I am looking at purchasing an inverter to use for charging computer, video camera, GPS battery chargers and the like. I might also look at running small colour TV as well. Has anybody got any recommendations re the size I need and comments related to pure sine wave versus "modified sine wave" supplies.

There is some info at http://www.motorcare.com.au/inverter.htm which gives some numbers for typical power usage and some links to inverter units. For info on pure vs. modified sine waves check out http://www.baintech.com.au/whatis.htm

Hope this helps

Mark,

All appliances have the power rating on them in Watts or Amps, it is law. So you can easily determine the size required, just allow a margin between the maximum load and the CONTINUOUS power rating of the inverter. I would allow 50%, but 75% should be fine. Charging batteries will pose little technical dilemma, but check your TV works on modified sine wave before you cash out. You may need to go to pure. Some small TVs run on 12V anyway, so check it out.

Steve.
