    "content": "Here in the middle of the US, SAMs Club sells a 500watt inverter that I've had \nvery good luck with, as long as you use appropriately sized feed wire (#10 in \ngeneral for ~10ft run) and supply voltage.  The price is less than $30.00 and it \ncomes with a carrying case.\n\nI have mine outfitted with Anderson Power Pole connectors and harnesses to allow \nme to connect it to a wide range of DC sources.  Normally, it is just plugged \ninto my jack block in the vehicle.\n\nPower source issues:\nMy 1997 honda accord needs to be running with a well charged battery to keep the \nlow voltage alarm from going off (directly wired to battery).  My 2001 Dodge \nDakota will operate, engine off, no problem for quite some time.  So, it really \nis important to manage the incomming voltage source appropriately or else the \ncurrent rate will increase.  The output power, requires the right number of \nwatts of input power.  Depending on the design of the device, a low voltage \nsituation can cause the current rate to reach a level that will damage the device.\n\nGregg Wonderly\n\nReicher, James wrote:\n> I've had good results running my HD73 rotor, using a 300W inverter,\n> purchased from a big-box store discounter, for about $40.\n> \n> I bought it initially to run a 13\" TV with a built-in VCR in the car for\n> my harmonics when on long trips.
