Is a mini-compressor better or worse than a bike pump for inflating the flat-jack?
Answer: a mini-compressor is more comfortable, because she takes less energy which is good, the more so in warm holiday/summer weather, but a compressor is more risky than a bike pump. During the pumping process with a mini-compressor, the pumping person can be distracted by a mobile phone for example. During the telephone call the compressor just keeps on pumping, and people can forget the compressor, which then over-inflates the flat-jack in the end. This can result in an exploding flat-jack, if the mini-compressor pumps her up above 1.2 bar.
