Excerpt: I bought this just before my trip to Disney World as I knew that I wouldn't have a whole lot of opportunities to charge my internal battery during the day. This seemed to more than double the life of the battery. To give an example of how long this battery lasts, my wife accidentally turned on the camera and started recording with it while it was packed in our backpack.
Excerpt: Works well to keep our GoPro on line for greater amounts of time. Doing analysis of crash tests the cameras can be set and not worry about minor delays and loss of power. Fit just as if te original with little adaptation.
Excerpt: It is a useful product, but most needing extra battery life would like to also frame their shots with the LCD. Iphones are for suckers. The rest of us just need a simple port that lets us put the lcd pack on this. Seems like a major oversight.
Excerpt: Used the Bacpac on a recent trip to the drag strip just to see if it would meet my needs, it more than surpassed my expectations, Walked around all day taking pictures in the pits and videos of many of the races and still had over half of the battery life to use after a day of off and on camera use that would of killed the standard battery that the go pro comes with, Can't wait to use it in the water on my next trip battery life is well extended you'll love it !!!!
Excerpt: Nice to have the window that shows charge level, also can charge by itself not attached to gopro. The Gopro stock battery setup is the weak link. Always looking for ways to get longer battery life.
