Below is a section from the Dash Cam Talk web page for the SJ4000 camera https://dashcamtalk.com/sj4000/#Burned_Charging_Cable. You can see there was a serious problem with overheating. I also had an adapter that severely overheated to the point where it and the camera were too hot to touch. I put on oven mitts in order to unplug and disconnect them. This was one of two cameras I had to return.
This brings up two questions. First, why aren't the AC adapters supplied by SJCam UL (Underwriters' Laboratory) listed (in the US)? Every adapter for every other portable device I own is UL listed yet four out of four of my SJCam adapters were not. Although compliance with UL is voluntary as far as I'm aware, reputable manufacturers of all kinds of electrical and electronic devices manage to seek and receive a formal UL listing. My belief is that if SJCam adapters demonstrably complied with UL standards and received UL approval then the likelihood of overheating would be near zero.
Second, there is currently no way to register the product as far as I know. Products should be registered in case there is a need to issue a recall to comply with a ruling by the US Consumer Product Safety Commission (CPSC). The fact is that I should have notified the CPSC of the overheating adapter but I wasn't sure if it was a one-off or a repeated problem. Now I know. I would also think it would be in SJCam's best interest to keep in touch with customers to build brand loyalty, notify them of firmware upgrades etc.
Is anyone aware of any way to register your camera with SJCam? Has anybody else had a problem with severe overheating of their AC adapter?

Burned Charging Cable
One owner has claimed that he has had 2 charging cables explode / burn up. The camera becomes unresponsive once this happens. Below is a picture of the disassembled charging cable with the damaged circuit board.
