The Akyga® AK-ND-C12 USB-C adapter is a practical accessory for older Lenovo laptop models. Allows you to charge a laptop with a 7.9x5.5mm connector with a USB-C PD charger. So if you lose or damage your old power adapter, you can replace it with a new universal USB-C power adapter. This way, we can charge almost all electronic devices with a single charger. This greatly simplifies the daily use of the devices and saves space in your backpack or bag when traveling.
