From what I've noticed, the 3rd party ones don't have a UL logo on them.

My adapter has a UL logo on it and it is a 3rd party adapter. Bought it online for like $8 shipped and it has worked great now for 4 months! Never gets hot and I have tested it to be stable at 19.5v under heavy load (little under the 20v it should be, but good enough).

A lot of cheap adapters have labels identical to Lenovo. Even though I have no real knowledge, my guess is that they are aftermarket.

If it has a UL logo on it, and has actually gone though Underwriters Laboratory testing, then it probably is a quality unit, even though it's aftermarket. Falsely printing a UL logo on your product will get you in A LOT of trouble.

Only if UL can find/catch the vendor and manufacturer.
The presence on regulatory standards marks on "to-good-to be-true" priced items is, unfortunately, no indication that they actually comply with the relevent regulations (etc).

Most of the ones I have seen that are really cheap with "real-looking" lablels come from China. The power cord (from the adapter to the wall) is sort-of crumby. (crumby is a technical term) I think if pirates put Lenovo labls on, they don't really care about UL certification.
