I did file a warranty claim online. I love the bag ... but if it wasn't the switch it was something in the AC cord. It caused the circuit breaker to flip and it completely fried the electrical socket. There is no way that I will plug it in again and risk fire.There was an AC controller switch issue in a limited number of bags produced 4-5 years ago. Some of the switches in this batch may fail as a result. The issue was identified and resolved after that batch, and hasn't been present in bags manufactured since that time. If someone has a bag that fails for this issue beyond the 2 year warranty period we will still address it for you. The fix takes about 10 minutes to complete. Kulkea may be reached for warranty claims and this issue via our our Adventure Warranty program.

I have no problem with the DC cord in the car and that is what I have been using. We moved to Reno recently and have a 40 minute drive to the slopes so the DC cord works sufficiently for this purpose.
