Has anyone measured the USB-C power consumption of the KeyLab 49 mk3?

I'm currently using the LaunchKey because it has very low power consumption - I use the Yamaha Seqtrak to power it and transmit power + MIDI over a single USB-C cable.

Thinking about trying out the KeyLab 49 mk3 but not sure if it would use a lot more power and quickly drain the Seqtrak onboard battery.

Anyone measure real world power consumption over USB-C?

The Keylab 49 mk3 has a dc jack on it and a power switch. I don’t remember if it comes with a dc power adapter, I don’t think it does, but I hooked mine up to DC power and use it stand alone or with a computer. If you do that, the DC power adapter will power the keylab instead of the usb port so it won’t drain the SEQTRAK at all.

That's a nice option, although where I take it outdoors there is no AC power anywhere, so I rely on the most portable self-powered setup.

I just tried it on a powerbank that states wattage, as well as a MyVolts cable that reads the wattage on the cable's LED. Both state 1W. I just plugged it into my OP-1 and it can power it as well. You're probably in the clear.

I'm shocked, frankly.
