The processing of the V-Mount battery is really flawless, very high quality, robust and high quality. In addition, it is also really very compact for the performance it brings. This makes it perfect for on the go. In addition, he also makes a lot in terms of design and appearance. It really feels like a real luxury product. A truly essential piece of equipment, especially for filmmakers. So that you can focus on your work for several hours in continuous operation without having to constantly concentrate on battery consumption and changing the batteries. It charges my Sony DSLR camera with no problem. Even if you don't have the time to fully charge the battery (which takes a little longer here), you can reach approx. 3/4 within a very short time so that you can continue to work without any problems. In addition, not only cameras, but also all other accessories such as cell phones, laptops, tablets, etc. can be charged. The Mini V Mount battery is also designed for charging the devices at the same time, because various connections are integrated, namely USB-A, USB-C, 8 ＆ 12 V DC and D-TAP. The battery performance is also really strong at 6700 mAh. A nice additional feature of this product is the LED display, on which you can always clearly see how full the battery is. Sure, the price is really high, but you get a lot for it. Quality has its price. However, I would only recommend it if you really intend to use all the connections and really want to charge several devices (possibly at the same time).
