When I unpacked the charger was the first that I made only once to look any old batteries that I had lying around and to test the refresh mode. And lo and behold from a battery life of 22 hours usage in my computer mouse on almost 60 hours (or in mAh of nearly 770 to 1980) I find it very impressive. A number of other days, the capacity has doubled. I had the most success with a nearly 10-year-old battery with a nominal capacity of 2300 mAh I have received from almost 430 at constant 1700 (in continuous use so I can make this statement). * * Unfortunately, this device can also destroy some illusions :-( from alleged 3800mAh were at 4 piece Services 1300-1750 ...
What I in on this device very positive think is that you can pick out its charging time literally and not on any automatic is the device itself instructed and I the weakest setting (200mA) selected as this rare the refresh mode to be used must almost always compared to higher charge strengths, on the other hand I've always enough batteries that I've never really need an immediate charge and re-use.
So now we come to the small weaknesses * *
1) The power supply is damn big.
2) The display is contrary to the pics here is not backlit (looks at least in the pictures here in Amazon so than it would a). I find a shame the night if you still want to look quickly if the batteries are fully loaded, one must always first turn on the light. Also, I find a bit too small, the labeling mode, but if the device would be become more voluminous to allow only a slightly larger font would be rather counterproductive.
The next two points are complaints on quite a high level ^^
3) While there is a single channel control but unfortunately none individual bay control and if you take one of the batteries out when it has finished loading and replaced by another, he does not start in the same mode to load as previously selected but returns to normal charging and when pressing the mode button to switch the others remain which have not yet done not receive but also changed (but in the price range normal).
4) It's a pity that this unit still has no way to load Lithium-ion batteries, but as a note at 3 probably not in this price range ^^
