Lenovo 65W Round Tip Adapter – Official Charger for Older Lenovo Laptops The Lenovo round tip adapter (GX20K78591) is the correct replacement for older Lenovo laptops. It suits models with a round barrel-style power connector rather than the USB-C standard on newer devices. Many Lenovo IdeaPad and older ThinkPad models use this round tip connector. Using the official Lenovo adapter ensures the correct voltage and current are delivered to the laptop’s charging circuit. Third-party chargers with the correct plug shape do not always deliver the correct power profile. Using an unofficial adapter risks slow charging, failed charging under load, and potential battery degradation over time. The Lenovo round tip adapter is manufactured to the same specification as the original charger. It provides the same safe, reliable charging performance as the factory unit. Compatible with South African Power The Lenovo round tip adapter accepts 100 to 240V input. It is fully compatible with South African 220V power without a separate converter. The build quality reflects Lenovo’s original equipment standard. It is an ideal replacement for a lost, damaged, or worn-out charger, and works equally well as a spare unit to keep at a secondary location.
