[RE-wrenches] Consmption current?

[Exeltech]

"Supply current" is for the USB port.  The USB standard limits the output current supplied by a USB port to 0.5 amps.

"Consumption Current" is for the unit itself.

The 10A figure is of importance here.  The 10 amps is likely a peak value (volume dependent) at 13.8 VDC (nominal).

The audio output is rated 50 watts x 4 channels = 200 watts.  At less than max volume, the unit will use correspondingly lower current .. unless the output amplifiers are running class 'A' (highly unlikely) .. but that's a topic for another day, and another venue.
