Advantages of this method of powering the camera are: firstly – high reliability, because there are no additional transducers between the power supply and the camera.
And secondly, all the current that is able to give the battery comes directly to the camera. And, consequently, this method of power is suitable for both video and photography.
A common advantage for the above methods of powering the camera is that the model of the battery does not contain fuel elements and does not heat, unlike the native battery.
This is especially true in cameras inclined to overheating when shooting video, such as APS-C cameras Sony. This applies to the owners of cameras Sony A6300, A6500, despite the fact that these cameras can be natively powered from the powerbank.
