Purpose and audience

Build integration

The unit accepts 100-240V~0.5A at 50-60Hz input so it works on mains worldwide without a voltage selector. A power cord is included for domestic purchases; overseas orders receive the adapter only. The barrel connector mates directly with the target devices, freeing the user from hunting for a matching tip.

Rated at 18W output, the adapter runs cool enough for desk-top use with no audible fan. Internal protection circuits guard against incorrect voltage, short circuit and internal overheating during normal operation.
