Laptop Power Adapter Akyga AK-ND-12 90W 19V 4.74A AC-to-DC, 100–250V input, black

Akyga AK-ND-12 is a dedicated 90W notebook power adapter supplying 19V at 4.74A with a 5.5×1.7 mm plug. The adapter is intended for indoor use and features a wide input range of 100–250V, a 1.2 m cable and a compact ABS housing (56 mm × 131.5 mm). It is certified to CE, FCC, RoHS and REACH standards and comes in black with a net weight of 0.244 kg.

Advantages

The power adapter includes a ferrite core on the output cord to reduce high-frequency interference and mode currents. Multiple built-in protections (OVP, OTP, OPP, SCP and OCP) and soft-start technology ensure stable, safe power delivery and protect both the laptop and the adapter from electrical faults.

Suitable for

• Laptops and notebooks requiring 19V/4.74A power
• Replacement or spare adapter for compatible laptops with 5.5×1.7 mm barrel plug
• Indoor use where a compact, certified 90W adapter is needed

How to use

Connect the adapter to an AC mains outlet within the specified input range (100–250V), then plug the 5.5×1.7 mm connector into the laptop power socket. Ensure the polarity and connector size match the laptop requirements before powering on. Allow the adapter to reach operating conditions after initial connection; soft-start circuitry mitigates inrush current during startup.

Recommendations

Use the adapter indoors and avoid exposure to moisture or extreme temperatures. Verify compatibility with your laptop model (19V/4.74A and 5.5×1.7 mm plug) before use. Unplug the adapter during extended periods of non-use and inspect the cable and connector regularly for damage.
