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.<o:p>
The right AC adapter for your device is one with matching electrical ratings. The device's input voltage and current must match the adapter's output voltage and current. Check the device's product label or user manual to see its rated voltage and current.<o:p>
The device could power on, and just draw more current from the adapter than it's designed for. This could cause the adapter to overheat or fail. Or, the device may power on, but the adapter may not be able to keep up, causing the voltage to drop (see voltage too low above).<o:p>
AC adapter issues can occur due to a faulty AC adapter, faulty power cable, damage to the power or AC adapter cable , and so on.<o:p>
Power adapters can cost hundreds of dollars to replace, but they can often be repaired for free if you already have the necessary materials. The same thing can happen to the plug on any kind of power adapter, but it happens most frequently with notebook computer power supplies, especially ones with coaxial cords.<o:p>
