AUSDOM A261 Dash Cam

I wish dash cam makers would use the relatively new (most people haven't heard about these yet) variable and rechargeable super capacitors. The relatively small number of current dash cam's that do have capacitors use traditional capacitors that do not replace batteries, but have just enough capacitance to allow the camera to save the currently recording file to memory, so your video clip isn't lost in the event of a power failure (unplugged, turned off, major accident that disrupts power). The newish super capacitors are called 'super' because they can store power and release it with control, much like a battery; in fact they can in many applications actually replace batteries. There are many advantages to super capacitors over batteries, if anyone is interested in learning more about this; this link is a great place to start: http://www.instructables.com/id/The-Forever-Rechargeable-VARIABLE-Super-Capacitor-/

ConsumerAdvocateSupercapacitors are cool (I've used them as pseudo UPS on SBCs before) but they're more for the technically-inclined and might not be suitable for consumer devices (yet). For starters, they're:
1. Huge (compared to batteries) and require additional circuitry - and you don't want a gigantic device sitting on your dash
2. Shorts lead to extreme heat that can can burn you or melt your dashboard or the device
3. Expensive
TLDR: There's a lot of advantages in using supercapacitors, but they're not really applicable to dashcams. Meanwhile, their cons make them very unwieldy for consumer-based applications.
