ideal for cashcams, car cams without the clutter

I would only point out a very welcome Andwendungsmöglichkeit:
Modern dashcams can be set so that they start recording as soon as they are externally supplied with power u. Be switched off when external power source is disconnected. Usually this requires a cable connection to the cigarette lighter. Engine Start = camera; Ignition key out = power off.
Since the Cube 8000M has an on / off switch, you can use them as alternative current donor who is discretely mounted anywhere and connected mtttels a short USB> mini USB cable to the camera.
It turns the battery on / off. That's it.
PS For those who rely on GPS, has possibly unlucky, because often the GPS module is integrated into the charger cable leading to the cigarette lighter.
However, there are cameras where the GPS module is integrated into an otherwise standard USB cable. This is then in the Zigarttenanzünder power supply (or just the battery) inserted.
