Question: are all gopro chargers the same?
Answer: Most GoPros use 5V / 1A, which is standard for most AC adapters. The HERO7, HERO6, and HERO5 models can take up to 5V / 2A. You can use a standard USB wall charger. If you don't have the one that came with your camera handy (or if it didn't come with one), the one you use for your phone or tablet will most likely work.
