We use this one and it works really well. We use it for packing to go on holiday as well (so that the bags will end up the same size both ways if you see what I mean).
we have the quick pump which seems to be a rechargeable version of the one above and it will not take a vac bag down anything like the hoover at home will
the one big thing that we found is the valve on the bag is about two inch diameter and the hose on the pump is one inch diameter, so if you could make an addapter thne it may take the vac bags down better
The Coleman does a great job - we've even sucked our (very large) tent canvass into a bag. We use Aldi bags and the sucking inlet on the pump clips directly and very tightly onto the valve on the bag.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
