I carry a backup device instead. I could use a chart and compass if I had to, but suddenly switching to that while flying solo would be dangerous in my opinion because I wouldn't be able to do it quickly while also maintaining a lookout. Unless I plan to use a chart in advance, but a significant benefit in using a moving map would be lost (time saved in planning, and being able to wander around without so much attention to heading, landmarks, timing, etc).
If my main moving map fails and my backup device also fails, I intend to call a local ATSU or D&D for help immediately.
The other day my main moving map did fail (only a loss of location due to loose power connection to PilotAware). I recalled where I was when I last looked, held heading and altitude, and had my backup (my phone) running within a minute. Then I dealt with getting power back to the PilotAware. I was close to a class D boundary at the time. Had I had any doubt, I would have probably called them before dealing with the backup.
My point is that the ability to fly with a chart and compass isn't really relevant!
