After I pissed away slowly, constantly insert the GoPro to a USB charger, I had decided a charger for the batteries to buy. So I'm on the Baxxtar dual charger (with the original GoPro battery works) come - that another 2 and very high-quality batteries at this price are, then completely convinced me. The Baxxtar batteries had with me the same recording time as the original GoPro battery. The only thing I noticed is that the Baxxtar battery is 0.5mm wider than the originals. When inserting into the GoPro there are no problems, but when you remove you have to be a little careful, so you do not verreißt the red plastic tape. But that is the only drawback, and at this price I am absolutely prepared to accept this.
