Product Description
Power your Lenovo laptop with stable, high-performance current using the Lenovo 90W AC Power Adapter (20V 4.5A, 7.9×5.5 mm pin-inside tip) — a robust and reliable charger built for ThinkPad, IdeaPad, and other Lenovo laptops that require this output and connector type. With a generous 90-watt output, this adapter is ideal for heavier workloads such as multitasking, programming, content creation, and day-long work sessions without battery drain worries.
The adapter features a 7.9 mm × 5.5 mm pin-inside round connector (often called the “big-port” connector), ensuring secure connection and compatibility with many Lenovo models shipped with similar stock adapters. It includes a full AC power cord (3-prong) and supports a universal AC input of 100–240V, 50–60Hz, which means it works reliably in Bangladesh and abroad — no voltage converter required.
Built with quality internal components and tested output, this adapter delivers clean, stable power while protecting your laptop from electrical hazards. It includes built-in safeguards against over-voltage, over-current, overheating, and short-circuit — critical protections given Bangladesh’s sometimes unstable electricity supply.
Whether you’re replacing a lost charger, upgrading to a more powerful unit, or keeping a spare for travel and office use, this 90W adapter is a dependable choice for Lenovo users. And with 12-month warranty support from LAPTOPVAI, your purchase is backed by after-sales assurance.
