Niner, do you have another method to check amp flow?
Of the three watt meters I have used, 2 of them are very inaccurate under 0.8 amps.
Just last night I saw my laptop drawing 0.07 amp via my wattmeter on Standby with a ~85% charged laptop battery. I broke out my clamp on meter and it read 0.68amps.
Moral is, you can't trust these inexpensive wattmeters at such low currents. Corroborate the data with another tool.
