Now you can charge your battery when you out in the back country for that epic week of riding.
Will work with all Magicshine, Gemini and Gloworm batteries.
Output is 8.4V, 0.8A so it will take about twice the time as the wall charger but it gets the job done.
The drain on your car battery is negligible so no problem leaving it on overnight or during your day ride.
