45W USB-Pin AC Adapter

The myVolts 45W USB-Pin AC Adapter replaces a lost or damaged Lenovo power supply for ThinkPad, ideapad and other listed models. It delivers 20V at 2.25A through a USB connector with a centre pin. The unit accepts 100-240V input for worldwide use.

Replacing an original Lenovo charger

This adapter matches the 45W output specified for many ThinkPad X, T, E, L and Yoga series laptops as well as numerous ideapad and Lenovo branded models. It is worth the switch when the factory brick fails, the cable frays or a spare is needed for travel. Buyers whose laptops require a higher wattage rating or a different connector shape cannot use this unit.

Limits of the USB-Pin interface

The fixed 20V 2.25A output suits only devices designed for that exact voltage and current. Laptops that negotiate higher power over USB-C Power Delivery will not charge at full speed. The barrel-style pin connector prevents use with modern USB-C only ports. No other voltage or current options are provided.

Questions about this item

What connector type does the 45W adapter use for the laptop side?

It uses a USB connector with a centre pin that fits the rectangular charging port on supported Lenovo models.

How do you connect the adapter to mains power and what is the common mistake?

Plug the supplied power cord into the adapter’s IEC inlet then into a 100-240 V socket; the mistake is forcing the USB-pin tip upside-down instead of aligning the pin with the port’s centre hole.

Which parts may need replacement after extended use?

The detachable power cord and the USB-pin cable can wear at the strain reliefs; both are standard IEC C7 and USB-pin items you can swap separately.
