Some cigarette lighter - to - mini-USB interfere with FM (noticably for Garmin traffic information that comes on a subcarrier.) Any idea whether this 12v wire to mini-USB leaks interference?
The eBay link suggests it could be wired to Batt or Ign. My G1W-C drains my car's battery overnight (when plugged in through the cigarette lighter, which is always on.) I can't vouch for the health of my car battery, and my typical commute is short, but on cold mornings (< +10F) I need a boost if I left the dashcam on, and I don't if I don't. So before I wire this device to Batt, any sense if that's a defect in my dashcam, or if that's typical of what it draws?
