The supplier also notes overload protection, overcharge and overdischarge protection, overheating protection with a smart chip and anti-interference isolation materials. These features aim to protect both the adapter and the connected device.

Questions about this item

How long is the power cord so I know if I will need an extension lead later?

The AC adapter includes a 10 ft power cord, giving plenty of reach for most desk or wall sockets without an extra lead.

What is the maximum input voltage the adapter can handle before it stops protecting the laptop?

The unit accepts a worldwide input range of 100-240 VAC at 50/60 Hz, so it will operate safely on any standard mains supply within that window.

Does the adapter run hot or make fan noise when it is left charging all day?

The adapter has no fan; it relies on passive cooling and built-in overheating protection with a smart chip to stay safe during continuous use.
