I bought a power inverter at Walmart to plug into the 12v power outlets in my 2016 Honda Odyssey to allow us to charge a laptop. When I plugged it into the power outlets, the "power on" LED for the power inverter wouldn't even come on. I am hearing that the Odyssey 12v outlets won't support plug-in power inverters for this purpose. Any suggestions? Is there an inverter I can buy that will work?
