User JC Cole Asked:

I have a surveillance System that I would like to use for a rear view camera on some equipment. Can I use an adapter and plug into the 12 V cigarette lighter/s? The stated power supply info is: input voltage 100-240 V AC @ 60 or 50 HZ and operating voltage is stated at 5V DC @ 1 amp and power consumption 650 mA max. Haven't a clue what that means, I just want to use it in the truck/trailer. Thanks!

Our Technician Answers:

The power supplies we sell as AC to DC converters, THe power in a car is already DC, so you cannot use our power supply in a car. What ours do is they take the power from the house outlet (AC) and make into into the power you use in your car (DC).. It is for use at home.

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.

I have a POSBANK Anyshop D510 POS system. Needs a new power adapter. It is a 4pin 12v 5a adapter. The unit linked here,, looks like the correct adapter. Do you happen to know if this is used as a POS power adapter?

Our Technician Answers:

Hi A. THe power supply you provided a link for is a standard 5A unit, with a 4 Pin connector. If you look at the picture, you will see the square 4 pin tip. There is only one connector that looks like that. So if the connector in the picture on the website looks the same, then it will work for sure. Thank you for you question.

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. Here is a link to both of these power supplies: Standard 12V 3A Power Supply: UL Listed 12V 3A Power Supply:

User Michael Abildtrup Asked:

I need: Power Supply: 12-Volt. 2-Amp Output; Power Supply Barrel: Outside 5.5 mm, Inside 2.5mm (Positive Center) Which one do I order?

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.
