User Bryan Asked:

I have an indoor camera with a 8ft cord. When I replaced the cord with a longer one 15ft and the night vision IR's come on the camera cuts out. What power supply can I use or am I not going to be able to use the longer one. The current supply is 5V 2.0 A I don't want to burn up the camera with the wrong one. Any help would be helpful. Thanks Bryan

Our Technician Answers:

Hi Bryan. With DC loads, there is a loss of voltage that increases the longer the cord is. The solution for this is either to use a thicker (higher gauge wire), or to use a higher amperage power supply. Or to place the power supply closer to the camera, so you can have a shorter DC cord, and a longer AC cord as AC power carries better over longer distances.

User Robert Praski Asked:

I need repleacement power adaptor for Seagate external drive 4T. the specs on burned old one are: AC input 100-240V > 50-60Hz; 0,65A Max; 51-80VA; DC output 12v - 2A; plug external "-" internal"+" Old Manufactured by Asian Power devices Inc.Model #WA-24E12 S/N 849284088. I need something compatable to that - don't want repleacement. European power connector. Thanks ROB

Our Technician Answers:

Hi Rob. Looking at the specs you sent, it is really easy to fine the correct power supply. The input you don't have to worry about because it is standard in all of USA. The DC output is the important part. In this case I see you need a 12 Volt and 2 Amp DC Power Supply, and that the connector has to be center negative. Here is a link to the unit that you need: http://12vadapters.com/adapter/power-supply/12v/2-amp-2a.html

Power Supply News and Information

Not ALL Power Supplies are Created Equal.

This article discusses the quality differences between different types of 12 Volt Power Supply Adapters, and how to choose the best one for your application.

Power Supply News


These days, the choice in Power Supply providers is huge. You can order from a supplier within the US, or from one across the planet. You can find power supplies on major chain store web sites and little specialty suppliers. They range in price from as little a few dollars, to fifty or more dollars, but what is the difference between a cheap power supply, and a really expensive one. If you can get a 12 Volt 5 Amp Power Supply for as little as $10, and as much as $70, what is the real difference, and how do you choose. To begin with, it is important to know that not all power supplies are created equal. Real quality differences do exist. The cheapest power supplies on the market can be made with subpar components. They might have low gauge wire that can barely hold the necessary current. They can have resistors and components that can fail within a few hours of use. Even when they don’t fail, some of the cheapest power supplies can put out unsteady levels of energy. Voltage might vary by as much a plus or minus 15%. This will inevitably damage your electronics. The question is this, what is the cost of the power supply failing? Is it worth risking a $1000 screen, or all the data on your hard drive to save $5 on a power supply? And if the power supply fails, what is the replacement cost, what is the down time waiting for replacement of the defective adapter? It is often worth it to spend a little more on a quality component, then risk the damage and replacement cost of a substandard one. Does this mean that a more expensive power supply is necessarily better? Not by all means. Sometime the same power supply is sold for $10 by one supplier and $50 by another. So how do you choose? One thing you can look at is UL listing. If the power supply is UL (or CE) listed, you can be sure that all its components meet a minimum standard of quality. It also means that it receives a higher level of testing. UL listed power supplies are almost always better. Another way you can tell if a power supply is a high quality one is the warranty. Does the supplier offer no warranty, or a short 90 day warranty? That means the supplier does not stand by their product, and has no confidence in it. If on the other hand the supplier offers a one year long or more warranty, it means they are confident enough to assume the cost of unit failure. It is not a total guaranty, but it is a good sign.
