Power adapter Akyga AK-ND-29 90W 20V 4.5A for Lenovo laptops, AC 100–250V, 1.2m cable, black

Akyga AK-ND-29 is a dedicated notebook power adapter supplying 20V at 4.5A (90W) with a square yellow connector compatible with many Lenovo laptops. The adapter has an ABS housing, a 1.2 m cable and compact dimensions (49 mm × 114 mm). It meets CE, FCC, RoHS and REACH regulations and is delivered in an environmentally friendly EcoBox.

Advantages

The adapter includes a ferrite core on the cable to reduce high-frequency interference and mode currents. Built-in protections — OVP (over-voltage), OTP (over-temperature), OPP (over-power), SCP (short-circuit) and OCP (over-current) — ensure stable and safe operation for both the laptop and the power supply. Soft-start technology limits inrush current at startup, protecting connected equipment.

How to use

Connect the adapter to a mains outlet within the specified input range (100–250V), then plug the square yellow connector into the laptop power socket. Ensure the laptop supports 20V/4.5A and the connector matches before use. When not in use, disconnect the adapter from the mains and the device to reduce wear and save energy.

Recommendations

Use the adapter in dry, well-ventilated environments and avoid covering it during operation. Inspect the cable and connector periodically for damage and replace the adapter if any protective functions appear compromised. Store the adapter in the supplied EcoBox when transporting or not in use.
