Just messin' around in the barn this afternoon and compared the factory ASUS 12V adapter vs. the factory ASUS 110V adapter run through a 150 watt inverter. This was powering my ASUS Net Book
Running the 12 volt adapter @ 62% of charge / 12.34 volts:
Running a 150 watt inverter and the ASUS 110V wall adapter @ 63% charge /12.33 volts (same programs running):
The Link 10 is not always agreeing with the clamp meter, could just be a speed response time issue, so I need to check my connections and make sure they are clean. Of course I did replace it because it was "buggy" to begin with.. The clamp meter is usually very accurate. Either way I have run both scenarios..
If we use the clamp meter it was 3.12 amps vs. 4.12 amps or a 33% increase in consumption using an inverter and 110V adapter vs. the 12V adapter.
If we use the Link 10 it was 3 amps vs. 3.8 amps or a 27% increase in consumption using an inverter and 110V adapter vs. the 12V adapter.
Not all 12V adapters are created equal. The factory ASUS adapter is designed to always feed the laptop 12 volts whether it sees 10 volts or 18 volts. This computer is quite finicky about it's 12V power input and it needs to be 12 volts not 14.2 or 10.5. The frustrating this is that I own about 5 12 volt adapters including a Targus and an iGo neither of which are compatible voltage wise. Most laptops can run on more flexible voltages but this one can't.:cussing: $349.99 for the computer and $46.99 for the ASUS 12V adapter..
