Abgeraucht The first time !!! Rather what pyrotechnician

The title says it all. Tried to charge 820 so that a Lumia. The part left unattended in the cigarette lighter socket to get is extremely dangerous !!!! ... Normally I do not write feedback, but in this case I find myself in the obligation to anyone who has purchased this unit or buy want to warn. Fortunately, I've noticed the smoke before the part was merged with the socket and I could just pull the plug on time. The capacitors are then still burst, so I had to immediately throw out the window of my vehicle the device. The only thing that remains is the delicious Ampere / fish smell.
