🌟 KEY ADVANTAGES

🔹 Genuine Lenovo adapter - the laptop correctly detects 90W, with no insufficient adapter warnings
🔹 Full 90W - models with a faster CPU or discrete graphics (e.g. T420, T520, T530) charge quickly even while working, with no CPU throttling
🔹 One adapter for many ThinkPad series - the same tip fits T60, T400, T420, X220, X230, L520 or Edge, so an office with several laptops needs only one charger type
🔹 Wide 100-240V input range - works in Poland and abroad
🔹 Tested before shipping - used adapter, tested, with a 6-month warranty
