Lenovo 135W ADL135NDC3A Power Adapter Charger – 20V 6.75A Square Slim Tip

The Lenovo ADL135NDC3A is a 135W laptop AC power adapter for compatible Lenovo laptops that require a 20V @ 6.75A power supply with a square Slim Tip connector (centre pin).

Maximum rated output is 135W so it's intended as a replacement power supply for laptops that are the same in terms of their electrical specs and connector type. Before you go ahead and buy it, check the part number on your existing charger and make sure your laptop is compatible with the voltage, wattage and square pin connector of this adapter.

A compatible power cable is included so you don't need to buy a separate cable for the supplied set. If you do require a replacement US, UK or European power cable then please just let us know when you place your order.

Product specs may vary slightly from batch to batch. Minor variations in appearance or packaging won't necessarily have any impact on the functionality but the adapter's electrical specs and connector must match your laptop.
