– Yes, they are likely interchangeable even though voltage is not the same. This is because the voltage difference is within specs, and I am GUESSING you could go even higher or lower in voltage.
Is it safe to use a lower rated PRI adapter?
Pri: 230V-240V ~50Hz. As this is lower rated and works is it safe to use or have I got it all around the wrong way and it is unsafe to use because it is a lower rating? I can’t seem to find any replacement adapter to buy that matches the old one. Your are right, the replacement part is not strong enough.
