This is my third unit on my 4.5 year old Dell laptop. My newest 4mm connector at the insertion point, same as original equipment. This new one is perfect. Original replacement device. However, my previous second charger/plug, which I ordered just last year, may have been a different brand. Thought I'd buy an upgrade on the original which has frayed wires at the connector. The vendor drew a device that shows a "good" 90 degree offset with less torque on the connector that goes into the base of the laptop. What was sent was another straight connector and a 6mm connector protruding from the laptop. It just made more torque and stopped charging after a year. Moral of the story: be careful when replacing original equipment! It could be fake.
