| Not clear what you are saying here. Twenty amps for a typical 5 hour sunny day gives you 100 AH which is 3-6 times the typical camper's usage.

Comparing notes. Where did you mount yours in 178? I mounted mine in the panel, near door, that is the dinette passenger seat. I can open door and look at 12v status and use USB and 12v charge with device resting on dinette cushion or table. Drilled a hole thru floor of front storage compartment, and ran 14 gauge wire into floor of electrics bay and used spare fuse for connection point. Works great, silicone holes and secured wiring below TT and in front storage area. From what I have seen the 179 is much easier to access. |
I try to use what I call the service panel for all things utility...
Here is a pic...

OP stated 20 amps, not 20 watts...

You're welcome. I'm not familiar with the 172, but if you can mount the device in an area near the power panel where it is convenient to use, and draw power directly from a new run to the 12v side of the power panel, that would be best. You can certainly tap in to other wires as well, but depending on what you tap...it may limit the amount you can draw, but usually plenty power available for charging stuff, no problem. If you choose not to make a new run to the power panel, make sure you install an inline fuse on the power side of the tap and use a fuse rated appropriately.
If one of your geek friends reads this and says "huh" don't let them do it... :-)
