AC Adapter Lenovo 45W Type-C USB 5A10W86246 — 45W USB-C laptop charger

The Lenovo 45W Type-C USB AC adapter (45W USB-C laptop charger) is a compact external power supply that delivers up to 45 watts of power through a USB‑C output for compatible Lenovo laptops and USB‑C devices. Designed for everyday charging at home, in the office or while traveling, this adapter uses USB Power Delivery (PD) protocol to negotiate the appropriate voltage and current with PD‑capable devices. The compact form factor and integrated plug options make it convenient to carry and easy to connect for plug‑and‑play use.

Advantages

This 45W USB‑C adapter provides stable power delivery to charge laptops and peripherals efficiently, while its small size reduces carry weight and occupies minimal desk space. The USB‑C connector supports reversible insertion, simplifying connection in low‑light or cramped conditions. Built‑in safety features protect against overcurrent, overvoltage and short circuits to help preserve battery and device longevity. The adapter is compatible with a range of USB‑C PD devices, enabling a single charger to serve multiple products.

Suitable for

• Charging compatible Lenovo laptops and ultrabooks that accept up to 45W via USB‑C
• Powering tablets, smartphones and USB‑C peripherals that support USB Power Delivery

How to use

Connect the adapter to an AC outlet using the integrated plug or detachable cable as applicable, then insert the USB‑C connector into the device’s USB‑C charging port. The adapter and connected device will negotiate the appropriate PD voltage and current automatically; charging begins once the handshake completes. For best results, use a high‑quality USB‑C cable rated for power delivery. Disconnect the charger when the device is fully charged or if the adapter becomes unusually hot or emits unusual noises.

Recommendations

Use the adapter with USB‑C PD‑compatible devices only and avoid using damaged cables. For optimal charging speed and device safety, pair the adapter with a USB‑C cable rated for the required amperage and minimize simultaneous high‑power accessory usage while charging.
