ALITOVE 5V 3A 15W AC 100V~240V to DC Power Supply Adapter Converter 5.5X 2.5mm 5.5x2.1mm Plug for WS2812B WS2811 WS2801 SK6812 LED Pixel Strip Light CCTV Camera Security System

Worked Perfect! These were for a 3D printed project using y Creality K2 Plus.

My cob lights have been running for 4 years on and the USB plug toasted instead of a USB plug I cut it off and ditched the USB block for this permit replacement option

Giving this 4 starts due to the fact that while it works and delivers 5 volts, when I hooked it up to the 5V inputs on the vintage computer I needed it to power (Commodore 128), it caused a noise / interference pattern on the monitor display. Switching to another 5V adapter I happened to have laying around resolved the issue. So, if you need something for sensitive electronics, I would pick a different one.

Inicialmente había pedido 2, pero después pedí otros, son muy confiables, una cosa que me gustó el la fiabilidad en el voltaje, pues su variación es muy cuando se le aumenta la carga, es recomendable leer la reseña que hace el vendedor, también hay que respetar la carga aplicada, la cual es recomendable que esté sobre el 70% para evitar recalentamiento, lo recomiendo mucho para proyectos que no requieren demasiado amperaraje, y como dije en un principio, el voltaje es muy confiable

I teach digital electronics at a local school. I needed to order 8 power supplies for class. Which can be costly! And with the lead times to actually get...I was lucky to stumble across these! The fact that it can supply 5v @ 3A And that it has the nifty connector on the end, where i could attach solid 24 AWG wires to plug directly into my breadboards was ideal! These are small, available!, affordable and worked perfectly to power our digital circuits, with power to spare! Will be buying more of these as needed!

These are a fire hazard do not use them. The connectors are poorly made. I checked on the device that it was powering because it was acting strange and noticed that the included plug was literally melting. Good thing I checked it before it lit my house on fire. I verified that the device it was powering did not have a short or was improperly wired.

Did not Fit as described. I return with no problem.

I have some inexpensive battery powered under cabinet LED lights. They use 3 AAA cells, each, and work great. But, they were going through batteries so quickly that I rarely used them to avoid the expense of replacing the batteries. These power supplies produce about 5.1 volts of dc. That's about 1/2 volt more than the the combined voltage of the AAA cells but It seems to work without any problem. The power supplies come with an adapter that easily attaches to the wires I soldered to the battery clips in the light units.

Works with my Ring 2 stays charged all the time

I liked that this power chord works great but wished they made a longer chord. Nevertheless, im happy with it!

Would give 4.5 if possible...a 5 out of 5 if I knew they would last for years. Just do not know at this point. Reasonable price. Using these with JustAddPower HDMI transmitter and receivers as well one for my Display Port Hub which provides PC output to three screens.

Can't rate the quality as I can't use it. I can't find how to return the product.

it take charge and it get hot
