"Functional, Aesthetically Pleasing, and 30 bucks."4.5 starson by cosmostein
Pros: The life of the Energizer Batteries seems to be 20% - 100% better then comparable batteries designed for the Wii, Visibility of LED's which indicate charging status is good due to large size, reasonable price
Cons: No stand alone USB port like PS3 model, No means to charge Energizer Wii-Fit Battery,
Summary: The comparison to the Nyko upright Wii controller charging stands are very easy to make, because they look very similar.
However, that is where the comparison should start and stop.
At first the Energizer and Nyko units in terms of charge time and battery life seemed identical. The difference seems to make it self clear a month or so into ownership of the units.
The Nyko Unit after about two months offered me a battery life of nearly half of what it was after its first charge. The batteries included with the Nyko unit seemed to degrade fairly quickly to a point whereas after three months the life was > 30 minutes after a full charge.
The batteries that are included with the Energizer unit seem to offer a longer life cycle, whereas about two and a half months after purchase the output is about 80% - 90% that of the first charge.
While the Energizer unit is more expensive then the Nyko Unit, the cost savings is ultimately erased the first time you need to purchase replacement batteries for the Nyko Charger, and becomes a more expensive unit the second time you ultimately have to change the batteries.
As for the charging base itself, it truly is apples to apples. They are very similar aside from the odd angle the Energizer units holds the controllers which results in slightly larger footprint.
The Charge times generally seem to be similar, although I seem to recall the Nyko charge cycle becoming shorter and shorter as the life of the battery decreased.
The Energizer unit is far from perfect, however without a proper first party option from Nintendo this seems to be the best option thus far.
