How long and how much power does it take to charge Apple Watch using a Chargebus 1650 multi charger?
It took around 3 hours to fully charge the 42mm Apple Watch from a completely drained state to a fully charged state. With the power current peaking at 0.36 Amps. This is a third of the power that the iPhone uses to charge.
However, Apple watch continued to charge at a low 0.1 Amps even after being fully charged. This is why Apple watch can still feel warm to the touch after an overnight charge.
