ALITOVE 5V 10A Power Supply Adapter AC/DC Converter 100-240V AC to DC 5 Volt 50W 10Amp 9A 8A 7A 2A Transformer with 5.5×2.5mm Plug for WS2812B WS2813 WS2811 W2813 SK6812 LED Strip Pixel String Light

NIce power supply – exactly as described.
Great little power supply for my lighting project./ Works exactly as described. It is silent, and compatible with the lights I needed it for. The price seems right on point with other similar products.

Not enough power/unstable for WS2812B
Update 10-8-18: Customer service is working with me to resolve and diagnose the issues. Attaching the power to both ends appears to be solving the issue even without a capacitor as I had to use previously to get it partially functional. They have additionally sent me a working replacement of the two I purchased that have had no issues and did not require the power to be attached to both ends.I purchased two sets of these, returned the first one assuming I was just unlucky. The second set was not much better. Using an Arduino and WS2812B LED strips from same seller and I could get at most 1 change in color before they locked up, I assumed software or some other issue, but I had purchased a PS from them a couple of years ago and it worked fine, no problem even when voltage dropped near the end I could rapidly change the colors/brightness.I was able to get around the issue with the use of a capacitor on the newer ones, but I still could not go past about ~120 brightness depending on saturation before it would lock up while the older one (again same model) would do just fine at bright white, nothing else needed.Not sure if I’ll settle or return and try a different brand, but after 4 and none working out of the box I would not recommend.

Danger! Failure at 80% load!
Short review: This power supply is dangerous! Not only did it fail to deliver 80% load in optimal conditions, it also got stuck in an overheating fail state for at least an hour! The only good thing I can say is no fires or melting occurred.Long review: I purchased a 5V 10A version to replace a lab power supply for an 8 x 18650 battery tester. The peak current draw of this end device is 8.2 amps, verified on the lab power supply. I set the new power supply on the cold concrete thin side down and started all 8 channels, waiting 10 minutes to make sure nothing heated up excessively. I came back a couple hours later, the tester was cold and powered off and the power supply was painfully hot. Thankfully the batteries and tester were fine, based on the graph data the power supply failed shortly after I left and remained in that fail state for a long time. I’m glad my test setup was in the garage on a cold concrete slab, things could have played out differently if I tried this on carpet.

Poor voltage regulation
Mine puts out 5.56 Vdc at light loads, which is pretty poor regulation. My WS2812B LED strip calls for 5.3 V absolute maximum, so I’m afraid I might damage my LEDs.

I have this power supply connected to an ESP-32 running WLED and an addressible RGB Strip (5 meter, 60 led/m, 300 led total, maximum possible draw of 18 amp, limited to 12 in software for the longevity of the power supply & strip.)Initially, the power supply worked with 0 issues with the positive and negative wires connected to the included DC Jack/Terminal. Unfortunately, after about a week of usage my lights suddenly stopped working and isolated the issue to be related to this power supply.The reason this product still has a 5 star review from me is the amazing customer support, I contacted them and within afew days of my original unit breaking I received a new one in the mail, but the story doesn’t end there.While I was waiting for my replacement I discussed my issue with some others and read more reviews of this product, which had complained about the DC Jack, so when my new unit arrived I decided to investigate. And the other reviews were right, when I swapped out the Screw Terminal for the one in my replacement, the lights worked again, the actual power supply had never died, just the adapter.Unfortunately, after only afew hours of usage with the new adapter, I lost power ONCE AGAIN! I decided it’s probably in my best interest to skip the adapter and to simply strip the wires on the power supply (if you think about it, it goes from wires, to male DC, to female DC, to a spot to plug in wires, to wires, it’s simply one more point of failure.)Since I stripped the wires and connected it completely I have experienced 0 issues with the power supply, and would recommend it to someone else trying to make a diy argb lighting solution, but I would recommend them to strip the wires from the start rather than using the Terminal (and I belive I would recommend this regardless of the power supply used since I have gained knolege from this experience)Photo 1: Afformentioned Screw TerminalPhoto 2: Lighting power solution after wired have been stripped

Thanks, exactly what I needed. Good price and quick delivery.

Used this to power some smart-RGB lights. Works great.
