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

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. Here is a link to both of these power supplies: Standard 12V 3A Power Supply: http://12vadapters.com/adapter/power-supply/12v/3-amp-3a.html UL Listed 12V 3A Power Supply: http://12vadapters.com/adapter/power-supply/12v/3-amp-ul-listed-12-volt-3a.html

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.

User Richard Asked:

Hi I want to use your 12V 10A power supply to power a car radio I have in my garage. Is this supply designed to be plugged into a 110V wall receptacle 100 percent of the time, even when the radio is turned off and drawing no power? Also what is the power supply current draw when it is plugged in but not supplying any power? Thanks Richard

Our Technician Answers:

Hi.. The 12V 10A Power Supply is Ideal for powering a car radio at home. Please make sure that the total watt usage of the car stereo is not more than 120W, which is the maximum load possible for this power supply. If the radio is turned off the power usage is almost zero. The power supply only turns on when there is a load on it... So you don't have to worry about the power supply passively using power.

Why Order Your Power Supply from an American Company

This article discusses the benefits of ordering a 12V Power Supply Adapters you need from a company based here in the USA, versus importing direct from China.

Power Supply News


As a USA based manufacturer, wholesaler, distributor, or retailer, you are faced with some tough challenges and choices daily. Importing power supplies to power your products does not need to be one of them. While it is true that at first glance, buying a 12V power supply a little cheaper straight from China looked at closely, the deal may not be so good. Here is why. First of all, shipping from china is slow and unreliable, not to mention expensive. While many factories promise great price, and initially low shipping cost, it has been my experience that as soon as they have the business, they will start pumping the shipping cost higher and higher, even if they charge the same for the unit itself. The second problem with buying straight from overseas is the failure rate. It has been our experience that manufacturers will cut corners and cost as much as possible. If you do not know the factory, and have a long term relationship with them, they will use the cheapest possible material, lowest gauge wiring, thinnest plastics. This translates into an extremely high and rising failure rate. If you buy your power supply here in the US, if it fails, you can return it. Buying from china, you are out of luck as return shipping is super expensive. Once you figure in the cost of replacing failures, including buying and shipping them, the cost is no longer so low. Finally, it has been our experience is UL listing. If you need to have a UL listed power supply, both for the certification of your product, as well as for safety and quality, it has come to our attention that a vast portion of listing on Chinese wholesaler sites are issuing fake UL listing stamps. This means that the power supplies are of inferior quality, have a higher failure rate, as they do not comply with UL minimum quality standards. Worse yet, they are often stopped, seized by customs on entry, leaving you with the disposal fee, and possibly a fine. We have seen this over and over again. So, to sum it up, because of cost of shipping, importing, quality control, high failure rate, and fake UL listings, it seems like buying your 12v Power Supplies from a US based company, shipping from within the US, offers you the best protection, best lead times, and in the end, the best price.
