Nexstar 4/6 SE mount power comsumption

I bought a small USB power meter, and I sandwiched it between my USB power bank, and the USB -> 12V cable which is connected to my Nexstar 4/6 SE mount.

It was drawing 0.51A at 5.14V which is less than what I imagined.  When both motors were slewing at maximum slewing speed, it measures around 0.8-0.9A only!  Therefore, a USB power bank should be enough for a whole night of observation.
