I still have the Powerline 4 Pro charger that in my opinion for charging AA and AAA cells is more appropriate. In addition, you can see in plain language what the charger makes and how much of the charge current. The capacity can be seen there as well and it has a USB port and a car charger. All this I miss in this charger. Here, however, the total flow separation after the end of one hour should be emphasized. It can also invite Baby and Mono cells. Unfortunately, even here the trickle charge ends after charging is completed after an hour because of the automatic shutoff feature. But saving power is not correct trickle charge. Otherwise Agree emphfehlen.
