This is an easy to use AAA/AA battery charger, capable of charging up to 16 batteries simultaneously. The charging process is easy: simply power up the charger and insert the batteries. Once the batteries are charged, the unit detects it and stops the charging process automatically. Its biggest trade-off is the inability to charge Li-Ion batteries.
Pro Simple and informative interface
The interface consists of two large LCD screens and a refresh button. The LCD screens show the current status of each individual battery, whether they're charging/discharging or if the battery is already fully charged. The 'Refresh' button activates the refresh charging cycle (the batteries are fully discharged, before charging begins).
Pro It knows when to stop charging
This charger automatically detects the end of the charging process by measuring battery temperature. Once the battery hits the ‘perfect spot’, when it’s already fully charged, yet not overcharged, the temperature of the battery increases. This temperature increase signals the charger that the charging process is complete.
Con It cannot do fast charging
There's no way to change the charging current of this unit, therefore it's not good for situations where you need to charge a battery in 1 or 2 hours, which could be done by applying a high charging current. The charging currents for AA and AAA batteries are set to 500 mA and 250 mA correspondingly. Even though these currents are adequate, it will take approximately 4 hours to charge approximately 4 hours to charge a standard 2000 mAh AA battery or a standard 1000 mAh AAA battery.
