 It is **more efficient to use DC power directly** whenever possible. In particular it is more efficient than running a laptop of phone charger off an inverter.((http://www.cheaprvliving.com/forums/Thread-Here-s-one-for-you-inverter-lovers)) It is **more efficient to use DC power directly** whenever possible.

-AC-only items will require an inverter.  [[electrical:12v:wallwart|Devices that run off a "wall wart" adapter]] almost never require an inverter.  +Note:  **only AC loads will require an inverter**.  [[electrical:12v:wallwart|Devices that run off a "wall wart" adapter]] that output DC almost never require an inverter.  Things that charge off USB (phones, fans, tablets, etc)  can use a [[https://amzn.to/3JmopvO|12v-to-USB port]]. Laptops often have car chargers that run off 12v ([[https://amzn.to/3Wax1Nw|example]]).  Search for "[specific make/model] car charger"

 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. 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.
