Universal 24W AC Adapter Kit, DC 3V 4.5V 5V 6V 7.5V 9V 12V 2A 2000mA 1A Power Supply for LED Strip Light CCTV Camera Speaker Router, DC Round Adapter 5.5mm2.1mm

Seems to be a good quality product. Output at 6 volts, with no load, measures about 6.2 volts, which is fine. Under load that probably drops right to 6. I'm using one to power two 6 volt hobby motors, and the 2 amps at 6 volts is more than enough capacity to power both with no slow down. I'm using the other to power 3 3 volt devices. At 3 volts it supplies 4 amps, which is more than enough. Easy to adjust the output voltage with just a regular screwdriver. They work great for my needs and the price is right.

I do a lot of testing and dealing with used displays and modules. I have power supplies everywhere and this helped keep the pile clean. I eliminated 6 different supplies by having the adapters and voltage selection for common Esp32 and RasPi project parts. This helps to keep the clutter down and works for low power items very well.

Pretty awesome kit! Had trouble finding the adapter I needed but this had it, and works perfect. 👍

So far a great little charger. All the different adapters are definitely handy. My only issue is that the adapters feel a little loose. Worried about about long term durability a little bit. Otherwise I am pleased so far.

Great device for devices. It will get the job done. I used it on a hot wheels track I converted to AC. It has circuit protection

Item as decsibed. Multiple adapters made easy to fit. Shipped fast

This thing can be a device saver if you are unsure of what you need. It very versatile. Its functions like it should and the adapters fit a wide range plugs.

It was just what we needed to go on our train set.

Works well, lots of adapters.

Excellent produit convient parfaitement à ce que je recherchais !!!

I measured the output voltage at various settings of the little rotary switch, and found it is pretty decent. At the 3v setting, it measures 3.52v. 5v -> 5.15v 7.5v -> 7.68v 12v -> 12.30v ---> not bad, quite acceptable for powering consumer electronic gear. I did a quick check of regulation when set for 12v. I connected a 2 watt automotive bulb I happened to have on my bench, and the output voltage only sagged by 0.05 volts. It has a tiny green LED on the front to indicate if it's getting power from the wall outlet. The set of various tips and adapters is very handy to have when you need to supply power to an unusual or obsolete piece of gear. Highly recommended.

Almost burnt down my Christmas tree... I used it to power the tree star at the top that runs on 2.4-3v... but the 3v on the adapter gave 3.5v (which I didn't measure beforehand...)... All other outputs are also "off", but in a certain acceptable range (e.g. 4.5v is 4.6v). In the morning, I plugged it in... and at some point in the afternoon, i could smell something "burning"... I noticed that the Star was turned off.. When I got near, the smell was worse, the adapter was barely touchable (hot) and the star was ruined... I unplugged everything and took measurements, and that's when I noticed the output voltage...

works perfect
