I chose the Genius10, mostly because it has twice the watts and charges twice as fast but it doesn't cost twice as much as the Genius5.
The Genius10 has 12v Supply and 6v AGM options, 2 features the Genius5 lacks. The Genius5 is likely sufficient for a Ridgeline and most vehicles but with the Genius10 I'm confident I won't need to upgrade my charger if I change to different vehicle in the future.
Which ever one you choose I highly recommend getting the matching NOCO case. They are very nice, have pockets, straps, a handle and are worth every penny.
