The processing of the charger immediately makes a reasonable impression. The casing feels good; Everything is rounded; there are no sharp edges or corners. The black surface looks visually good, there are no scratches or scuffs. All in all a very high quality device.
Affixed on the bottom rubber feet provide a stable and non-slip operation on the table. These are really handy; other equipment without rubber feet slip constantly back and forth.
A switch there is not in this charger. As soon as the power supply unit is in the socket, the LCD lights up in blue. It is operated via a single button, making it very easy and user-friendly.
All 4 charging slots are used individually, batteries can be fooled easily and take out.
The charger does not take a lot of space on the table; measuring approximately 13.5cm x 10cm x 3.5cm it is not particularly large. The power cord is long enough: From the AC adapter to the charger about 100cm.
Use the charger is simple and self-explanatory; without manual I could take the charger into operation quickly. There is one charge and a discharge program. When discharging the battery, the capacity is measured and displayed on the LCD. In both programs you can choose between a current of 0.5A and 1A. At the end of each program, the charger will beep; This beep is pretty loud and unpleasant. Even a locked door is not an obstacle.
A detailed instruction manual with technical data is not available.
The capacitance measurement I checked with several batteries:
The difference between the indication of the battery manufacturer and the capacitance measurement of the charger is less than 10% for all measurements.
In the photos, respectively the nominal capacity of the batteries and the blue LCD can be seen, the measured capacitance.
Conclusion:
For me, this 4-way charger is a great enrichment. I can load multiple batteries simultaneously and have everything under control.
