:

I have a fiber optic Santa, 4' high, and I no longer have the adapter that goes to it. On the bottom it says "use only a 12v/25mv adapter" it also says no more than 20 watts. Can you help me determine which adapter I need? thanks. I'd love to get it "yesterday". thank you.

Our Technician Answers:

Hi.. In order to find out the size of power supply you need, you will use a very simple calculation. You already know that the voltage is 12V. You also know the wattage as 20 Watts... To find the Amp size of the unit, you will just divide the wattage by the amperage. so 20W / 12V equals 1.66 Amps... Amperage represents the maximum power usage your device needs so you need a power supply that can provide the same or greater amount of power. In this case, you would round 1.66A up to the nearest whole number, which is 2A... You can also use a bigger one if you wish, as the power supply will only give whatever amp load the device you are running needs.. Here is a link to the power supply you need. It is a 12 Volt 2 Amp Power supply:

User Jen Brothers Asked:

Hi.. I hope you can answer my question. I have a small hand router I use for carving in wood. It says it needs a DC power supply, and it is 60 Watts... I bought a 5A power supply, but it seems like it only works for a second, then the motor stops... What is wrong?? I tested the Power SUpply with something else, and it works..

Our Technician Answers:

Hi Jen, Thanks got your question. I know the problem. A DC motor has some special considerations when selecting a power supply. Your motor probably has a continuous use of 5A of 60 Watts, but that is only part of the picture. There is something else called peak power, which is the startup power necessary to get the motor running. The peak power is a lot more than the continuous use. When you press the button, for the motor to overcome resistance, and start turning, it usually pulls about 50% more power.. so for a 5A motor, up to 8A.. This happens for a second, then once it is spinning, it drops to continuous use power level. What is happening in your case is that the power supply has a shut-off circuit that protects the power supply... Once your load passes 5A, the power supply just shuts off... In order to fix this issue, you need a power supply that is larger than the peak power of your motor.. So if you are using a 60W motor at 12 Volts, you should order the 12V 8A, or even 10A power supply... Good Luck!
