Behaviour under sustained load

The adapter is rated for continuous operation at its full 65 W output without derating. Internal protection circuits guard against over-voltage, over-current and short-circuit conditions during prolonged use. Thermal design keeps the enclosure within safe limits when delivering maximum current for extended periods. No active cooling is employed, so adequate airflow around the brick is expected.
