SUMMARY

The discussion confirms that using a 1.3A adapter instead of a 1.0A adapter for a device requiring 9V 1A output is safe and effective. The output current rating indicates the maximum current the adapter can supply, meaning the device will only draw what it needs, which is less than the adapter's capacity. The user successfully tested the Nintendo NES adapter, which has an output of 9V 1.3A, and found it functional for their device.

PREREQUISITES
  • Understanding of electrical specifications, particularly voltage and current ratings.
  • Familiarity with AC power supply standards, especially in European contexts.
  • Basic knowledge of how adapters function and their compatibility with devices.
  • Awareness of safety precautions when using electrical equipment.
NEXT STEPS
  • Research the specifications of various power adapters, focusing on output current ratings.
  • Learn about the implications of using adapters with different current ratings.
  • Explore safety guidelines for using electrical devices with non-standard adapters.
  • Investigate the availability of compatible adapters for specific devices in different regions.
USEFUL FOR

This discussion is beneficial for electronics enthusiasts, DIY repair technicians, and anyone troubleshooting power supply issues for devices requiring specific adapter specifications.

[SOLVED] 1.0 or 1.3A adapter problems?

Hi everyone!

I didn't know where to post this question so I posted it here.

I have a unit that needs an adapter with the following stats:

INPUT AC 220V 50Hz 17W
OUTPUT AC 9V 1A

It is completely impossible for me to find such an adapter. I've searched everywhere, and I even talked to electricians about it. They are very rare with European plugs (I live in Denmark), I don't even know if they exists..

BUT today I found an adapter from an old Nintendo machine in my house. It is ALMOST the adapter that I need. Here is the stats:

INPUT AC 220V 50Hz 17W
OUTPUT AC 9V 1.3A

As you can see the only difference is that the one I need has an 1A output and the one I found has a 1.3A output.

Is it possible to use a 1.3A adapter instead of the 1.0A? I've tried it quickly and the unit works with it, but I quickly turned it off again because I wanted to know if it was OK to use.

Hope you can help, I'm so tired of this problem.

Thanks!

Yes, the adapter you have found will work fine. The output current rating is a maximum, so as long as the current drawn is less than that maximum, it will work fine. Good find!

Thank you very much for your answer, I am very happy to hear that! Yeah I was very lucky that I found that Nintendo adapter (NES)!

Cheers
