Lenovo Laptop Charger 20V 4.5A 90W - DC 7.9x5.5mm, Overload Protection

Keep your Lenovo laptop powered and protected with this original-spec 90W charger. Delivering a steady 20V at 4.5A, this replacement power adapter is built to match Lenovo's official output specifications, giving you reliable charging without compromising your battery or motherboard. It connects via the 7.9 x 5.5mm barrel connector found on a wide range of Lenovo ThinkPad and IdeaPad models, making it a straightforward swap for a lost, damaged or ageing original charger.
