 AC-only items will require an inverter.  [[electrical:12v:wallwart|Devices that run off a "wall wart" adapter]] almost never require an inverter.
+===== efficiency =====
+Inverting from DC to your local shore power spec will necessarily incur losses.  These might be 10-30%, depending on the inverter, the inverter's efficiency spec, etc.  In the absence of hard information you might use 20% losses as a rule of thumb.  This means it will require 20% more power to run your load than the rating spec.
+w * 0.8 efficiency = 60w demanded from the system

   - some can bond shore and battery power to support heavy 120vac loads
   - charge battery banks like a [[electrical:converter|converter]]
+  - some also handle solar charging
 They tend to be [[https://amzn.to/2KMcImw|expensive]], some over $1000.
+Note:  the Victron Multiplus line has outputs for maintaining the starter battery:
+>> The main DC terminal can supply the full output current. The second output, intended for charging  starter battery, is limited to 4A and has a slightly lower output voltage.((https://www.victronenergy.com/upload/documents/Manual-MultiPlus-3k-120V-(firmware-xxxx4xx)-EN.pdf))
