Q: Please tell me how this works out: Stated Power: 500W Battery: 16.8V 2000mAh == ONLY 33.6 Watts Where does the rest of the 500W come from?

JoeHo A misunderstanding: the battery CAPACITY is 2000mAh or 2Ah. At 500w, the grinder would draw almost 30A (or 15C - mind you, not many batteries can do that!)That means the battery will LAST 4 minutes before its flat at full load. I doubt that you will be able to use that much power with a 90mm cutting disk.... so I estimate that the battery will last on average 10 to 15 minutes of actual use.Hope that helps.

Q: what does au plug mean? does the power port on the power supply differ or only the included power cable?

4000W piek zuivere sinusomvormer DC12V / 24V / 48V / 60V naar 220V Power Inverter Voltage Converter
US$193.99 US$232.99

Q: Has anybody had a look at the output of any of these Pure Sinewave inverters on an Oscilloscope. Most of the English reviews I read say people tested it by plugging in a Hair dryer or Sanwich maker or Electric Drill and it worked OK. Unfortunately that tells us nothing about the type of waveform being produced.and proper test results seem very hard to come by. I am surprised the manufacturers don't

JoeHo None of the specifications are either true or meaningful. They are only for marketing purposes. The IGBTs in the last one I bought here were suitable for a maximum of 960W, but the inverter was advertised as 2500W maximum 5000W. simply all bullsh1t
