It's a 12V unit using a 9V adapter. It could damage the adapter if it draws too much, or it might not function properly.
Ensure you use the correct converter. Differences in voltage indicate a mismatch.
It stays stable as long as the device gets enough current; too much will force a restart or power cut. It won’t harm the unit, but rebooting or shutting down signals the issue. Aim for a voltage rating that matches or is lower than the current—higher current isn’t critical.
