170 W 20 V power supply with 10 ft cord and overload, over-voltage and short-circuit protection for compatible Lenovo all-in-one PCs

  • World-wide 100-240 V input works anywhere
  • 170 W at 20 V powers compatible Lenovo AIOs
  • 10 ft total cord length gives flexible placement
  • FCC, CE and RoHS certified for safety
  • Over-current, over-voltage, short-circuit and total-power protection included

Replacement 170W Adapter for Lenovo AIO

This 170 watt AC/DC adapter replaces the original power supply for Lenovo all-in-one models including the C440, C540, A520, C300, 3012, C305, B31R2, 892, C315 and 4022. It delivers 20 volts DC from a worldwide 100 to 240 volt AC input at 50 or 60 hertz. The unit ships new with a total power cord length of 10 feet.

Upgrading from a Failed or Lost Original Charger

The adapter is a direct replacement when the factory charger fails, is lost or shows signs of cable wear. It matches the original 170 watt rating and 20 volt output so the all-in-one receives the same power envelope without modification. The jump is worth it when the original unit no longer holds a stable connection or trips its internal protection circuits.

Capacity and Headroom for All-in-One Workloads

The 170 watt capacity comfortably handles the CPU, integrated graphics, display panel and peripheral ports of the listed Lenovo AIO systems under typical office and home workloads. Safety circuitry includes over current, over voltage, short circuit and total power protection plus overheating guard with a smart chip. It is not suited for systems that require a higher wattage rating or a different voltage rail.

Questions about this item

What connector and cable length does the 170W 20V adapter use for Lenovo AIO models like the C440?

The adapter provides a 20V DC output through a 10 ft total power cord designed for the listed all-in-one PCs.

How do I install the replacement adapter, and what step is often missed?

Connect the AC plug to a 100-240V 50/60Hz mains socket, then attach the DC connector to the AIO; the step often missed is verifying the outlet voltage range before plugging in.

What maintenance or replacement should I expect for this power supply over time?

The unit includes over-current, over-voltage, short-circuit and thermal protections; if the smart chip or isolation materials degrade after extended use, the full adapter would need replacement.
