Tips and FAQs:

1. If your device's DC IN voltage is not in the options, please select the closest one. For example, if you device needs 5.5V, you can choose 5V or 6V. 7.9v you can select 7.5v.

2. It is a Center Positive + power supply. Please kindly check what polarity of your device before bidding. You can find the polarity information printed beside the power port.

3. If your device needs a Center Negative - power adapter, please kindly don't forget to buy one Belker Polarity Reversed Cable together. The wrong polarity may cause some damage to your device.

4. For AC to DC Power Adapter, normally, bigger one can be compatible with smaller one. For example, 5v 1a works with 5v 0.5a, 12v 1a works with 12v 0.8a. Conversely, NO. So please use it under 12W.

How to use correctly:

1. Check the AC adapter's DC output parameters and your device's DC in parameters. Please make sure they can be matched well.

2. Connect the correct adapter tip and make sure that it's firmly attached to the dc input port of your device.

3. Set the right DC output voltage which is corresponding to dc12v dc9v dc7.5v dc6v dc5v dc4.5v dc3v switch position.

4. Connect the adapter to the electrical receptacle and powering your devices.

I burned some of the diodes in my treasured ‘Welcome to FABULOUS Las Vegas’ sign by trying to run it off a 5 Volt adapter (instead of the 4.5 Volts the thing needed).I bought another sign (on eBay) and this kit, which includes a 4.5 Volt setting, among others.Lo and behold….The only reason it gets 4 stars instead of 5 is because I had to trim back some of the plastic insulation around the plug for the type connector my sign needed with a knife to get it to fit in the receptacle.Otherwise, it works fine.

5.0 out of 5 stars Perfect Charging Solution
Reviewed in the United States on November 22, 2023
Had this music box for years, but lost the plug about 7 years ago so it sat unused every Christmas. I decided that the plug was never going to magically reappear, so I checked Prime and saw many different options. This one seemed very versatile and had really good reviews. It showed up the next morning and I quickly found that it was a perfect solution!

It was nice to finally get to play it for my granddaughter. I highly recommend this product!!
