Indoor charger Akyga AK-NU-12 for laptops, 65 W, output 1–3.5 V, input 18.5–20 V, AC, black

Akyga AK-NU-12 is a universal indoor charger for notebooks that supports output voltages of 18.5 V, 19 V, 19.5 V and 20 V with a maximum power of 65 W. The charger is supplied with a set of six interchangeable plugs that differ in inner and outer dimensions and presence of a centre pin, allowing compatibility with a wide range of laptop models from different manufacturers. The adapter cable includes a ferrite core to reduce high-frequency interference and mode currents.

Advantages

The AK-NU-12 automatically adjusts output voltage when a selected plug is connected and includes multiple protection circuits (OVP, OTP, OPP, SCP and OCP) for stable and safe operation of both the charger and the connected laptop. Soft-start technology reduces inrush current at power-up. The compact black design and a set of six tips make it convenient for home and office use without carrying multiple chargers.
