The Qoltec 51775 40W Black power adapter delivers a stable 40-watt output intended for powering monitors and similar portable devices. Designed for use with mains voltages of 220–240 V and a frequency of 50/60 Hz, this compact adapter combines consistent electrical performance with a simple black housing. Its 1.75 m cable provides flexible placement options for home or office setups while the small footprint helps save space on a desk or behind equipment.

Advantages

This adapter offers a reliable 40W continuous output that suits many monitor models, ensuring steady power delivery during regular operation. The wide input range of 220–240 V and dual-frequency support (50/60 Hz) make the unit compatible with standard European mains supplies. A 1.75 m integrated cable increases placement flexibility without requiring immediate proximity to a wall socket. The compact physical dimensions—88 mm in width and 35 mm in depth—minimize occupied space and simplify installation in constrained environments. The black finish provides a neutral appearance that blends with most office and home electronics.

Suitable for

• Powering computer monitors that require up to 40 W
