This is a power adapter. It's nothing fancy, it's not rocket science, it converts wall power into DC for laptop use. Nevertheless, he does his job well. We bought an Inspiron 15 at public auction, but it didn't have a cable. The laptop had a USB-C port to charge it from, but it required a 90W power adapter and the best we found that day was a 65W source. So I just ordered them (two of them because I _always_ order an extra laptop power supply) and they worked like magic. The power cord is actually longer than I expected (hence the 5th star) which was a bonus. It wasn't the cheapest offering, but it turned out to be the most reliable and affordable. Even arrived a day earlier than expected which was amazing.
