I bought this from Conrad for 8,99€ - the still current price - last week. It is certainly not of great build quality, but in my tests it did the job so far
What I have tested:
- NiMH 1.2V rechargable AA cells
- the Fairbuds XL LiIon battery pack
The AA cells were charged to 100%, the Fairbuds XL battery to about 80%.
The charger uses a Micro-USB connector for power. One thing I noticed was the the charger certainly got pretty warm when charging the AA cells, but not as much with the LiIon pack. So I guess it serves as a working backup, but the build quality does not suggest regular use to me.
