I have a Garmin fishfinder which doesn't have built-in auto off. Twice, I had forgotten to turn it off & then 2 weeks later when I get to boat ramp, dead battery.
So I bought this timer relay, was $20 delivered.

You can program it in various ways. I set it up to turn off after 2 hours. It doesn't take hardy any power when off (spec says it would take 5 years to drain a 9V battery).
Happy ending on this project!
