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

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.

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!

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.

These 9vdc 1 amp adapters [i have 8] are used for guitar pedals I have over the yeas purchase many other brands only to have them fail in a year or two These have not failed in my experience no doubt due the superior regulation design from other sellers these provide very consistent power regulation, very sturdy construction thick plastic housings with a good quality cable and output connetor highly recommend

worked for the lamp we had !

This power supply doesn't output it's rated amperage. Measured with a load at 1.8amp max with LEDs and a meter. Also it sparks to the receptacle which is likely not safe.

Works great just like the original one.

I used the product to replace my faulty HDTV8 TV box power supply cord and transformer 120/240 VAC to 5VDC- 2A.

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

It works but not a great quality

Works with my Ring 2 stays charged all the time

L'adaptateur n'as duré que 2 mois. Maintenant, quand je mesure juste l'adaptateur sans "load", il donnes toujours 5 volts, mais il cesse de fonctionner des que j'y branche de quoi dessus. -EDIT - Apres publication de mon review, ALITOVE m'ont contacter pour offrir une prise de remplacement. Le nouvel adaptateur fonctionne corectement, et ils ont livres rapidement. On va espere que ceui-ci dure plus longtemps, sinon je mettrai un status ici.

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