Spitz X-3000 use a power adapter with a barrel of 5.5*2.5mm instead of 2.1mm

I have an adapter with the correct voltage and amperage but the barrel interior diameter is 2.5mm instead of the 2.1mm of the original power adapter, can I safely use it? I am worry of false contact or loose connection, thanks

2.5mm is ok,you can try it.
The risk of false contact or loose connection is not high.

It works great with 2.5mm, thank you
