12V 0.5A 500mA Power Supply AC 100~240V to DC 12V 500mA 6W Adapter 12V 0.5A Transformer for CCTV Surveillance System LED Strip Light with 5.5 x 2.5mm 2.1mm Center Positive Tip

This 12V power supply is excellent! Works perfectly for my electronic devices. The 0.5A 500mA output is exactly what I needed. The AC 100-240V input makes it perfect for travel and universal use. The build quality is solid and reliable. The cable length is generous and the connector fits snugly. No overheating issues even after extended use. Very quiet operation with no buzzing sounds. Great value for money. The transformer is well-made and durable. Perfect replacement for my original adapter. Highly recommend this power supply!

It fulfills its purpose. I needed it to connect some computer speakers and it works perfectly.

Got tired of replacing the batteries in my Omlet automatic chicken door. This has the same power input and output but the cord is a little shorter. Not a problem for my setup and it works great with their door controller. No more batteries needed!

It worked great

I needed to return this item due to not working in the stick vacuum. I do not believe this item was the reason the vacuum was not charging though.

Thus was a great replacement for a failed charger/power supply

Works great fyi the plug it came with fit right in my radio shack scanner polarity was correct and everything I was ready to splice in a new plug but didn't even have to and I was happy to find out it didn't throw any noise into the radio like switching supplies sometimes can

The old Power adapter for my SWR, power meter was getting pretty hot in use For a period of time and I did not trust it anymore This Power adapter does what it's supposed to do powers the meter And only gets a little warm during long periods
