As you know, the camera is not specifically designed as a DashCam with interference suppression circuitry, voltage stabilizers, large smoothing capacitors and all the other electronics necessary for a traditional DashCam. It's just not possible to build all this extra circuitry into such a small case. The Mobius also doesn't have a G-sensor or GPS receiver or monitor, so I think it should be obvious that the camera isn't a typical DashCam but rather a camera designed for many usages.My Mobius has a battery in it, and it should be perfectly capable of providing the necessary voltage to the board with it. As to the charging circuit, if this isn't a cheap design as you seem to imply, it should be designed well enough to withstand voltage spikes and/or drops that a car can have, otherwise the device shouldn't be marketed as a dash cam, should it? And what comes to the I/O pin sniffing for the voltage, low voltages are no issue and high voltage spikes, if any, can be handled to an extent, if the board is properly designed.
The Mobius was designed to accept a stabilized and clean power supply of 5V following USB standards. It was NOT designed to accept a 'dirty' power supply. The manual states very clearly that you need to use a quality charger.
If there is a battery in your Mobius then you must ensure a clean and stable 5V supply. If this is not the case the charger IC chip will constantly switch it's charging circuitry between on and off. These fast on/off charging cycles will not only heat the charging IC but will also heat and destroy the internal battery and possibly destroy the Mobius at the same time. In the past, bad 5V chargers have been the cause of destroyed and melted cameras.
