I wish they were a little bit cheaper and available in europe. Even an 12 year old Lenovo 90W round-plug powersupply to squared plug adapter to ELECJET USB-C USB-PD Adapter in chain worked hassle-free.
The devices recognise a 60W powersupply and adapt the charging speed according to that. Conclusio: everything works perfect, no problems.

But this ELECJET adaptor JUST WORKS FINE ! We have tested it with a Lenovo Thinkpad L480, a MacBook Pro 2017 and a Xiaomi A2 smartphone, a Google Pixel 3 smartphone and one Thunderbolt 3 to HDMI Adapter with USB-PD. I was concerned about compatibility because a have read many posts about problems with incompatible power supplies and cables. USB-PD is much more than just a mechanical adapter. It is convenient to have many power supplies, one for the desk, one at the meeting room and one at home. At latest generation notebooks USB-C with USB-PD is neccessary. Last time a plain mechanical adapter from round to angular shaped plug was sufficient. Every other generation the plug of the power supply changes. We do have a lot of Thinkpad Notebooks in our company. So, at least my experience with this ELECJET adapter is 5 stars.

I mentioned this to the other vendor, and after an exchange of messages, they gave me a full refund and told me that they were not going to keep selling those particular adapters anymore. The one I got from somewhere else (a generic, unbranded one), although supposedly had the same specs, when I connected it, my laptop immediately displayed a warning on the battery charging icon, something like "Weak charge detected". Well, I guess 60W is sufficient, because my T490 works perfectly, no complaints, as if it was its OEM power supply. This adapter's specs mention that it can be connected to a 65W or a 90W power supply (flat/slim/square tip), and the output from the USB-C side will be 60W. Some potential buyers may be wary because of the "60W" (60 watts) output thing, because it seems that Lenovo thinkpads usually require at least 65W. I have several (about 5 or 6) old Lenovo power supplies, maybe 1 or 2 IBM ones, some of them with round tips (already with flat tip adapters), and wanted a USB-C adapter so I could use them with my new Thinkpad T490. I'll edit and add more details or photos later, just wanted to submit a 5 star review now, because I'm happy to share that this adapter DOES WORK! (contrary to another one I got previously from a different vendor, different marketplace).
