User Greg Asked:

Are both of the outputs 12V/5A DC on the Waterproof 12v power supply? Can you attached them together in parallel for 10a? Thanks Greg

Our Technician Answers:

Hi Greg.. The 12V 5A Waterproof power supply only has one single output. The other 2 screw connectors are for the AC input. 5 Amps is the total maximum output of the power supply. In order to get 10 Amps of power, you would need to use two of these units wired in parallel.. but in that situation, it would make more sense just to get a 12V 10A Power supply... Thank you. Let me know if you have any other questions.

User Robert Britto Asked:

I have a Westinghouse tv model #EUM24F1G1 with a broken switching apapter the adapter is a 12 volt 3 amp adapter will one of your adapters work on our tv. Thanks Bob

Our Technician Answers:

Hi Roberto. Although I can't answer questions about specific models, I can let you know about the specifications in General. These power supplies are very standard, and all 12V DC 3A power supplies are actually the same. THe only difference is not in the electrical current, but in the quality of the power supply... and the connector used. 12V 3A power supplies will usually have a single barrel type 5.5mm x 2.5mm dc connector. If you look at the old power supply, or the the place on the TV where you plug the power supply in, and you see a simple round connector about 5.5 mm in diameter, then it is a standard conenctor, and this power supply will work. The other decision is whether to get the UL listed one, or the standard one. The UL listed power supply is higher quality, and should work longer.... although it is a little more expensive. For home use, the cheaper standard power supply will probably do the job just fine. The only difference is that the UL listed one has a 2 year warranty and the standard has 1 year.

Our Technician Answers:

Hi Michael. The power supply you are looking for, the 12V DC 2A Power Adapter is a standard unit that is available on the main page of the site. It come with the standard DC connector which 5.5mm x 2.5mm. This matches your specs exactly. It comes in two version, the standard unit which is great for normal household application, and the UL listed unit which is a little more heavy duty, and is great for more sensitive equipment such as lab or medical devices, high end audio or video gear, or any situation where failure is not an option.

Power Supply News and Information

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.
