Actually we had the 12V plug also melt. I had forgot about that, The plug that connects the ARKPAK to your vehicle melted. I replaced the plug , thinking it was a fluke and maybe a mismanufactured plug. Then several weeks later during our trip, after being on the road for 8 hours , I smell smoke, then my wife says the back of the FJ is smokey. I pull over immediately and find smoke rolling from the lid compartment under the circuit board. I disconnected everything. This was really strike two. The owner of ARKPAK, said he would send me a new circuit board, and I immediately declined, thinking there is no way I want this garbage in my vehicle. And then after telling him that I did not want to have a fire hazard in my vehicle , he said they had good insurance. That was amazing to hear him state that. So , I do not miss a beat to warn others of this product.
