Let me rephrase that. I have used a zefal hpx4 a couple of times. They can get to a higher pressure than a hand pump, but it is still a bit of work to get to a good riding pressure. They are probably the best option for a portable pump, but I am under the impression that the OP is asking about pumps for general use, not just on the road. Given the choice, I would certainly use a floor pump over a frame pump.
