Will my Canon battery charger work on 220 V power?
The label says it is compatible from 100V to 240V, 50 or 60 Hz. Thus, a 230V (perhaps 220V) 50Hz mains, as found in Sweden, will work fine with this charger. You'll need to adapt the U.S. plug style ...

Is always leaving power on bad for CMOS?
I take it you mean leaving the switch always on, and letting the camera go to sleep after a timeout (as most cameras do).
This isn't going to hurt your camera in any meaningful way. It just wastes a ...

Can I maintain the same flash pulse duration but increase light with multiple flash units?
Yes.
Speedlights reduce the light output by turning the "power" off earlier.
This way the time the flash is on is reduced, which results in shorter flash duration for lower power flashes.
