myVolts 20V 8.5A 170W AC Adapter for Lenovo ThinkPad P50 P51 P71

170 W AC adapter for ThinkPad P50 P51 P71

This 170 W AC adapter delivers 20 V at 8.5 A to Lenovo ThinkPad P50, P51 and P71 laptops. It accepts a universal 100–240 V input so it works worldwide with the included US power cord. The square yellow DC connector matches the original charging port on these mobile workstations. Over-current, over-voltage, short-circuit and total-power protection circuits guard the system during charging.

Square yellow connector fits original port

The square yellow DC plug inserts directly into the ThinkPad charging socket without adapters or converters. A single cable runs from the wall outlet to the brick, then a fixed lead reaches the laptop, freeing a second outlet for peripherals. The 100–240 V 50–60 Hz input range means the same unit travels between regions without a voltage switch. No internal battery is present; the unit only converts mains power for immediate use.

Protection circuits maintain output under load

Over-current, over-voltage, short-circuit and total-power safeguards activate automatically when the adapter sustains 170 W output for extended periods. The 2.5 A input rating at 100–240 V supplies enough headroom for continuous operation without thermal throttling. Output remains stable at 20 V 8.5 A during prolonged workstation workloads such as rendering or simulation. The unit is supplied new with a 30-day money-back period and a one-year service agreement.
