The battery performance is excellent and I notice no difference from the original BLN-1 in practice. Certainly if you were retested in the right laboratory conditions, one would come to x% less allowances. But that is to get over because it costs not even half the price of the original. They are recognized properly in my E-M1.
The charger is very versatile. A normal power cable and a cable for charging in the car are included. This was very important to me, as I often have to travel with the camera and then the battery in the trunk load can at the local port. The shop is also on the car port quickly. Original and replica batteries several manufacturers were all charged properly. In a pinch, you can charger even with the new standard mobile connection Micro USB to charge (I have not tested). A USB output, there are also so that you can also charge his mobile phone or tablet with adequate cable. This function also went with me properly (Loaded I have my Bluetooth Headset and iPhone 6 and iPad mini)
Conclusion: price / performance is amazing here. If one looks replacement batteries for its Olympus can be here quasi blind slam!
