As a practical matter, I think the Garmin 396 will require ship's power as
well. It has rechargables that recharge from your 12 v. outlet.

The AvMap EKP-IV has backup battery capability to run the unit for about an
hour after loss of power. You supply your own AA rechargeables. In normal
use it's powered via the auxillary power receptacle a.k.a. cigar lighter.

One thing I have noted about my EKP-IV is that it produces radio noise on
the aviation frequencies.
