Powerbank Battery Power Resources
There are some times when you just can't get a 13 amp power source close to a piece of equipment, are concerned about trailing cables or a power supply doesn't exist in the area.
The answer could possibly be the use of mains chargeable battery Powerbanks.
An example might be a Smartphone on a tripod being used as a fixed webcam and tranmitting a video stream over wi-fi to the controlling laptop using Iriun or similar software. In that kind of scenario something like this could be utilised :
