The cords and case of this unit feel sturdy with big molded plugs on wires with thick insulation.I like that a velcro cable tie is included on both the ac side and the usb c side. There is also a plastic wire clip on the usb c side. This makes it very nice to store.I also was impressed that the charger will time out if left plugged in without charging anything for around 2 days. This is a great safety feature that should also help with longetivity.I hooked the charger up to a usb c tester to see if the values looked correct. It easily put out the 65 watts my laptop needed to run and charge. The voltage also seemed to be within a healthy range.The one negative thing I noticed with this charger is it makes some very light high pitched noises from inside the case. This isn't unusual for chargers but this one is louder than most. It doesn't really bother me as I can only hear it late at night when everything is quiet.Overall, this is a budget focused charger that worked well with my lattitude 7400. It does not get much better at this price range.
