Thanks for the details. I had a long road trip over the weekend and the kids used the inverter on DSes, iPod Touch and a Toshiba laptop with no problems. I understand that the technology has a general problem, but most things seem to handle it better than the a2109. Over the years, several different devices have worked fine with that inverter. IPads, notebooks, phones, other Android tablets, TVs and hand held games; every one worked fine.
