Works as advertised and the price is fair for a 90w laptop power adapter. The tips are a bit larger than a standard socket (which makes sense since they are actually two sockets plus a resistor) but not so big that they are a problem and they hold up very well. It supports both my Lenovo T570 (work) and HP Specter x360 (personal) laptops; I don't have to carry around two power adapters and the 90W is actually more powerful than the power adapters that come with laptops. The reason I'm giving it 4 stars instead of 5 is because there isn't a good way to carry around multiple power adapters. Hints... it would be very helpful if there was a way to attach a hint or two (or three) to the building block so that you don't lose the hints you actually use. I've put velcro (well, double 3M) on the bricks and grommets I use, but it's not as secure as I'd like it to be. Unfortunately, I can't find any adapters with this function, which I think would be obvious. Я получил это несколько дней назад (2018-05-03), поэтому я не могу комментировать долговечность… обновлю свой обзор, если он умрет, до тех пор он либо все еще работает, либо я больше не использую его регулярно и не понял, что he died.
