ALITOVE 5V 10A Power Supply Adapter AC/DC Converter 100-240V AC to DC 5 Volt 50W 10Amp 9A 8A 7A 2A Transformer with 5.5x2.5mm Plug for WS2812B WS2813 WS2811 W2813 SK6812 LED Strip Pixel String Light

Nice and well functioning power supply. Used it for an Arduino based display board.

Good product

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.

WARNING: Check the output voltage before connecting anything to this power supply. I purchased this as a 5V supply for addressable LEDs and measured approximately 5.5V at the output. That may not sound like much, but for many 5V devices, LEDs, and microcontrollers, 5.5V is the absolute maximum rated voltage. A product advertised as a 5V power supply should not arrive adjusted to the very edge of the specification. Had I connected this directly to my project without checking it with a multimeter, I would have been unknowingly running my hardware at the maximum allowable voltage from day one. Most hobbyists buying this product are unlikely to verify the output before use. This is not a minor issue. A power supply is the foundation of the entire project, and poor voltage calibration reflects poorly on quality control. If a manufacturer cannot ensure a 5V supply ships reasonably close to 5.0V, it raises questions about what other aspects of the product were not properly tested. I cannot recommend this product. There are too many reputable alternatives available to risk powering expensive electronics with a supply that arrives significantly out of adjustment. Buy something else and save yourself the headache.

The power supply delivers 5V but drops a bit on loading and doesn't regulate a fast varying load well. It should be OK for string lights, but I wanted it to power electronics.

This is a great power supply. I got it for an LED project and it is working fine. Provides enough power to power the LED display.

Value is absolute zero. I ordered 2 power supplies rated at 12vdc, 5amp. The 1st power supply put out less power than rated and wouldn't operate my device. 2nd supply didn't power up at all. What a waste of time and money. I hope Amazon will refund. I have an old 12v,4a supply that works infinitely better.

The power supply adapter provides a relatively clean signal, and gives plenty of current for driving WS2812B LEDs.

I used it on 8A device and it blowup from the side after 30 minutes of use only. Fortunately nothing caught fire. If you need it for high amps devices take at least double the required amps to be in safe side.

It has a grounding issue, it doesn’t have a stable current. Cannot use it for my LED lights. Bought 2 and both are faulty
