Batteries not used yet so I can not attest to the more or less autonomy than the original, purchased for a GoPro Hero 4 Silver (I can come back later on my comment ...). The specific tab on the latest generation batteries GoPro is as beefy as the original ... I'd like someone here the same battery brand (model Hero 2) and he never asked me to worry, they had little or bow the same autonomy as the original. I loaded without the real problem 3 batteries (including the original) with this charger. The slot is more fragile than the GoPro Hero 2 (see use) as these are strips you just do not go there as a nag and do it more gently than the other. The advantage is that you can take only one charger when traveling if one already has the old models: in fact simply unclip the top: the rest is the same! (See photo) At this price the substantial economy is significant (Charger + 2 batteries do the math .. I did not hesitate)
