The many 1 * -Rezensenten can I join. The device is quite bulky and heavy (lead acid battery!) And to position themselves accordingly unwieldy in the car. The idea for such a thing to realize such a "heater light", could not be realized. But the air is not hot enough and the battery does not last long enough. Charging while driving is not enough to fully recharge the battery - therefore you have to then set the house, charge there, then device after charging back in the car .. De facto therefore only extra expense that is the result of all proportion. My device warms now only the electronic scrap containers from our waste disposal.
