This universal charger does its job. I have purchased other brands of univerdal chargers and this charger beats those other brands slightly. The connections switch very easily and secure better than the last brand I had used. Even so, they have a very ssnug fit and doesn't make me thinik that it might fall off, making me search the floor prior to my next charge. The digital display only displays the amount of voltage that the attached adapter willl allow. That same number that gets displayed on the transformer part is imprinted on the side of each plug. some plugs say 18V others say 20V, I had mistakenly thought that the LCD display might state what the exact current being sent out actually was at any given tie but that is not so. It also has a 5V 2.0 usb plug on the block part that suits as an extra charger for other devices. That simple extra port can be convient if you are not already using the universal charger at it's mximum length from the wall outlet. Perhaps even stilll that would be suitable for other devices to charge at the same time. All in all the price tag associated with this adapter and the quality it seems to have make this universal adapter my number 1 choice to recommend.
