Works well! Bought this as a travel charger for my Chromebook so as not to have to carry around the bulky AC power adaptor. No problems getting 45 Watts for charging. Good quality build, the spring for the folding prongs holds firmly. Still early days, but if this charger is like the others I have from PrimeCables, it should last a long time. One thing...it's advertised as 'transparent'...however, it is all white...which is actually a good thing...;) ! Recommend.
