R-Tech12v Power Adapter, 1A Power Supply, AC 100-240V to DC 12V 1A, UL-Listed, Power Cord with 5.5x2.1mm Tips for LED Strip Light, CCTV Camera, Router, DVR, NVR and etc

I have some light stips that took some time to put up. well, 3 of 10 of them went out because the power supply failed. I cracked open the power suppy using a vice, mostly because it was cool to do that, but also to see what was inside that failed, shure enough black blown components. Ok, so after that useless sentence, what can I say about this product? I spliced in my wires from the old powersupply and the lights lit right up. The powersupplies seam robust enought and i have 2 left over now. Bonus.NOTE: When you buy this product you need to make sure of the following. 1. The voltage must be the same, too low and you are not going to have enough power and your powered device may not work properly. To high voltage and you are going to greatly shorten the life or your device. 2. Amps of the old powers supply must be the same or it can be a lower number than this one. If the old power supply has a higher amperage this will cause the device to be power starved and it will soon overheat this new powersupply. Lastly, watch the polarity. The polarity of the AC adapter’s connector must match that of the power input or charging port on the device. There are two types of connector polarities: center positive and center negative. If your old one is center positive and this one is center negative, that may damage the powered device. You could cut the wire and flip them but I would research that.Out!

Always searching for the best deals for the money, not cheap deals, best deals. Was having some wi-fi camera problems and after troubleshooting the problem I found that it just needed a new adaptor cord. So. like always I bought more than I need just in case my other cameras end up with the same problem. I purchased the 5 pack for OOSSXX wi-fi cameras and these met the specs and work with no problems. the cord length is 5 ft (60 inches). These are worth it to me most definitely.

Needed two, but the price was good, so I got spares. Voltage is correct. So they work.

This five-pack of 1 Amp adapters seems to be a good buy, and their "90-degree" design allows them to be plugged side-by-side into duplex wall outlets or normally-spaced outlet strips. When I "bench tested" the five units on 110V AC input, I found that their no-load outputs were between 11.98 and 12.00 Vdc (they are rated for 12Vdc @ 1 Amp output); I have load devices that are 400mA (0.4 Amp) each. The output voltages of the adapters dropped to 11.92-11.94 Vdc with one load device (0.4 Amp) connected, and to 11.85-11.88 Vdc with two load devices (0.8 Amp) connected. I did not try the adapters with 220V AC input (they are rated for 100-240V AC input) because I will be using them only on 110V AC. I did not detect any problems during this brief testing.The downside (for me) is that their "90-degree" layout with fairly long length actually prevents them from fitting in the recessed outlets that I needed them for (which can accommodate only one conventionally-oriented adapter). This is a "non-standard" application, so it is not a deficiency of the adapter, but just an unfortunate artifact of the special design that allows them to work better in NORMAL applications.My average (three-star) rating comes only because my inability to use these adapters prevents me from making any assessment of their long-term behaviors, including their "life expectancy".UPDATE / UPGRADE (4/15/16): After having several of these units in actual use (in "standard" AC receptacles) with cameras or IR illuminators for a couple of months, all seem to be working well - and have survived fairly cold (near 0F) temperatures in unheated buildings. They are being used with loads that draw various currents, and I have even used some of the units with loads which draw the full rated 1 Amp, or slightly more, all without any ill effects. (In fact, the only "problem" that I've found is that one set of five units all had some unknown tacky liquid on the housings - not sure what that stuff was, nor why it was there). Because of the satisfactory performance so far, I've raised my rating to four-star. If they continue to work well over long-term, they may warrant a full five-star rating.

works good

Using to power security cameras. Works just as good as the OEM adapters I was using for much less. Do recommend.

Works perfect for my project and even replaces a few I lost.

Perfect for most of my gear!!I was tired of losing my synth adaptors at gigs and now have a studio set and a gig set with backups.:)

SI, son buenos de muy buena calidad.
