65W USB Square Tip AC Adapter

This 65W AC adapter delivers 20V at 3.25A through a USB square yellow tip connector. It replaces Lenovo ThinkPad and Yoga chargers across T, X, L, E, S, Z, G, B and V series laptops. The unit accepts 100-240V input at 50/60 Hz and includes short circuit protection. It is also compatible with 45W models requiring 20V 2.25A.

Plug-in installation with tip verification

Connection is straightforward: attach the square yellow tip to the laptop power port and plug the cord into a mains outlet. The adapter is corded electric with a fixed cable, so no separate cable is required. The most common issue is ordering this square tip when the laptop needs a USB-C charging tip instead. Confirm the port shape before purchase.

Check your laptop model and connector type

Verify that your device appears in the supported ThinkPad T, X, L, E, S, Z, G, B, V or Yoga series lists. Ensure the original charger uses a USB square yellow tip, not a USB-C connector. Match the output specification of 20V 3.25A or 20V 2.25A to your laptop's requirement. The adapter weighs 0.5 pounds and measures 14.33in W x 12.83in H x 9.06in D.

Questions about this item

How can I confirm the adapter is delivering 20V and 3.25A after plugging it in?

The charger LED will illuminate and the laptop battery icon will show charging; a USB multimeter on the output can verify 20V and 3.25A.

What comes in the box and do I need a separate mains cable?

The package includes the 65W adapter with fixed square yellow tip and an integrated AC cord; no extra mains cable is required.

Should I choose this 65W model or the 45W version for my ThinkPad T470?

This 65W unit (20V 3.25A) also supports 45W (20V 2.25A) devices, so it covers both power levels for the T470.
