This charger remains one of the fastest on the market because it has a power output of up to 1550mAh / 3V to 10W knowing that other chargers is at 300mAh / 2.8V for 6 W. Resulting in much faster load, can count one less than an hour to charge 2 AA or AAA battery 1300mAh to 750mAh. But the big advantage is still the possibility of an extra load in 60 minutes to 4 1300mAh capacity battery. Warning indicated time will not be the same if you are loading high capacity batteries such as those of 2500 mAh but you divide your load time by 4.
Electrical consumption at this charger remains economical compared to other due to the reduced charge time and gets a very good yield.
Negative: It emits a faint sound so do not charge the night next to you. The batteries are quickly warm because of the power consumption in a minimum of time.
Conclusion: Charger not to be missed especially with reductions in the time.
