24W 3V 4.5V 5V 6V 7.5V 9V 12V Universal AC/DC Adapter Multi-Voltage Regulated Switching Power Supply with 8 Round DC Plugs for LED Strip Light CCTV Camera Speaker Router,2A Max

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

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.

Needed an adaptor for a portable CD player. Lots of voltage and plug choices. Works great.

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.

This unit is excellent with variable output and really ideal for small battery /low voltage lights. Disconnect the battery box, use one of the supplied connectors, set the required voltage ( 1.5 volts per AA or AAA battery. 2 batteries equals 3 volts, 3 cells equals 4.5 volts. ) and plug in. No more battery issues.

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

I needed this to slow way down a record cleaning rotating device. Works well and is inexpensive

It's ok for price. Cord is a bit thin wondering if it will last

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...

This power supply works great with all my devices. It’s easy to adjust the voltage and delivers steady power without overheating. Perfect for LED lights, cameras, and more. Solid build and very dependable.
