Lenovo 45W USB-C Adapter — Genuine Original Replacement Charger for ThinkPad India

The Lenovo 45W USB-C adapter is the lightest and most portable charger in Lenovo’s standard ThinkPad adapter range. Weighing under 200g and compact enough to drop into a shirt pocket, it is the go-to charger for Indian ThinkPad X1 Carbon, X1 Yoga, X270, T470, and T570 users who travel frequently between office, home, and client sites. Unlike the heavier 65W adapter, the 45W version prioritises portability without compromising charging integrity — delivering certified Smart Voltage Power Delivery (PD) output that protects your ThinkPad battery and motherboard on every charge. Explore our full range of Lenovo products at Thencix including laptops, accessories, and spare parts for ThinkPad series.

Smart Voltage Technology — Certified Precision Charging for Your ThinkPad

The Lenovo 45W USB-C adapter uses Smart Voltage Power Delivery (PD) technology — the same certified charging intelligence built into every genuine Lenovo adapter. It automatically detects the voltage your connected device requires and delivers precisely 5V/2A, 9V/2A, 15V/3A, or 20V/2.25A accordingly. This real-time voltage negotiation protects your ThinkPad battery cells from overcharging damage and ensures the motherboard receives a stable, regulated power supply on every use.

Third-party compatible chargers available on Amazon India and Flipkart at lower prices do not carry Lenovo’s Smart Voltage certification. They may deliver a fixed output regardless of what your ThinkPad actually requires — a risk that accumulates as battery cycles add up. For a ThinkPad worth ?70,000–?1,50,000+, the ?500–?800 difference between genuine and compatible is not a meaningful trade-off. The Lenovo 4X20M26258 is tested and backed by a 1-year manufacturer warranty. The adapter is also universal voltage rated — AC input of 100–240V at 50/60 Hz works on all Indian power sockets with no converter required.

45W vs 65W Lenovo Adapter — Which One Do You Need?

This is the most common question from Indian ThinkPad buyers replacing their charger. Here is the clear answer:

Choose the Lenovo 45W adapter (4X20M26258) if: Your ThinkPad is from the X series (X270, X280, X390, X13), X1 Carbon (5th/6th Gen), X1 Yoga (2nd/3rd Gen), X1 Tablet, ThinkPad 13, T470, T470s, T570, P51s, or Yoga 370. These are lighter, thinner ThinkPad models with lower power requirements. The 45W adapter matches their design intent and is sufficient for full charging even under moderate workloads.

Choose the Lenovo 65W adapter (4X20M26274) if: Your ThinkPad is from the T480, T490, T14, T15, E14, E15, L14, L15, or any newer-generation ThinkPad released after 2018. These models have more powerful processors and larger batteries that benefit from the higher 65W output for faster charging under load. If in doubt about which adapter is correct for your specific ThinkPad model, WhatsApp us at +91 98911 50949 with your model number and our team will confirm before you order.

Important: Using a 45W adapter on a ThinkPad that ships with a 65W adapter is generally safe — the laptop will charge, though potentially more slowly under heavy load. However, always verify your model’s minimum adapter requirement before purchasing. Thencix stocks both Lenovo adapter wattages for the full ThinkPad range.
