How to use

Confirm that the device to be powered accepts a 19 V DC input and uses a compatible 5‑pin plug before connecting. With the adapter unplugged from mains, insert the 5‑pin connector into the device’s DC input socket until it seats securely. Then connect the adapter to a mains outlet using the supplied cable or an appropriate mains lead. Power the device on following its normal procedure. When disconnecting, switch off the device first if possible, unplug the adapter from the mains, and then remove the DC connector from the device.

Usage recommendations

Use the adapter indoors in a dry, ventilated location and avoid covering it to prevent overheating. Ensure the mains lead and connector are intact and secure; do not use if cables are damaged. Match the adapter’s voltage and connector type exactly to the device’s requirements to prevent damage. For extended continuous operation, allow occasional cooldown periods and follow the equipment manufacturer’s guidance on external power supplies.
