12V 2A Power Supply, AC 120V to DC12V 5.5x2.1mm Jack Converter, 12 Volt LED Driver 24W Adapter Transformer for Strip Lights, Surveillance Cameras, External HDD, Monitor, CCTV (Pack of 2)

Works great

Purchased these to replace the old power supply for my under cabinet lighting. These worked perfectly and are silent. My old power supply had an awful buzzing noise I delt with for years.

I have several decorative yard inflatables for Halloween and Christmas.Most of them use the Gemmy 12 volt AC Adapter.Those adapters are not sealed, the clam-shells are put together and tapes so they don't fall apart.They are in no way waterproof or even water resistant. (Strange for an outdoor product.)Well, we had a really bad wind and rain storm, and water penetrated two of them.One blew, and one I was able to fix.Replacement Gemmy 1 amp adapters are 11-15 a piece.I picked up a 2 pack of 12 volt 2 amp adapters for 13 that come with the barrel to terminal adapter.I took a part the Gemmy adapter and de-soldered the DC connector and screwed it into the terminals of the SANSUN adapter.I then taped it all up and plugged into the barrel connector. I then taped, or shrink tube around that to seal it up.Works like a champMy original Gemmy adapter was only 1 amp, but I got these two amp ones so I can drive two inflatables, so I can cut the cost even more. Also, it gives it a little overhead as the Gemmy adapters get quite warm.I am docking it one star, because the barrel connector of the SANSUN AC adapter has a very sloppy and loose fit to the barrel to terminal adapter it came with. It comes off too easy!!!Not the end of the world for me, because I was taping and sealing it closed to weatherproof it.Latest Update: 2019-11-5I have never experienced a company try so hard to make things right. (Anker comes to mind as well.)When I had an issue, they reached out to me to make things right.This is very rare today.I am grateful they have reached out to me to replace them.Update 1:1 of the adapters failed after 2 weeks.I have contacted the company, let's see if they do something about it.Since I already threw away one of the boxes of the 2-pack, not sure if I can return to Amazon.Update 2:Seller was quick to respond and is sending a replacement!Update 3:The replacements 2A are dead too now.Some with very minimal use.The 5 AMP model died after a week, with only a 1-2 amp load.

I was able to adapt it to my outdoors landscape lights.

LED lights were needed for a remote water and gas utility reading solutions via WiFi/Internet control I was cobbling together. I am using a WiFi managed power outlet for the WebCam and LED light power supply units. When I want to read the meters I remotely turn on the WiFi power units, which turns on the WebCam and LED strip power supplies. Within 30 seconds I am able to take pictures with the WebCams of the meter readings. Once done I turn the WiFi power units off until the next time I want to see the meter readings. I ended up using 6 to 9 LEDs per strip I cut from the reel of the master LED strip. I used the LED strip self-adhesive backing to attach the LEDs to the base of the WebCam units. The illumination turned out to be excellent. I did not need to dim the LEDs, but was ready and able to do so if needed.

Used for LED aquarium lighting, works well.

For my aquaculture I needed to purchase food grade centrifugal pumps, but most were far outside my price range, aside from small units that lacked their own power supply, of which we went with this:TopsFloTLB0810LFor that, I purchased a pair of these.In our setup, we have to use an outside space and while we take every effort to protect the wiring, eventually water damage occurs, and this product is no different. Thankfully, when water does damage these, it doesn't result in a short to the pump motors (which is off the market now and therefore irreplaceable) so we have purchased this product multiple times and keep extras on standby. I cannot fault this product for what happens when exposed to water, but I can credit this product for not letting it damage the attached device.
