Ideal as a primary or replacement adapter

Suitable for home, office, and travel – a practical solution when you want to keep a Dell laptop power adapter always within reach.

Safe operation thanks to built-in protections

Protection against overvoltage/undervoltage, overload, short circuit, and overheating helps protect both the adapter and your laptop during everyday use.

4.5 × 3.0 mm connector with pin for compatible Dell models

The correct tip type is essential for trouble-free connection. This adapter uses a DC barrel connector 4.5 × 3.0 mm with pin.

The Qoltec power adapter is designed for selected Dell laptop models and is ideal when you need a second power supply for work, travel, or as a replacement for the original. Quality workmanship and efficient electronics help ensure stable performance and low energy consumption.

Safety is crucial when powering a laptop – the adapter is made from quality materials and is equipped with protections that safeguard both the adapter and the powered device:

protection against too low or too high input voltage,
protection against overload,
protection against short circuit,
protection against overheating (e.g., under overload or reduced airflow).

When choosing an adapter, we recommend checking the parameters on the laptop label: power (W), voltage (V), and current (A). Power and current on a new adapter can be the same or higher; the voltage should match (a deviation of about ±0.5 V is commonly tolerated). A matching connector is also essential – here 4.5 × 3.0 mm with pin.
