Very powerful: a battery charger with a charge capacity equal to more than double a fuel cell or a 100W solar panel
Fully automatic:
starts when the battery is running low (11.9 V) and stops when it is charged (14.5 V).
Quiet: thanks to thick soundproof insulation, there is a very low amount of emitted noise (only 51 dBA at 7 m) which is almost imperceptible.
Practical and ecological: just connect it to the gas cylinder already in your camper.
