A 700 watt power supply at full tilt is only pulling 10 amps on the mains cable. Plus at big events your going to have waves of people charging, not everyone all at the same time.

Roelof your lucky in Europe with 220, your going to be pulling about half the amaprage us poor Americans have to pull. So our 700 watt ups would be about 5 amps at the mains.
"Only" 10A on the mains cable? Typically North American mains are usually only rated for 12A-15A or around 1400W-1800W. I factored in the AC vs DC current ratings when I made my initial post.

Also, your math seems off. 700W on 220V is about 3A, and on 120V is close to 6A.
