Does the trick. Plus the pump intake has the same diameter as other storage bags sold here too. So you can use it on those (wait a while tho). The other way round (using hand pump on these bags wouldn't, but who would want that) One missing star=usb connector is not well aligned with plastic enclosure, and too deep. So only some of my cables can reach it, and even those do it quite unstably. I will have to drill a bit
