Oh? Interesting. How long will one of those battery packs last?i honestly just use a large battery pack meant for cell phones, leave it in the glove compartment, $20 solution
i switch from USB power to battery only when i need to (parking on the street in an unknown area), take the battery home to charge when it's low (i actually have two in there)...
i'm sure it depends on how much video activity / how big your battery is, mine lasts around ~48 hours parked in a public garage where the camera turns on every time a car drives past. these power banks are notorious for having fake mah ratings on them so it's not obvious how much i'm actually working with... but they're like $10-30 each hahaOh?
