A lot of people will put a 2KW inverter, or larger,  on a single 12v battery, but this can be compared to a 5 second drag car, which uses 5 gallons of gas to run the 1/4 mile, but then only having a 2 gallon gas tank."  -- sternwake((https://vandwellerforum.com/showthread.php?tid=256&pid=3823#pid3823))

 Note that motorized equipment like the drill likely have **different current requirements for startup and for running**.  Getting that motor spinning takes more power than running it.    There are tricks you can use to minimize the start load, like starting a sewing machine at a low-load position.((http://www.cheaprvliving.com/forums/Thread-Is-it-possible-to-Boondock-with-an-electric-sewing-machine?pid=165956#pid165956)) Note that motorized equipment like the drill likely have **different current requirements for startup and for running**.  Getting that motor spinning takes more power than running it.    There are tricks you can use to minimize the start load, like starting a sewing machine at a low-load position.((http://www.cheaprvliving.com/forums/Thread-Is-it-possible-to-Boondock-with-an-electric-sewing-machine?pid=165956#pid165956))
  
-The best way to understand how much your 110v equipment needs during startup/running is to use a **power monitor** like the [[http://amzn.to/2fdgIrs|Kill A Watt]]. You may find that even non-motorized 110v items run at much lower power than their labeling would suggest.+The best way to understand how much your 110v equipment needs during startup/running is to use a **power monitor** like the [[http://amzn.to/2fdgIrs|Kill A Watt]].
