Original LUMONITE SnapChargerUSB charger (v.4) for LUMONITE Compass Mini R and Compass R lamps. If you want, you can buy several chargers and charge your SnapCharger-compatible headlamp in several places, such as in the car, at home or at work! Compatible products: Lumonite Compass R Lumonite Compass Mini R Note! The charging cable in question may not work correctly in the older Compass R and Mini R lamps, where the original charging cable was slightly larger. In these lamps, the magnet inside the charging cap may be facing the wrong way, because in older models the charging cable and charging cap were so-called mated.
