Our kayak was supplied with a separate (manual) pump and manometer, but I've ended up using the one from our caravan awning instead as that has a manometer built in - it's not as accurate but it's good enough.
I'll throw in another vote for a manual pump for the kayak. It's not a lot of effort, quicker, quieter and as eightpot says you can take it with you.
Top hint, especially on hot days - if you can, put the boat in the water for a few minutes and the recheck the pressure before you set off. The change in temperature can drop it quite a bit and make the boat overly flexible. The flip side to this is you need to watch out for excessive pressure if you haul out and leave the boat in the sun.
Have fun - our kayak has been one of our best purchases of recent years.
