I had the converter despite the different reviews ordered to go to charge my batteries and a Quadrocopter to be more independent in the future with regard to other batteries or baby bottle warmers. I can not complain. The unit recharges the batteries are reliable and the heat generation is there, but after about 20 minutes still feasible. My Golf7 Variant has a 12V socket in the boot, in the connector of the transducer fits well and tight. Under the box is a small compartment, which I covered with a cloth so it does not rattle during driving. I think so necessarily can not escape less heat than if I put the transformer in a cup holder.
I hope that other devices can be reliably loaded and operated in the future with the converter. The 5,2A battery of copters were before the endurance test.
I can recommend the very converter. Price / quality I find very good.
