Carl - I think it will be handy and convertible back in minutes.
The Odyssey comes with a built in phone charger. It is not as fast as the one that comes with our smart phone so I've added a dual charger capable of 4.2 amps @ 5 volts amps for our smart phones or pad.
I also purchased a separate charger that uses that same outlet capable of charging my Chromebook, a 12 volt Laptop, directly from the outlet. Each of these items were under $10 on Amazon.
I also purchased a One Touch Universal mount. It has a sticky gel base that can be rotated every which way. It is designed to hold a smart phone. You only push one button to lock or unlock the phone.
We use it when we use the phone as a GPS system, relatively rare for us. It will be more often used to hold our Tyre Dog Monitor. We use this to monitor the temperature and pressure of our Scamp's tires
while towing. Before the Odyssey we also monitored the rear tires
of our former tow vehicle, a 2004 Honda CRV.
