Yes, I use it to charge Hero 8 batteries.

Yes, the hero5, 6 and 7 use the same batteries so the product is compatible with hero 7 black.

It works for me without any problems, try again or contact the customer service.

Hello. No. Here is the matching product GoPro Dual Charger with 1 x Spare Battery (Power Supply, Hero 9)

I even paid CHF 57 for the charger 3 weeks ago. This jump in price can hardly be explained by the purchase price. I think it is due to the new 'spot pricing' concept or whatever digitec/Galaxus calls these fluctuating daily prices. In any case, it's more than annoying. Until now I had confidence in the digitec/Galaxus pricing policy. Whenever an item was available, I ordered it there. With the current pricing policy, however, I will certainly not continue to do so and look more left and right. And then procure accordingly. Digitec/Galaxus should think twice about this policy, because keeping existing customers is much more efficient than trying to win a few new ones with obscure price promotions. I am curious about the answer from Digitec/Galaxus.

Yes, it is also in the title, but from the Hero 5 onwards, all Gopros have the same battery.

Hello Miroir Yes you can in this case. Most smartphone adapters have an output voltage of 5V. This voltage is also required for the GoPro charger.
