I know somewhere I have seen this posted but I can't find it and in case case have a couple of extra questions. I believe I can use a power bank to run my SJ6 Legend if for example I wanted to do time-lapse which runs over the length of battery time. I have an Energizer 20000mAh power bank. Model number: UE20001 Output Power: 74Wh; Input: 5v - 2.OA; Output: 5v - 2.OA. Because I had read that it was okay to use up to 2A I gave it a whirl and it worked okay. However, I would first like to check if it is normal for the camera to get quite warm when used in this way. Also I haven't been able to find anything concrete on whether the battery should be left in or not. I took it out. I found if I took the battery out first it would go into charging mode. If I plugged the charger in while the camera was on with the battery in; then I could then take the battery out and the camera would continue to be powered by the power bank. Can anyone confirm if this is the correct way of using please? Or if I have missed something/done something wrong.
