I wanted a compact charger with 100-240V worldwide voltage. My original preference was Sony BCG-34HD4. I was attracted by the word of 90-minute quick charger. Kind of regret after received the package:- It comes with a power cord. Not a flip-out plug like other compact charger.- It will NOT stop charging when you put a fully charged Battery in.- The charging time is much higher than 90-minute.From the user manual,NiMH AA 2100 mAh (1-2 batt. 105 min. & 3-4 batt. 230 min.)NiMH AA 1850 mAh (1-2 batt. 95 min. & 3-4 batt. 215 min.)NiMH AAA 750 mAh (1-2 batt. 145 min.)I experienced even higher charging time.Should buy Sony BCG-34HD4.
