I bought 2 adapter for the lenovo x1 laptop. Unfortunately only one operates normally, 2nd adapter completely bad.
Highly recommended, however for phones it charges slow.
However, certain devices, such as my mobile phone will not charge
worked as advertised
I bought this so that I could utilise an old power unit as a spare to keep in my travel bag 'just in case'. I have used it a number of times now with no issue. It looks and feels well made with a good quality metal casing - aluminimum I assume - that adds to the view that this is a robust product and all for a very fair price.
