3 V 1 A AC adapter for low-power devices

This compact power supply converts 100 V to 240 V mains input into a regulated 3 V DC output rated at 1 A and 3 W maximum. It is intended for LED light strings, mini fans, routers, CCTV cameras, Bluetooth speakers and similar equipment that draws 3 W or less. The barrel connector measures 5.5 mm by 2.5 mm and also fits 2.1 mm centre pins.

Check voltage polarity and current draw before use

Verify that the target device requires exactly 3 V DC with centre-positive polarity and a current demand no greater than 1 A. The adapter accepts 50 Hz or 60 Hz mains frequencies worldwide. Ensure the barrel jack on your equipment matches the 5.5 mm outer diameter and either 2.5 mm or 2.1 mm inner diameter.

Flame-retardant shell rated to 1382

The housing uses flame-retardant material tested to 1382 and carries FCC, CE, RoHS and CCC certification. Built-in safeguards include overcurrent, overvoltage, overload and short-circuit protection for stable operation. A fixed power cord approximately 3 ft long keeps the adapter close to the outlet while the barrel plug connects securely to the device.
