Akyga power adapter AK-ND-50 for laptops, 20 V 2.25 A 45 W, connector 4.0×1.7 mm, 1.2 m cable, black

The Akyga AK-ND-50 is a 45W indoor power adapter for laptops and compatible portable devices. It accepts a wide input voltage range of 100–250V AC, delivers stable DC output through a 4.0 x 1.7 mm barrel connector, and is housed in black ABS synthetic material. The adapter offers a mean time between failures (MTBF) of 100,000 hours, a 1.2 m cable and compact dimensions of 49 mm width and 114 mm depth. It meets RoHS requirements and holds CE, FCC and REACH certifications.

Advantages

The adapter combines a compact form factor with industry-standard safety and material certifications, providing compatibility across varying mains voltages and meeting common regulatory standards. Its ABS casing and specified MTBF indicate durability for regular indoor use. The 4.0 x 1.7 mm connector and 45W output make it suitable for many laptops and devices that require a similar power profile, while the 1.2 m cable length balances reach and portability.

How to use

Confirm that your device accepts a 4.0 x 1.7 mm barrel connector and that its required power does not exceed 45W. Connect the adapter to the mains socket within the 100–250V range, then insert the barrel connector into the device power inlet until it seats securely. Use the adapter on a stable, dry surface and avoid placing heavy objects on the cable or transformer body. Disconnect from mains before cleaning or when not in use for extended periods.

Recommendations

Use the adapter only with devices that match the connector size and power requirements. Ensure adequate ventilation around the adapter during operation and avoid exposure to liquids or extreme temperatures. For long-term reliability, inspect the cable and connector periodically for wear and replace the adapter if any damage or abnormal heating is detected.
