Kammoy 2PC Led Class 2 Power Supply US Plug Adapter Waterproof IP44 Low Voltage LED Driver Transformer Replacement Part for LED Light (12V9W) (Black)

I have an existing outdoor low voltage, white string of lights. The controller is labeled as an Intertek 501191. This controller no longer works. I tested the existing string with a different set's controller and the set works fine. So, I was confident a new controller would allow the string to work again. The string isn't terribly expenstive but we enjoy the variety of lighting effects it makes, so we wanted to keep it, if possible.I had trouble locating the same controller 5011191. I found the description for the device I'm writing about now and noted the specifications for its input and output were nearly a match, plus the description of effects this controller makes seemed consistent with the original.Upon arrival I noticed the two controllers are not quite the same size; the new one is a bit smaller. Uh oh, I thought, maybe this won't work. I attached the new controller to the lights, plugged in the controller to power and switched it on. Shazam! It works like a charm and has been problem-free for usual Christmas season nighttime use for around a week now. I'd say we are back in business and I'm quite pleased about that. Five stars.

This worked as expected for the most part. It was shipped in ridiculously quick ship time. Its sort of unfair of me to give it a 4 star instead of 5 but the reason for not all 5 stars is it did not fit for the inflatable blow up that I thought it would. the male receptacle on this was slightly larger than the one I was replacing. I wound up using it on a different one, and then played musical inflatables. 4 stars to give people pause to make sure that they measure the one they need first

I bought this as a replacement bc my dog chewed up the original power supply for a Christmas tree that gently twinkled when lit up. This power adapter caused the tree to flash very abruptly. The flashing was like a strobe light on my front porch and I thought if I invited family over, one or two of them might have an epileptic seizure. Although I wouldn’t mind it if a couple of my relatives did that, this power supply was not a good solution.

Just what we were looking for. Our power supply on our Christmas blow ups first stopped playing music, then stopped all together. This fixed it.

Did a lot of troubleshooting before we bought this. It is perfect! It now works again. I’m so relieved.

Bought to replace the one that dies on mine and this didn't work. But seller was amazing and quickly resolved the issue! Excellent seller.

This power supply replaced the one that broke on my inflatable Halloween decorations. Unfortunately the part that screws into the adapter was too small so I had to improvise and wrap electrical tape around it to keep moisture out.

I was replacing a broken one on an inflatable and got this same input and output as the existing. I plugged it in and it worked until it was turned off and it never came back on.

Funcionó perfectamente para un inflable chico (1.40m alto), solo ojo con la conexión que necesitas ya que existen varias para los inflables y con el voltaje que debe tener.

Peut-être un bon power supply mais ne fessait pas avec mon filage

Says it works on inflatables well not this one
